JSON (JavaScript Object Notation) is light-weighted designed such that humans can easily read data interchange and it’s execution.

The JSON format was originally specified and developed by Douglas Crockford and is described in RFC 4627 license. The JSON filename extension is .json.

JSON is based on the object notation of the JAVASCRIPT language and its standard only. It does not require JavaScript to read or write because it is made in text format which is language independent and can be run everywhere. JSON notation contains these basic elements which have JSON advantages in JAVASCRIPT:

1. Objects: Objects begin and end with curly braces ({}).

2. Object Members:  Members consist of strings and values commas(,) separated

3. Arrays:  Arrays begin and end with braces and contain different values.

4. Values: A value can be a string, can be an object, an array, or the literals

5. Strings: Strings are surrounded by double quotes and contain the Unicode colon (:). Members are separated by commas(,).Values are separated by commas(,). true, false or null.character or common backslash escapes.

JSON Example

{
  "first_name": "Rajeev",
  "last_name": "Sharma",
  "email_address": "rajeev@ezeelive.com",
  "is_alive": true,
  "age": 30,
  "height_cm": 185.2,
  "billing_address": {
    "address": "502, Main Market, Evershine City, Evershine, Vasai East",
    "city": "Vasai Raod, Palghar",
    "state": "Maharashtra",
    "postal_code": "401208"
  },
  "shipping_address": {
    "address": "Ezeelive Technologies, A-4, Stattion Road, Oripada, Dahisar East",
    "city": "Mumbai",
    "state": "Maharashtra",
    "postal_code": "400058"
  },
  "phone_numbers": [
   {
   "type": "home",
   "number": "9975666694"
   },
   {
   "type": "office",
   "number": "9822117730"
   }
 ],
 "date_of_birth": null
}

JSON Advantages

Here are top advantages of JSON every developer should know:

1. JSON is Faster:

JSON syntax is very easy to use. We have to use only -> as a syntax which provides us an easy parsing of the data and faster execution of the data. Since its syntax is very small and light weighted that’s the reason that it executes the response in the faster way.

2. Schema Support:

It has the wide range of supported browser compatibility with the operating systems so the applications made with the coding of JSON doesn’t require much effort to make it all browser compatible. During development, the developer thinks for the different browsers but JSON provides that functionality.

3. Server Parsing:

On the server side parsing is the important part that developers want if the parsing will be fast on the server side then the only user can get the fast response of their response so in this case JSON server-side parsing is the strong point that indicates us to use the JSON on the server side.

4. Tool for sharing data:

JSON is the best tool for the sharing data of any size even audio, video etc. This is because JSON stores the data in the arrays so data transfer makes easier. For this reason, JSON is a superior file format for web APIs and for web development.

JSON Disadvantages

First and foremost, in JSON has no error handling for JSON calls. If the dynamic script insertion works, you get called and will get the response perfectly.

If not inserted, nothing happens. It just fails silently. For example, you are not able to catch a 404 error from the server, Nor can you cancel or restart the request. You can, however, timeout after waiting a reasonable amount of time.

Another major drawback of JSON is that it can be quite dangerous if used with untrusted services or untrusted browsers, because a JSON service returns a JSON response wrapped in a function call, which will be executed by the browser if it will be used with untrusted browser it can be hacked, this makes the hosting Web Application Vulnerable to a variety of attacks.

If you are going to use JSON services, it’s very important to be aware of the threats which JSON have in that and also be aware of the things which can protect it. JSON development has limited supported tools for use.

JSON vs BSON

JSON is a widely used text-based data format that is human-readable and easy to work with in many programming languages.

BSON, on the other hand, is a binary format that is more efficient in terms of size and parsing speed, making it suitable for specific use cases where performance and compactness are priorities, such as in certain database systems.

Designed to address the limitations of JSON, BSON is widely associated with MongoDB, where it serves as the primary data storage format. It provides additional features such as type information, making it more versatile for various use cases.

The choice between JSON and BSON depends on the specific requirements of your application.

Advantages of BSON

1. Compact Representation: By using a binary format, BSON reduces the overhead associated with text-based formats like JSON, saving storage space and bandwidth.
2. Faster Processing: Its compact and structured nature allows for quicker parsing and serialization compared to JSON.
3. Rich Data Types: The support for additional types like dates, binary data, and ObjectId simplifies handling complex data structures.
4. Schema Flexibility: While self-describing, BSON remains schema-agnostic, allowing developers to work with dynamic and evolving data models.

Use Cases of BSON

• MongoDB: BSON is the core data representation format used by MongoDB for storing and transferring documents. It leverages BSON’s efficient traversal and rich data type support.
• Data Transmission: BSON is suitable for scenarios requiring efficient data exchange between systems, particularly when complex data types are involved.
• Embedded Systems: BSON’s compactness makes it a good choice for resource-constrained environments.

Limitations of BSON

1. Overhead for Small Documents: For very small documents, BSON may introduce slightly more overhead than JSON due to metadata like type information and size.
2. Readability: As a binary format, BSON is not human-readable, unlike JSON. Debugging and manual inspection require specialized tools.
3. Size Expansion: While BSON is compact for large, complex documents, it may expand the size of simple structures compared to JSON.

JSON (JavaScript Object Notation) and BSON (Binary JSON) are both data interchange formats used to represent structured data in a human-readable and machine-readable way, but they have key differences:

{
  "name": "John Doe",
  "age": 30,
  "isStudent": false,
  "courses": ["Math", "History", "Science"]
}

\x16\x00\x00\x00
\x02hello\x00\x06\x00\x00\x00world\x00
\x00

JSON vs XML

JSON and XML (Extensible Markup Language) are both data interchange formats used to represent structured data, but they have different characteristics and are used in various contexts. Here’s a comparison of JSON and XML:

JSON and XML are both useful data interchange formats, but JSON is generally preferred for modern web development and API integration due to its simplicity, readability, and efficient parsing. XML is still relevant, particularly in scenarios where complex data structures, document hierarchies, or specific standards and namespaces are required. Your choice between JSON and XML should depend on your project’s specific requirements and the ecosystem you are working in.

JSON vs YAML

JSON and YAML (YAML Ain’t Markup Language) are both data serialization formats used for representing structured data. They serve similar purposes but have some differences that make each suitable for different use cases. Here’s a comparison of JSON and YAML:

JSON and YAML both have their strengths, with JSON being a good choice for machine-to-machine communication and data interchange, while YAML excels in human-readable configuration files and documents. The choice between them should depend on your specific use case and the balance between machine-friendliness and human-friendliness that your project requires.

JSON vs JSONB

JSON and JSONB (JSON Binary) are both data storage formats used in relational databases, but they have distinct differences in how they store and manage JSON data. Here’s a comparison of JSON vs. JSONB:

The choice between JSON and JSONB in a relational database depends on your specific requirements. JSONB is generally favored for scenarios where query performance, efficient indexing, and storage space are important, while JSON is more suitable when human readability of the data is a priority and performance is less critical.

How to secure data and prevent JSON Vulnerability & Hijacking

JSON is not fully secure as we think in the web world, Cross Site Request Forgery (CSRF) in JSON Array hack allow grab sensitive user data from an unsuspecting user.

This is major in exposing a JSON service which contains JSON array, sensitive data, responds to GET requests, Request with JavaScript enabled, request supports the __defineSetter__ method etc.

In Above we had discussed the issue, Now will discuss how to prevent CRSF Attack and Secure sensitive data in following points:

1. Most important, All the request method has to be POST and Prevent your code to accept only POST Request.

$.ajax ({
    url: 'http://yourdomainname.com/login',
    dataType: 'json',
    data: JSON.stringify(dataObject),
    contentType: 'application/json; charset=utf-8',
    type: 'POST',
    success: function (jsonData) {
        // Success callback
    },
    error: function() {
        //any error to be handled
    }
 });

1. Add unique CSRF token in request prevent the application from cookie hijacking and bad requests.
2. Always use secure transfer protocol (HTTPS) in requests.
3. Check special header such as the X-Requested-With: XMLHttpRequest or Content-Type: application/json before serving the response to the request.
4. Code testing tools like checkmarx, SonarQube, Burp Suite etc. will help to application security.
5. User Access log should be managed to check which user activities.
6. Use API and End URL authentication to validate current endpoint.
7. Should use token-based API access such as JSON Web Tokens (JWT).
8. Implement Error handling and Do not provide any technical detail in API call.
9. JSON Validation: PHP 8.3 introduce built-in json validation function. It allows to check if a string is syntactically valid JSON, while being more efficient than json_decode():

PHP < 8.2

function json_validate(string $string): bool {
    json_decode($string);

    return json_last_error() === JSON_ERROR_NONE;
}

var_dump(json_validate('{ "data": { "name": "nitin" } }')); // true

PHP 8.3

var_dump(json_validate('{ "data": { "name": "nitin" } }')); // true

Example of JSON Web Service PHP with MySQL

MySQL Database :

create database IF NOT EXISTS `ezeelive_json_rest_tutes`

--
-- Table structure for table `customer`
--

CREATE TABLE IF NOT EXISTS `customer` (
`customer_id` int(11) NOT NULL AUTO_INCREMENT,
`first_name` varchar(50) NOT NULL,
`last_name` varchar(50) NOT NULL,
`email_address` varchar(100) NOT NULL,
`password` varchar(100) NOT NULL,
`is_active` text NOT NULL,
PRIMARY KEY (`customer_id`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=1 ;

INSERT INTO `customer` (`customer_id`, `first_name`, `last_name`, `email_address`, `password`, `is_active`) VALUES
(1, 'Rajeev', 'Sharma', 'rajeev@ezeelive.com', 'e10adc3949ba59abbe56e057f20f883e', 1),
(2, 'Nitin', 'Bhardwaj', 'nitin@ezeelive.com', '6d071901727aec1ba6d8e2497ef5b709', 0);

config.php

<?php
$conn = mysql_connect("localhost", "root", "");
mysql_select_db('ezeelive_json_rest_tutes', $conn);

json_rest_customer_list.php

<?php
include_once('config.php');
$result = mysql_query("SELECT customer_id, first_name, last_name, email_address, is_active FROM `customer` ORDER BY customer_id ASC;");
if(isset($result))
{
$data =array();
while($d = mysql_fetch_array($result)){
extract($d);
$data[] = array("customer_id" => $customer_id, "first_name" => $first_name, "last_name" => $last_name, "email_address" => $email_address, "is_active" => $is_active);
}
$json = array("status" => 1, "info" => $data);
}else{
$json = array("status" => 0, "msg" => "An error occurred.");
}
@mysql_close($conn);

// Output json header
header('Content-type: application/json');
echo json_encode($json);

JSON Output:

{
  status: 1
  info: [2]
    0:{
     customer_id: "1",
     first_name: "Rajeev",
     last_name: "Sharma",
     email_address: "rajeev@ezeelive.com",
     is_active: "1"
     },
    1:{
     customer_id: "2",
     first_name: "Nitin",
     last_name: "Bhardwaj",
     email_address: "nitin@ezeelive.com",
     is_active: "0"
     }
}

JSON in Python

In Python, the json module allows you to work with JSON (JavaScript Object Notation) data, which is commonly used for data exchange. You can use it to parse JSON data, convert Python objects to JSON, and vice versa.

Here’s a quick guide on how to use the json module:

import json

Convert Python object to JSON (serialization):

To convert a Python object (like a dictionary) into a JSON string, use json.dumps():

data = {"name": "John", "age": 30, "city": "New York"}
json_string = json.dumps(data)
print(json_string)

Convert JSON string to Python object (deserialization):

To convert a JSON string back into a Python object (like a dictionary), use json.loads():

json_string = '{"name": "John", "age": 30, "city": "New York"}'
data = json.loads(json_string)
print(data)

Read and write JSON to/from files:

Writing JSON to a file:

data = {"name": "John", "age": 30, "city": "New York"}
with open("data.json", "w") as json_file:
    json.dump(data, json_file)

Reading JSON from a file:

with open("data.json", "r") as json_file:
    data = json.load(json_file)
print(data)

JSON in Golang

In Go (Golang), the encoding/json package is used to work with JSON data. You can use it to marshal (convert Go objects to JSON) and unmarshal (convert JSON to Go objects) data.

Here’s how you can use it:

Import the encoding/json package:

import "encoding/json"

Convert Go object to JSON (marshalling):

To convert a Go struct or map to JSON, use the json.Marshal() function.

package main

import (
   "encoding/json"
   "fmt"
)

type Person struct {
   Name string `json:"name"`
   Age  int    `json:"age"`
   City string `json:"city"`
}

func main() {
   // Create a Go struct
   person := Person{Name: "John", Age: 30, City: "New York"}

   // Marshal the struct into JSON
   jsonData, err := json.Marshal(person)
   if err != nil {
     fmt.Println(err)
     return
   }

   // Print the JSON string
   fmt.Println(string(jsonData))
}

Convert JSON to Go object (unmarshalling):

To convert JSON into a Go struct, use json.Unmarshal().

package main

import (
   "encoding/json"
   "fmt"
)

type Person struct {
   Name string `json:"name"`
   Age  int    `json:"age"`
   City string `json:"city"`
}

func main() {
   // JSON data
   jsonString := `{"name": "John", "age": 30, "city": "New York"}`

   // Unmarshal the JSON into a Go struct
   var person Person
   err := json.Unmarshal([]byte(jsonString), &person)
   if err != nil {
      fmt.Println(err)
      return
   }

   // Print the struct
   fmt.Println(person)
}

Read and write JSON from/to files:

Writing JSON to a file:

package main

import (
   "encoding/json"
   "fmt"
   "os"
)

type Person struct {
   Name string `json:"name"`
   Age  int    `json:"age"`
   City string `json:"city"`
}

func main() {
   // Create a Go struct
   person := Person{Name: "John", Age: 30, City: "New York"}

   // Open file for writing
   file, err := os.Create("data.json")
   if err != nil {
      fmt.Println(err)
      return
   }
   defer file.Close()

   // Write JSON data to the file
   encoder := json.NewEncoder(file)
   err = encoder.Encode(person)
   if err != nil {
      fmt.Println(err)
   }
}

Reading JSON from a file:

package main

import (
   "encoding/json"
   "fmt"
   "os"
)

type Person struct {
   Name string `json:"name"`
   Age  int    `json:"age"`
   City string `json:"city"`
}

func main() {
   // Open JSON file for reading
   file, err := os.Open("data.json")
   if err != nil {
      fmt.Println(err)
      return
   }
   defer file.Close()

   // Read the JSON data into a struct
   var person Person
   decoder := json.NewDecoder(file)
   err = decoder.Decode(&person)
   if err != nil {
      fmt.Println(err)
      return
   }

   // Print the struct
   fmt.Println(person)
}

Summary of Key Functions:

• json.Marshal() – Converts Go objects to JSON.
• json.Unmarshal() – Converts JSON to Go objects.
• json.NewEncoder() – Creates a new encoder for writing JSON to an io.Writer (e.g., file).
• json.NewDecoder() – Creates a new decoder for reading JSON from an io.Reader (e.g., file).

JSON in NodeJS

In Node.js, working with JSON is straightforward since it is natively supported. You can use the built-in JSON object to parse JSON data and convert JavaScript objects to JSON format.

Here’s how you can use JSON in Node.js:

Convert JavaScript object to JSON (Serialization):

To convert a JavaScript object to a JSON string, use JSON.stringify().

const person = {
  name: "John",
  age: 30,
  city: "New York"
};

// Convert JavaScript object to JSON string
const jsonString = JSON.stringify(person);

console.log(jsonString);

Convert JSON string to JavaScript object (Deserialization):

To parse a JSON string back into a JavaScript object, use JSON.parse().

const jsonString = '{"name": "John", "age": 30, "city": "New York"}';

// Parse JSON string into JavaScript object
const person = JSON.parse(jsonString);

console.log(person);

Read and write JSON to/from files:

In Node.js, you can read and write JSON files using the fs module.

Writing JSON to a file:

You can write a JSON string to a file using fs.writeFile() or fs.writeFileSync().

const fs = require('fs');

const person = {
  name: "John",
  age: 30,
  city: "New York"
};

// Write JSON string to a file
fs.writeFile('data.json', JSON.stringify(person, null, 2), (err) => {
  if (err) {
    console.error('Error writing to file', err);
  } else {
    console.log('Data saved to data.json');
  }
});

Reading JSON from a file:

You can read a JSON file using fs.readFile() or fs.readFileSync().

const fs = require('fs');

// Read JSON data from a file
fs.readFile('data.json', 'utf8', (err, data) => {
  if (err) {
    console.error('Error reading the file', err);
  } else {
    const person = JSON.parse(data);
    console.log(person);
  }
});

Alternatively, you can use the synchronous version:

const fs = require('fs');

// Synchronously read JSON from a file
const data = fs.readFileSync('data.json', 'utf8');
const person = JSON.parse(data);

console.log(person);

Key Methods:

• JSON.stringify() – Converts a JavaScript object to a JSON string.
• JSON.parse() – Converts a JSON string to a JavaScript object.
• fs.writeFile() – Asynchronously writes data to a file.
• fs.writeFileSync() – Synchronously writes data to a file.
• fs.readFile() – Asynchronously reads data from a file.
• fs.readFileSync() – Synchronously reads data from a file.

JSON in JAVA

In Java, JSON can be processed using libraries like Jackson, Gson, or org.json. Here’s a comprehensive guide to working with JSON in Java using these libraries:

1. Using Jackson (Preferred for Most Projects)

Jackson is a widely used library for JSON serialization and deserialization in Java.

Add Dependency:

Maven:

<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-databind</artifactId>
    <version>2.15.2</version>
</dependency>

Usage:

import com.fasterxml.jackson.databind.ObjectMapper;

class Person {
    private String name;
    private int age;
    private String city;

    // Default constructor (needed for Jackson)
    public Person() {}

    public Person(String name, int age, String city) {
        this.name = name;
        this.age = age;
        this.city = city;
    }

    // Getters and setters
    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }

    public String getCity() {
        return city;
    }

    public void setCity(String city) {
        this.city = city;
    }
}

public class JacksonExample {
    public static void main(String[] args) throws Exception {
        ObjectMapper objectMapper = new ObjectMapper();

        // Serialize Java object to JSON
        Person person = new Person("John", 30, "New York");
        String jsonString = objectMapper.writeValueAsString(person);
        System.out.println("Serialized JSON: " + jsonString);

        // Deserialize JSON to Java object
        String jsonInput = "{\"name\":\"Jane\",\"age\":25,\"city\":\"Los Angeles\"}";
        Person deserializedPerson = objectMapper.readValue(jsonInput, Person.class);
        System.out.println("Deserialized Name: " + deserializedPerson.getName());
    }
}

2. Using Gson

Gson is another popular library for JSON handling.

Add Dependency:

Maven:

<dependency>
    <groupId>com.google.code.gson</groupId>
    <artifactId>gson</artifactId>
    <version>2.10.1</version>
</dependency>

Usage:

import com.google.gson.Gson;

class Person {
    private String name;
    private int age;
    private String city;

    // Default constructor
    public Person() {}

    public Person(String name, int age, String city) {
        this.name = name;
        this.age = age;
        this.city = city;
    }

    // Getters and setters
    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }

    public String getCity() {
        return city;
    }

    public void setCity(String city) {
        this.city = city;
    }
}

public class GsonExample {
    public static void main(String[] args) {
        Gson gson = new Gson();

        // Serialize Java object to JSON
        Person person = new Person("John", 30, "New York");
        String jsonString = gson.toJson(person);
        System.out.println("Serialized JSON: " + jsonString);

        // Deserialize JSON to Java object
        String jsonInput = "{\"name\":\"Jane\",\"age\":25,\"city\":\"Los Angeles\"}";
        Person deserializedPerson = gson.fromJson(jsonInput, Person.class);
        System.out.println("Deserialized Name: " + deserializedPerson.getName());
    }
}

3. Using org.json

The org.json library provides a simple way to work with JSON objects and arrays.

Add Dependency:

Maven:

<dependency>
    <groupId>org.json</groupId>
    <artifactId>json</artifactId>
    <version>20210307</version>
</dependency>

Usage:

import org.json.JSONObject;

public class OrgJsonExample {
    public static void main(String[] args) {
        // Create JSON object
        JSONObject jsonObject = new JSONObject();
        jsonObject.put("name", "John");
        jsonObject.put("age", 30);
        jsonObject.put("city", "New York");

        System.out.println("Serialized JSON: " + jsonObject.toString());

        // Parse JSON string
        String jsonInput = "{\"name\":\"Jane\",\"age\":25,\"city\":\"Los Angeles\"}";
        JSONObject parsedJson = new JSONObject(jsonInput);
        System.out.println("Deserialized Name: " + parsedJson.getString("name"));
    }
}

4. Comparing Libraries

5. Reading and Writing JSON Files

You can use any library to read/write JSON files in combination with java.io or java.nio:

Example with Jackson:

import com.fasterxml.jackson.databind.ObjectMapper;
import java.io.File;

public class FileExample {
    public static void main(String[] args) throws Exception {
        ObjectMapper objectMapper = new ObjectMapper();

        // Write JSON to file
        Person person = new Person("John", 30, "New York");
        objectMapper.writeValue(new File("person.json"), person);

        // Read JSON from file
        Person readPerson = objectMapper.readValue(new File("person.json"), Person.class);
        System.out.println("Read Name: " + readPerson.getName());
    }
}

JSON in ASP.NET

In ASP.NET (including ASP.NET Core), JSON is commonly used for data exchange in web APIs and applications. ASP.NET Core natively supports JSON serialization and deserialization through the System.Text.Json library (recommended) or Newtonsoft.Json (optional).

1. JSON in ASP.NET Core

Setting Up a Web API Project

1. Create a new ASP.NET Core Web API project.

   
   dotnet new webapi -n JsonExample
   cd JsonExample
   

2. Add dependencies if needed. By default, ASP.NET Core uses System.Text.Json for JSON handling, but you can add Newtonsoft.Json if required:

   
   dotnet add package Microsoft.AspNetCore.Mvc.NewtonsoftJson
   

2. JSON Serialization and Deserialization

System.Text.Json (Default)

Serialization (Object to JSON):

using System.Text.Json;

var person = new
{
    Name = "John",
    Age = 30,
    City = "New York"
};

// Serialize to JSON string
string jsonString = JsonSerializer.Serialize(person);
Console.WriteLine(jsonString);

Deserialization (JSON to Object):

using System.Text.Json;

string jsonString = "{\"Name\":\"John\",\"Age\":30,\"City\":\"New York\"}";

// Deserialize JSON string to object
var person = JsonSerializer.Deserialize<Person>(jsonString);

Console.WriteLine($"Name: {person.Name}, Age: {person.Age}, City: {person.City}");

public class Person
{
    public string Name { get; set; }
    public int Age { get; set; }
    public string City { get; set; }
}

Newtonsoft.Json (Optional)

Serialization (Object to JSON):

using Newtonsoft.Json;

var person = new
{
    Name = "John",
    Age = 30,
    City = "New York"
};

// Serialize to JSON string
string jsonString = JsonConvert.SerializeObject(person);
Console.WriteLine(jsonString);

Deserialization (JSON to Object):

using Newtonsoft.Json;

string jsonString = "{\"Name\":\"John\",\"Age\":30,\"City\":\"New York\"}";

// Deserialize JSON string to object
var person = JsonConvert.DeserializeObject<Person>(jsonString);

Console.WriteLine($"Name: {person.Name}, Age: {person.Age}, City: {person.City}");

public class Person
{
    public string Name { get; set; }
    public int Age { get; set; }
    public string City { get; set; }
}

3. JSON in ASP.NET Core Web API

Model Definition

public class Person
{
    public string Name { get; set; }
    public int Age { get; set; }
    public string City { get; set; }
}

Controller Example

using Microsoft.AspNetCore.Mvc;

[ApiController]
[Route("api/[controller]")]
public class PersonController : ControllerBase
{
    // GET endpoint to return JSON
    [HttpGet]
    public IActionResult GetPerson()
    {
        var person = new Person
        {
            Name = "John",
            Age = 30,
            City = "New York"
        };
        return Ok(person);
    }

    // POST endpoint to accept JSON
    [HttpPost]
    public IActionResult SavePerson([FromBody] Person person)
    {
        return Ok($"Received person: {person.Name}, Age: {person.Age}, City: {person.City}");
    }
}

4. Testing the Web API

• Run the application:

  dotnet run

• Use tools like Postman or curl to test.

GET Request:

curl -X GET http://localhost:5000/api/person

Response:

{
  "name": "John",
  "age": 30,
  "city": "New York"
}

POST Request:

curl -X POST http://localhost:5000/api/person -H "Content-Type: application/json" -d '{"name":"Jane","age":25,"city":"Los Angeles"}'

Response:

Received person: Jane, Age: 25, City: Los Angeles

5. Customizing JSON Serialization

System.Text.Json Customization

You can customize JSON handling using JsonSerializerOptions.

var options = new JsonSerializerOptions
{
    WriteIndented = true, // Pretty-print JSON
    PropertyNamingPolicy = JsonNamingPolicy.CamelCase, // CamelCase naming
};

string jsonString = JsonSerializer.Serialize(person, options);

Using Newtonsoft.Json

Add the NewtonsoftJson package and configure it in Startup.cs or Program.cs.

builder.Services.AddControllers()
    .AddNewtonsoftJson(options =>
    {
        options.SerializerSettings.Formatting = Newtonsoft.Json.Formatting.Indented;
    });

6. JSON File Handling

Reading JSON from a File:

using System.IO;
using System.Text.Json;

var jsonString = File.ReadAllText("person.json");
var person = JsonSerializer.Deserialize<Person>(jsonString);
Console.WriteLine($"Name: {person.Name}, Age: {person.Age}");

Writing JSON to a File:

using System.IO;
using System.Text.Json;

var person = new Person { Name = "John", Age = 30, City = "New York" };
string jsonString = JsonSerializer.Serialize(person);
File.WriteAllText("person.json", jsonString);

7. JSON Response Formatting

In ASP.NET Core, JSON response formatting can be configured in Program.cs.

builder.Services.AddControllers()
    .AddJsonOptions(options =>
    {
        options.JsonSerializerOptions.PropertyNamingPolicy = JsonNamingPolicy.CamelCase;
        options.JsonSerializerOptions.WriteIndented = true;
    });

This covers JSON handling in ASP.NET Core, including serialization, deserialization, file handling, and customization.

JSON in Ruby

In Ruby, handling JSON is straightforward thanks to the built-in json library. Here’s a comprehensive guide to working with JSON in Ruby:

1. JSON Basics

Loading the JSON Library

Ruby includes the json library in its standard library. To use it, you need to require it:

require 'json'

2. JSON Serialization (Convert Ruby Object to JSON)

Use JSON.generate or to_json (available after requiring json) to convert Ruby objects to JSON strings.

require 'json'

# Ruby hash
person = { name: "John", age: 30, city: "New York" }

# Convert Ruby hash to JSON string
json_string = JSON.generate(person)
puts json_string

# Alternative method using `to_json`
puts person.to_json

Output:

{"name":"John","age":30,"city":"New York"}

3. JSON Deserialization (Convert JSON to Ruby Object)

Use JSON.parse to convert JSON strings into Ruby objects (typically hashes).

require 'json'

# JSON string
json_string = '{"name":"Jane","age":25,"city":"Los Angeles"}'

# Parse JSON string to Ruby hash
person = JSON.parse(json_string)

puts person['name']  # Output: Jane
puts person['age']   # Output: 25
puts person['city']  # Output: Los Angeles

Default Behavior:

• JSON objects become Ruby hashes.
• JSON arrays become Ruby arrays.

4. Reading and Writing JSON Files

Write JSON to a File

require 'json'

person = { name: "Alice", age: 28, city: "Chicago" }

# Write JSON to a file
File.open("person.json", "w") do |file|
  file.write(JSON.pretty_generate(person)) # Pretty-print for readability
end

Read JSON from a File

require 'json'

# Read JSON from a file
json_data = File.read("person.json")
person = JSON.parse(json_data)

puts person['name']  # Output: Alice

5. Pretty-Printing JSON

Use JSON.pretty_generate to create a human-readable JSON string.

require 'json'

person = { name: "John", age: 30, city: "New York" }

# Pretty-print JSON
pretty_json = JSON.pretty_generate(person)
puts pretty_json

Output:

{
  "name": "John",
  "age": 30,
  "city": "New York"
}

6. Customizing JSON Serialization

You can define custom behavior for JSON serialization by overriding the to_json method in your Ruby classes.

require 'json'

class Person
  attr_accessor :name, :age, :city

  def initialize(name, age, city)
    @name = name
    @age = age
    @city = city
  end

  # Custom JSON serialization
  def to_json(*options)
    {
      name: @name,
      age: @age,
      city: @city
    }.to_json(*options)
  end
end

person = Person.new("John", 30, "New York")
puts person.to_json

Output:

{"name":"John","age":30,"city":"New York"}

7. Parsing JSON with Symbols as Keys

By default, JSON.parse uses strings as hash keys. To use symbols instead:

require 'json'

json_string = '{"name":"Jane","age":25,"city":"Los Angeles"}'

# Parse JSON with symbols as keys
person = JSON.parse(json_string, symbolize_names: true)

puts person[:name]  # Output: Jane

8. Handling Complex Data Structures

You can serialize and deserialize nested data structures like arrays and hashes.

require 'json'

# Nested Ruby structure
data = {
  people: [
    { name: "John", age: 30 },
    { name: "Jane", age: 25 }
  ]
}

# Serialize to JSON
json_string = JSON.generate(data)
puts json_string

# Deserialize JSON
parsed_data = JSON.parse(json_string)
puts parsed_data['people'][0]['name']  # Output: John

9. Error Handling

Always handle errors when parsing JSON to prevent crashes.

require 'json'

begin
  json_string = '{"name":"John", "age":30'
  person = JSON.parse(json_string)
rescue JSON::ParserError => e
  puts "Failed to parse JSON: #{e.message}"
end

Output:

Failed to parse JSON: 767: unexpected token at '{"name":"John", "age":30'

10. Common Methods

Why is JSON widely used?

• JSON is simple, clean, and looks like plain text. Developers can easily read and write JSON without special tools or training.
  Although it’s based on JavaScript syntax, it’s supported by almost every programming language (like Python, Java, Go, etc.).
• This makes it a great choice for data interchange between systems built with different tech stacks.
• JSON is less verbose than XML, meaning smaller payloads in APIs and faster transmission over the web.
• We can represent complex nested data (objects, arrays, strings, numbers, booleans, null) in a way that’s still easy to parse and manipulate.
• Most RESTful APIs use JSON to send and receive data because it’s easy to generate and consume by both clients (like browsers or mobile apps) and servers.
• Almost every modern tool, framework, or platform supports JSON natively or with minimal effort.
• We can quickly convert JSON to data structures in most programming languages using built-in methods (like JSON.parse() and JSON.stringify() in JavaScript).

Why JSON is so popular in 2025?

• Most web APIs (REST and even many GraphQL implementations) still use JSON as the default format.
• All major frameworks, databases, and platforms have first-class support for JSON (React, Node.js, Python, NoSQL DBs like MongoDB, etc.).
• Lightweight and faster to parse than XML or YAML, making it perfect for mobile and cloud-based apps.
• JSON works seamlessly in containerized environments, microservices, and serverless architectures.
• Modern frontend frameworks (React, Angular, Vue, Ember) love JSON data flows in and out of components in JSON format.
• Works smoothly across different platforms, languages, and systems.
• Easily transmitted over HTTPS, and used extensively in secure APIs and OAuth based systems.
• JSON is widely used for exchanging model data, configuration, and logging in AI, ML, and analytics workflows.

Conclusion

As we saw many technologies here we come to end with some good and some bad parts about is so same also happening with the JSON.

It also have its advantages and disadvantage, like if you except a quick and perfect response from the server then you can refer it, it has the wide range of schema supported with that but to use that we the device should be on the trusted network otherwise meanwhile it can make a problem for yourself only.

Censoring Censorship System in Python refers to the process of identifying and replacing offensive, inappropriate, or sensitive words or phrases in a text. This is often done to ensure that the content is suitable for various audiences, especially in applications like social media, forums, or chat platforms.

There are several ways to censor text in Content Censorship System in Python, including:

1. Using pre-defined word lists.
2. Using libraries that provide censorship functionality.
3. Machine learning models to detect offensive language.

If you’re looking for a Python package that handles text censorship, you can use profanity-check or better_profanity. These packages are designed to detect and censor profane or offensive language.

1. Using better_profanity

Installation:

pip install better_profanity

Usage:

from better_profanity import profanity

# Load a custom list of words (optional)
profanity.load_censor_words(["bad", "offensive"])

# Censor text
text = "This is some bad and offensive text."
censored_text = profanity.censor(text)

print("Original text:", text)
print("Censored text:", censored_text)

Output:

Original text: This is some bad and offensive text.
Censored text: This is some **** and ******** text.

2. Using profanity-check

Installation

pip install profanity-check

Usage

from profanity_check import predict, predict_prob

text = "This is a bad text."
texts = ["This is fine.", "This is offensive."]

# Predict if a text is offensive (1 = offensive, 0 = not offensive)
print(predict([text]))

# Predict the probability of being offensive
print(predict_prob(texts))

profanity-check is more suited for detecting profane or offensive language, rather than replacing it with censored text.

Which One to Use?

• Use better_profanity if you want a simple and customizable censoring tool.
• Use profanity-check if you need a machine-learning-based approach to detect offensive content.

Here’s an example of how to create a Flask API that uses both better_profanity for censoring text and profanity-check for detecting offensive language in content censorship system.

Install the required libraries

pip install flask better_profanity profanity-check

Flask API Code

from flask import Flask, request, jsonify
from better_profanity import profanity
from profanity_check import predict, predict_prob

app = Flask(__name__)

# Load custom censor words for better_profanity (optional)
profanity.load_censor_words(["bad", "offensive"])

@app.route("/censor", methods=["POST"])
def censor_text():
    """
    API endpoint to censor offensive words in a given text.
    """
    data = request.json
    text = data.get("text", "")
    censored_text = profanity.censor(text)
    return jsonify({"original_text": text, "censored_text": censored_text})

@app.route("/detect", methods=["POST"])
def detect_offensive():
    """
    API endpoint to detect if text contains offensive content.
    """
    data = request.json
    text = data.get("text", "")
    
    # Predict offensive probability
    is_offensive = predict([text])[0]  # 1 for offensive, 0 for not offensive
    offensive_prob = predict_prob([text])[0]
    
    return jsonify({
        "text": text,
        "is_offensive": bool(is_offensive),
        "offensive_probability": offensive_prob
    })

if __name__ == "__main__":
    app.run(debug=True)

Endpoints

Censor Offensive Words (better_profanity)

URL:/censor
Method: POST
Request Body (JSON):

{
  "text": "This is some bad and offensive text."
}

Request Body (JSON):

{
  "original_text": "This is some bad and offensive text.",
  "censored_text": "This is some **** and ******** text."
}

Detect Offensive Text (profanity-check)

URL: /detect
Method: POST
Request Body (JSON):

{
  "text": "This is some offensive text."
}

Request Body (JSON):

{
  "text": "This is some offensive text.",
  "is_offensive": true,
  "offensive_probability": 0.85
}

Content Censorship System in Node.js

In Node.js, censoring text involves identifying and replacing offensive or inappropriate words with a placeholder (e.g., *). There are several approaches to implement text censorship, including using word lists, regular expressions, and third-party libraries.

Here’s a breakdown of the methods for censoring text in Node.js:

1. Manual Censorship with Word Lists

One of the simplest methods is to maintain a list of offensive words and replace them with symbols like *. This can be done by using basic string replacement or regular expressions.

function censorText(text, badWords) {
    badWords.forEach(word => {
        const regex = new RegExp(`\\b${word}\\b`, 'gi');
        text = text.replace(regex, '*'.repeat(word.length));
    });
    return text;
}

const badWords = ['bad', 'offensive', 'ugly'];
const inputText = 'This is a bad and offensive sentence.';
const censoredText = censorText(inputText, badWords);

console.log(censoredText);

Output:

This is a *** and ******** sentence.

2. Using a Third-Party Library (bad-words)

You can use a library like bad-words to censor offensive words in a text. This library provides a list of common offensive words and allows you to easily censor them.

Installation:

npm install bad-words

Example:

const Filter = require('bad-words');
const filter = new Filter();

const text = 'This is a bad example of offensive content.';
const censoredText = filter.clean(text);

console.log(censoredText);

Output:

This is a *** example of ****** content.

You can also customize the list of words the filter uses by adding your own:

filter.addWords('bad', 'offensive', 'ugly');

3. Using Regular Expressions

For more flexibility, you can use regular expressions in Node.js to match and replace offensive words.

function censorWithRegex(text, badWords) {
    badWords.forEach(word => {
        const regex = new RegExp(`\\b${word}\\b`, 'gi');
        text = text.replace(regex, '*'.repeat(word.length));
    });
    return text;
}

const badWords = ['bad', 'ugly'];
const text = 'This is a bad example of ugly content.';
const censoredText = censorWithRegex(text, badWords);

console.log(censoredText);

Output:

This is a *** example of *** content.

4. Using profanity-check in Node.js

There is a Node.js package called profanity-check that uses machine learning to detect offensive content. You can use it to identify offensive text and respond accordingly.

Installation:

npm install profanity-check

Example:

const { check } = require('profanity-check');

const text = 'This is a bad sentence.';
const isOffensive = check(text);

if (isOffensive) {
    console.log('This text is offensive');
} else {
    console.log('This text is not offensive');
}

Output:

This text is offensive

5. Express.js API for Censorship

You can build an API in Node.js using express to allow users to send text and get censored responses.

Install the necessary packages:

npm install express bad-words

Create the server:

const express = require('express');
const Filter = require('bad-words');
const app = express();
const filter = new Filter();

app.use(express.json());

app.post('/censor', (req, res) => {
    const { text } = req.body;
    const censoredText = filter.clean(text);
    res.json({ originalText: text, censoredText });
});

app.listen(3000, () => {
    console.log('Server is running on port 3000');
});

Test the API

You can use Postman or curl to test the API. Send a POST request with the JSON body containing the text field.

Response:

{
  "originalText": "This is a bad sentence",
  "censoredText": "This is a *** sentence"
}

Conclusion

In an age where digital content spreads rapidly across platforms, the need for effective regulation and responsible sharing has never been greater. A well-implemented Content Censorship System plays a vital role in maintaining ethical standards, protecting vulnerable audiences, and ensuring compliance with regional laws and community guidelines.

By adopting a robust Content Censorship System, governments, organizations, and digital platforms can strike a balance between freedom of expression and the need to prevent harmful or inappropriate content. As technology continues to evolve, so must the mechanisms we use to monitor and manage digital information. A proactive approach to content moderation ensures safer and more respectful online spaces for everyone.

Good Parts of AngularJS JavaScript Framework

1. MVC Compatibility (or MVVM or MVP or MVW)

There is a debate on Google+ by Igor Minar (Lead of AngularJS) post in the AngularJS forum, deciding to call Angular an MVW framework: Model – View – Whatever!

I’d rather see developers build kick-ass apps that are well-designed and follow separation of concerns than see them waste time arguing about MV* nonsense. And for this reason, I hereby declare AngularJS to be MVW framework – Model-View-Whatever. Where Whatever stands for “whatever works for you”.
— Igor Minar

In another world, AngularJS JavaScript Framework is MVC Compatibility and does not require writing lengthy code to connect the MVC components of the apps, which saves them lots of time and effort. Just make the modules of your applications and rest of your work will do the Angular by managing the components and also connecting them all by itself.

2. Two Way Data binding

AngularJS comes with the great feature called as data binding which reduces the coding at very a smaller number of lines.

Data binding tries to get rid of writing the codes multiple times by doing the work on backend server from creating the multiple executions of the same codes. Data binding removes the dependency on manually accessing the values.

<div ng-app>
First Name:
<input type="text" ng-model="firstName"/>
Last Name:
<input type="text" ng-model="lastName"/>
<div>Hello {{ firstName + " " + lastName }}!</div>
</div>

<div ng-app="" ng-init="student={firstName:'Rajeev',lastName:'Sharma'}">
<div>The name is <span ng-bind="student.lastName"></span></div>
</div>

3. Dependency injection

It’s nothing new in the back-end development world but in the JavaScript world, it’s painful been slow to become a part of our coding workflows.

AngularJS handles a Duplicate injection at the great level. We will try to illustrate the same with the dependent objects 500 times because we think JavaScript is not same as structured complex backend application.

angular.module('ccn-main.controllers',[]).controller('LoginController', ['$scope', 'loginService', function($scope , loginService) {
// Login functionality
}])

This allows you to serve the libraries to be used in the development phase.

4. DOM Manipulation

AngularJS keeps DOM manipulation inside the directives and not in the views part also code does not come in the controller part Like:

app.directive('focusInput', function($timeout) {
   return {
      link: function(scope, element, attrs) {
        element.bind('click', function() {
           $timeout(function() {
              element.parent().parent().find('input')[0].focus();
           });
        });
      }
    };
});

5. Testability

AngularJS Framework builds with Unit testing ready because it uses dependency injection. Angular provides separately application logic from the DOM manipulations, making testing a lot easier.

It is a really, really good idea to regard app testing as equal in importance to app writing. The testing difficulty is dramatically affected by the way the code is structured.

— The Zen of Angular

6. Dynamic Templates and Supports Single Page Applications:

According to AngularJS official document there is 4 types of element and attributes support by AngularJS is Directive, Markup, Filter, Form controls.

Which makes it the very strong framework to support HTML template system that helps to work design and developer separately on the same system. In simple app, the consist of HTML and CSS and complex app you can use the ngView directive to load partials based on configuration passed to the $route service

Bad Parts of AngularJS JavaScript Framework (version 1.x)

1. Parameter name-based dependency injection:

Angular has a built-in dependency injector that will pass appropriate objects to your function based on the names of its parameters.

function myController($scope, $window) {
// ...
}

2. Difficult to adapt the existing code

With AngularJS you can’t reuse the existing code it gives the error immediately if you will try to use the code again in the program. So, it requires some developers who can work on it to extend its features in so that we can use the code again which existing in the programme.

3.Too Heavy framework

AngularJS JavaScript Framework is very heavy and bulky framework that might be a good option to make the large-scale application. But in case of simpler requirements of data binding, it will require a little too much effort to extract its features and using those features because it can sometimes confuse them with the excess of functionality that might be totally useless.

4.Robust Framework

AngularJS is a very Robust and viable framework for building the web apps. Whether it lives up to the expectations of being the most dominant JavaScript framework for web development is yet to be decided and seen.

Conclusion

As we saw the many pros and cons of the AngularJS in the development, so it lastly depends on you that which feature you have to select of AngularJS JavaScript Framework in the development.

Because to make the robust applications then it will be difficult to use the AngularJS but to make the application MVC compatible and dependency management then you could use the Angular.

There are many web frameworks today that all are approaching or have had any major new releases. Recently, EmberJS Javascript Framework released 6.3.0 (17 March 2025) just less than two months ago by simply making it a stealthily easy upgrade from its previous version.

Also, just a couple weeks ago REACT and Angular new ones, which is a major step on its march to 1.0. But most popular have been the ‘Ember’.

EmberJS Javascript Framework

Those who know a bit about Ember know that the ‘Ember’ is actually a framework that can position itself as the basic and important framework for any ambitious projects to be done.

Some apps that have been built with Ember actually include many of Apple’s properties too, like Discourse which is a new take on forums by Jeff Atwood and Ghost which is a modern blogging engine which is very popular.

Also, Ember is driven by two legendary hardworking software engineers in the prime industry, Yehuda Katz, and Tom Dale, who are big names in their fields of work.

Unlike any other framework that is discussed or used, the Ember is actually not built by a known mega-corporation.

Rather starting from the base, it undoubtedly does have an amazing, progressing, passionate, and large active community around it working each day towards its betterment. And because it is becoming popular, Ember js. has seen quite a development in India.

However, Prior to 1.0, Ember had actually grown notorious for its changing API’s as they had discovered the important views as to where they really wanted to take the framework.

Afterward, however, to the credit of the team working on it, they’ve absolutely proven themselves much capable of finally making large underlying changes while only gradually changing the user-facing parts that are revolutionary.

They have also taken this approach with the very release that was earlier this year of the Glimmer, and also a very high-speed rendering engine. And with 2.0, they also have now removed the deprecated parts that also couldn’t take advantage of this new engine. Any app that runs with Ember 2.X now actually will fly and run with smoothness.

What’s lies in the future of version 2.X?

When the further adoption of ES2015 features like modules, or multiple classes, and even the decorators shall be introduced, no one shall be able to compete with the Ember.

Also, the Ember.js development in India has also expanded with time. The ember development definitely has seen quite a scale up in India. Also, along with it, a departure from the Mustache templating and also, the use of bracket syntax for components shall be introduced very soon too.

However, a change to the project layout structure is what also lies ahead on future to what are called pods—so instead of just grouping by the function like controllers, or models, components, etc., we shall now also witness the very best top levels that will be present soon in the future.

Also, the controllers are thought to be removed in favor of the routable components, new models of which shall be newly introduced. All these shall be really good for the development of Ember in India.

Also, the advancement of their server-side renderer shall be existing very soon so as to help reduce the page load times and along with it, improve the search engine optimization too.

How is an Ember.js application organized?

Before we get to composing the application, then what about the investigation, how it is organized on the filesystem? The “Ember” command is able to create an entire directory structure on your computer. Seeing these are imperative to proficiently work with the apparatus and make astonishing ventures.

See below directory structure of ember.js version 3.1.0 using latest project development with Laravel PHP Framework.

At the exceptionally top level you will see the accompanying documents and catalogs:

• md – This is the standard readme record portraying the application
• json – This is the standard npm arrangement document portraying your application. This is utilized essentially for the conditions to be introduced effectively.
• coal cli-build.js – This is the arrangement for the Ember CLI instrument to control our construct
• js – This is the arrangement for the test system. This enables you to characterize, in addition to other things, the programs that ought to be utilized to run the tests in for various situations.
• application/ – This is the real application rationale. A considerable measure occurs in here that will be secured underneath.
• config/ – This is the design of the application
• config/targets.js – This is a rundown of programs to help. This is utilized by Babel to guarantee that the Javascript is transpired such that they will all work.
• config/environment.js – This is the fundamental setup for your application. Anything that is required for the application, yet that may fluctuate starting with one condition then onto the next, ought to be placed in here.
• open/ – This is any static assets that you wish to incorporate into your application. For instance, pictures and textual styles.
• seller/ – This is the place any frontend conditions that are not overseen by the fabricate framework go.
• tests/ – This is the place the greater part of the tests go

Who should use EmberJS?

Now the question lies, who should be making use of Ember? Ember actually makes a great choice for all the writing web apps.

As also discussed above, many ambitious apps are also built just by using this simple and efficient framework. It also has been very particularly well received by the Ruby Community and also including our own Ruby devs at Smashing Boxes. And if you happen to be a Ruby shop, Ember is one fantastic choice to go with.

A ton of documentation, articles, and blogs and much more exist simply just by combining these two technologies.

It is often that we waste time into discovering, or researching, and gluing together libraries that actually don’t mesh very well. So,  ember makes so many decisions for you, which thus provides surprising value.

There are multiple pros and cons to both of these approaches, but also those who want everything to just work well together will definitely love Ember.

Also, you can Hire EmberJs Framework Developer for multiple quick solutions.

For example, you can simply hire EmberJS Framework developer from like the Ember js.the company in India like the Bacancy to get the best web application development services.

The developers shall bear immense experience too in the multiple languages that are used in ember such as the JavaScript, CSS, AngularJS, jQuery, etc, to simply develop rich and user-friendly web applications. So it’s a good option to hire Ember Js. developers.

Comparing EmberJS

Of all other frameworks like Angular or React, Ember was actually the quickest to get something really started. Immediately you also have a web server that actually reloads the page on changes and also the best practices just right out of the box.

With the other two, you might be actually spending time configuring the Webpack or the Gulp to just get a project off the ground. And with it, you might fiddle with how you really want the project simply laid out.

Or you also might spend time searching just for a boilerplate project to be copied or to copy. So the virtue of simply being opinionated, Ember just removes all that friction and so is best to use.

EmberJS 3.0

Is EmberJS dead in 2025?

As of April 2025, Ember.js is not dead. While it may not be as widely adopted as frameworks like React or Vue.js, Ember.js continues to be maintained and used for building ambitious web applications. The Ember.js team actively supports Long Term Support (LTS) releases, which receive bug fixes and security updates for extended periods.

Despite its ongoing support, Ember.js has a smaller user base compared to other JavaScript frameworks. This is partly due to its steeper learning curve and its suitability for larger, more complex applications, which may not align with every project’s needs. However, for developers working on large-scale applications that benefit from its conventions and tooling, Ember.js remains a viable and supported choice.

As the digital world continues to expand, ensuring user safety has become a paramount concern for online platforms. Inappropriate or explicit content, often categorized as Not Safe for Work (NSFW), poses significant challenges for maintaining a healthy online environment. This article explores cutting-edge NSFW detection techniques and strategies that platforms can adopt to build safer digital communities.

The Importance of NSFW Content Solutions

The proliferation of user-generated content has made it increasingly difficult to monitor and moderate online spaces. NSFW content can harm users, tarnish brand reputations, and violate legal or community guidelines. Implementing effective content moderation systems is essential to:

• Protect Users: Safeguard individuals, especially minors, from harmful or explicit material.
• Maintain Brand Integrity: Ensure platform credibility by providing a safe user experience.
• Comply with Regulations: Adhere to legal requirements for content moderation, such as GDPR and COPPA.

Advanced NSFW Detection Techniques

Modern NSFW detection relies heavily on AI and machine learning to identify and filter explicit content. Here are some of the most effective techniques:

1. Deep Learning Models

Convolutional Neural Networks (CNNs) and other deep learning architectures are highly effective for analyzing images and videos. These models can:

• Detect nudity, explicit imagery, or inappropriate gestures.
• Analyze video frames for consistent filtering of explicit content.

2. Natural Language Processing (NLP)

For text-based content, NLP algorithms can identify:

• Offensive language or slurs.
• Contextually inappropriate content, such as harmful jokes or suggestive text.

3. Multi-Modal Detection

Combining image, video, and text analysis ensures a comprehensive approach to content moderation. AI systems can cross-reference multiple data types for improved accuracy.

4. Customizable Thresholds

Platforms can set sensitivity levels to balance over- and under-moderation. This flexibility allows for tailored solutions that align with community standards.

Best Practices for NSFW Content Moderation

To create a robust moderation framework, platforms should consider the following strategies:

1. Implement Real-Time Moderation

Use AI-powered tools for real-time detection and removal of NSFW content. This ensures harmful material is addressed before it reaches a wider audience.

2. Human-in-the-Loop Systems

Combine AI with human moderators to handle edge cases and ensure context-sensitive decisions. Humans can provide oversight for ambiguous content flagged by AI.

3. Transparent Community Guidelines

Clearly define and communicate acceptable content standards to users. Transparency fosters trust and encourages responsible behavior.

4. Regular Model Updates

AI models must be updated regularly to stay effective against evolving trends and adversarial tactics, such as content designed to evade detection.

5. Invest in User Reporting Tools

Allow users to flag inappropriate content. User feedback can enhance AI training and provide additional moderation insights.

Challenges in NSFW Detection

Despite advancements, NSFW detection faces several obstacles:

• False Positives and Negatives: Balancing precision and recall remains a challenge for AI models.
• Cultural Differences: Standards for explicit content vary globally, complicating detection algorithms.
• Adversarial Content: Malicious actors may manipulate content to bypass detection systems.

Addressing these challenges requires a combination of technical innovation, human oversight, and user engagement.

Building a Safer Digital Future with NSFW Content Solutions

Effective NSFW detection and content moderation are critical for fostering safer digital spaces. By leveraging advanced AI technologies, transparent guidelines, and user collaboration, platforms can mitigate the risks associated with explicit content.

As the digital landscape evolves, so too must our strategies for ensuring online safety. The future of content moderation lies in the seamless integration of technology and human empathy creating communities that are not only safe but also welcoming and inclusive.

NSFWJS with TensorflowJS

Key Features:

1. Image Classification:
   • The /image endpoint processes an image file and classifies it for NSFW content.
   • It uses sharp to resize and optimize the image before passing it to the TensorFlow model.
   • The NSFW classification model predicts and returns the classifications.
2. Video Frame Classification:
   • The /video endpoint processes a video file, extracts frames at 1 frame per second using ffmpeg, and classifies each frame for NSFW content.
   • Extracted frames are temporarily saved, processed, and then deleted to save disk space.
3. TensorFlow and NSFW.js:
   • The nsfwjs library is used with TensorFlow.js to load the pre-trained NSFW model (InceptionV3).
4. File Handling:
   • Uses fs and path modules to manage files.
   • multer is included for handling file uploads, though it’s not currently utilized directly for image or video upload.
5. Error Handling:
   • Includes basic error handling and responds with appropriate status codes and messages.

Setup:

1. Download Install ffmpeg package for convert video into images.

2. Clone the nswfjs git repo and clone the code in project folder.

3. Run the npm install command inside project folder to install the npm packages.

4. We need to install following other packages to make it work in nodejs with expressjs framework.

npm install sharp fluent-ffmpeg axios

5. Create server.js and add following complete code and run using node server.js on terminal.

The growth and development of unique frameworks having different features and characteristics are rising and growing nowadays.

No one can deny the importance and features offered by JavaScript framework to its users. Developers of the technology and framework stating that the golden period of the technological era has begun, and the time has gone for the traditional and outdated libraries.

Amongst all of these things, the question still clicks the mind is that which is the best JavaScript framework in 2025 to use, everybody, want to know the relevant answer of this.

We know that there are too many choices for the libraries we have, the most important factor is to know your needs and then go for the best suitable match.

Libraries or Framework

We can say that these terms are the same and interchangeable. People use one in place of other. In layman or we can say it in simple words that both library and framework are codes of JavaScript, the only contrast they have in their functionality.

If we talk about a framework then we can understand it as a platform that allows developers to customize and modify the codes within the website/app/software in accordance with the rules of that framework.

On the other hand, libraries offer you with the functional features that can be used directly while scripting.

In this writing, we are going to elaborate on “react” a JavaScript framework that is used for different purposes and provides different functional features to its users. Let’s start a journey to know “react.js” and react popularity graph.

ReactJS Popularity

React.js, It is not a full-fledged framework but it is a library developed by Facebook. The integration of the User-Interface library into an MVC framework does not need very deep knowledge of programming.

It is an open source library based on JavaScript used for developing feature-rich web applications efficiently and fast with the minimal coding task.

React has created an impact on both developers and designers, and it has made complex integration a bit easier by its feature-rich library.

It allows programmers to create encapsulated components that handle their own state and after that, these are written to make a complex UI.

Due to its many features, for example, lazy loading has been implemented successfully on a very big scale. By using React Starter-kit and React Boilerplate it has become very easy to develop more interactive interfaces.

JavaScript has more features and power than HTML so the basic idea behind React is to put HTML in JavaScript not vice-versa.

Core Objective

The main objective of react.js is giving the high rendering performance. It breaks the working requirements on the entire web application because it allows developers to break the complex UI into easier components. By this point, we can understand that its power is based on its individual components.

Uses of React.JS and reasons behind its popularity

There are many reasons behind react popularity. One of the reasons we can say that it is getting love and unparalleled support from the community of JavaScript developers. Before its development by Facebook, most of the developers were forced to do lots of coding.

Developers and designers utilizing different frameworks have the test of reworking on most codes even while making components that changed rapidly.

What they needed was a framework that could enable them to break down typical components and make the reuse of the codes in order to complete their projects quicker.

Features of React.js

1. One-way Data Binding:

   When we talk about one-way data binding, React JS come in the role. It means that it allows us to direct the data flow in one direction only.

2. Virtual DOM:

   It developers its own virtual DOM in order to keep your components at this place which offer high performance and flexibility to the developers. In this way, it saves you from the costly DOM operations and gives you updates in a very effective way.

React.JS provides the solutions desired by the developers or we can say that it has given the solution that developers were searching for.

It utilizes JSX (an unmatched syntax that permits HTML tag and HTML quotes app for rendering particular subcomponents).

It is very helpful when it is a matter of compounding components and construction of machine-readable codes into a single-time verifiable file.

Today, most developers choose React.js due to its extra flexibility and simplicity. Many of them recommending it as the new way and future of web development. According to estimation, more than 94,000 sites use React.js.

One of the main reasons for its popularity among big corporations such as Instagram, Uber, Facebook, PayPal and others is that it helps to solve complex issued related to user interface. Its credibility is also one of the best features makes it a popular framework among its users.

There are many more reasons behind the popularity of React.js. Let’s check them:

1. It solves a genuine issue:

Developing big array strings of HTML utilizing simple JavaScript includes complex code. Templating engines can be limiting when we talk about HTML markup generated by them.

Creating dynamic web applications is quite easier with it. When you don’t want to use a framework like Angular, but needs to have the presence of JavaScript interface to use plenty of components.

React has changed all of this. With React and JSX, it seems similarly HTML Templating is the top in React web app.

It solves the issues in the very easy way, by utilizing common JavaScript, JSX which is very similar to HTML.

2. A healthy and increasing ecosystem and community:

Technology is increasing with the growth of technical communities. You can easily get a library without developing it. When you look at NPM it is easy to get many packages that will provide you to act with React to develop something unique.

3. Broaden the area of thinking:

Now we know that it is easy to solve complex problems with React because we break the complex interfaces into atomic and small components.

So, if you are thinking to build a big and complex UI then it is not a big issue. You need just to hire the react.js developer in India who can help you to connect with your desired interface into your application.

4. Flexibility:

The developers have presented the key idea of state and flux, but they also permit to use your application in a way you need it to manage state.

It’s just a little task, but by going through with the various methods to solve the issues in a React application, it is easy to make an informed and firm decision about the best suitable system you want to use.

5. It is really cool:

Yes. It is right to say that react is really cool. You can complete the elevated expectations of the technology. React.js is very productive when we talk about creating complex UI. It is true that React.js is not a solution for all the issues but help developers when they template out HTML inside JavaScript.

6. It is fun to use:

React allows us to develop user interfaces by using components when there is no way to escape except developing complex UI.

React makes the code enjoyable to write and easy to understand because it involves minimal side effects and also it is declarative.

7. The future of ReactJS:

The ReactJS and Facebook team have shown the promise of upgrading ReactJS efficiency. This is pivotal to whether the quick developing competition from different systems, for example, Vue.js. A portion of the things to expect in future releases incorporate;

Designers are likewise expecting enhancements in the error handling feature. In the previous time, while rendering cases of runtime errors regularly put react.js in an unbalanced broken state.

This needs page refreshing regularly. The present model of showing the error is tossing it inside the lifecycle methods or the component.

In spite of the fact that this stop rendering undesired and corrupted data, it isn’t a good thought for better UX.

ReactJS fans should expect new render kinds. For instance, the ReactJS team is probably going to add unique feature fragment syntax to the JSX after this there will be no need of keys.

Improving rendering at server-side. Though the latest and updated React.JS accompanies a completely modified server render which makes it ideal and very fast for streaming, it is an extraordinary place to pitch upgrades.

ReactJS was developed to help enhance the aggregate rendered pages from the site server. Besides, to render on the client-side it utilizes nodes. Having the ability to alter built tooling and even scale back on maintenance budgets makes ReactJS very productive.

Comparison with other frameworks

Really there is no doubt that it is a very popular framework and the developer’s first choice in the present time, but we also have other popular frameworks. Let’s start the comparison between React and other frameworks.

The learning step:

If you are new to the development field then you can easily start with React.js because it is easy to learn it if compared to Angular and with other frameworks. You need to have the familiarity with HTML and JavaScript while starting with ReactJS. On the other hand, if you want to learn frameworks like Angular then it is a lengthy procedure that needs many concepts to learn. It is not easy to start with Angular for a less experienced developer as compared to ReactJS.

CSS and HTML application:

It is JS inside ReactJS. Every HTML component and structure is shown via JSX when the CSS management and latest trends inside JavaScript as well.

Runtime performance:

When we talk about speed then Reach Js and VueJS are exceptional and unique. While talking about ReactJS every time a render is triggered, a component changes for the complete sub-tree of components.

If re-rendering is not your requirement, then use PureComponents. While talking about VueJS it (components’ dependencies) is handled automatically at the time of rendering.

It means that there is no need to tell the system about the component that needs re-rendering after the state changes.

If we compare the performance of ReactJS with Angular, ReactJS provides better performance. Angular is relatively slow and at the time when a user triggers an update, its digest cycle needs multiple times running before stabilizing. This is not an issue in case of ReactJS because it has a unique system of dependency tracking that utilizes a sync queuing.

Now with the points of comparison we have, it is true that React is a stronger framework because it breaks down the complex UI and helps developers to work on different components. However, it is closely followed by the Vue.js framework.

Why is ReactJS good for businesses (React.js popularity)?

We know that the present era is touch-driven, the developers and business owners are ever seeking for better techniques for providing businesses with a good and big advantage.

One awesome innovation for helping businesses to exceed their rivals while making web applications is ReactJS. It allows businesses to design apps with a better UI in order to improve the user experience.

If you need a better technology for higher click-through-rates, user engagement and conversions then ReactJS is the best for you.

Use it for the assured results and performance than other frameworks provide. It restricts to update DOM, it tends that the applications will deliver better UX in the fastest way.

Why is it recommended to use ReactJS?

It helps developers to design their apps and write codes within JS. It’s one of the best features is JSX that make it fun and easy too.

It is easy to make new UI features and check it in real time. When you want to take HTML into JS directly then it helps you. As, it is already stated, that it helps developers to break down complex UI into components.

This idea makes ReactJS unique and different from other frameworks. It is helpful in making complex UI and more intuitive designs.

React.js helps to populate components using custom data. It helps to pass custom data to a particular UI component.

With state (a single location where developers save the content that can change amid app), single web app turns out to be very simple due to all the details are saved and sources from one component.

It is very fast due to Virtual DOM. A random reply is very necessary to enhance the user experience and it depends on UI.

At the point when ReactJS was developed, the developers appropriately predicted that updating old HTML would turn out to be additional expensive and crucial.

So, the key idea of Virtual DOM assists ReactJS to know when it is right time to re-render or when it is correct to ignore some particular pieces of DOM since it can identify the time of data change.

In the Last Words

It is very necessary to hire an experienced and professional company to get your desired web app based on ReactJS technology.

Always hire the best professionals for a great success and to be a step ahead in the competitive era. So, to hit the competition, to get raising conversion rates, cutting on costs, to accelerate growth, to achieve goals, and to give the best user experience you should choose ReactJS.

React.js is more popular with PHP Development Companies in India, You can hire 4 years of experience react.js developer in 20 USD/ Hour or 1500 USD/ Month cost.

Jade is specially designed for the server side template in Node.js but it can be used in many other environments also. It’s used to produce XML documents like (HTML, RSS etc.), so we can’t use it to create the plain text like HTML/CSS other documents.

Jade Template Engine is used to make the template more beautiful and more meaningful with the help of description and their layout. So, what are the advantages we can take from the Jade we will try to find out? major in that which are listed below:

1. Re-usable Function:

You can compile your template into the reusable function which can be run on server or client side both. If you want to send the same template again then you just have to write some line of code of the re-usable function and then you have to just run the template in that function and then you can set the different data sets in that and you can send it for the rendering demand.

2. Template inheritance:

Jade has great support towards the Template inheritance. It means that it helps in managing templates that resemble object-oriented programming techniques.

With this, you can inherit the contents of one template into another same like as class. Template inheritance keeps the template management minimal and efficient so we can improve quality of the template on both sides.

3. Template Productivity:

As Jade template engine comes with the many handling modules so final result output comes in a great way in look and feel.

Problems like output encoding, iterating conditions, and error handling come in Jade so it helps in a good productivity of the templates than other template engines.

4. Code Organization:

The presentation is the important thing in any field, if your presentation is in a nice way then it will be clearly understandable to anyone but if your presentation is not good then no can understand it. It will work as miserable.

Jade gives the nice way to the data manipulation and their representation. By this templates, you can easily understand what is data and which part is for presentation. So, it also helps the server side script also to the client.

5. Supported by many technologies:

You can implement the Jade in the language of your project which you making. Jade Template Engine can be implemented with the PHP, Scala, Ruby, Python, and java etc. languages so with such a wide language support everyone want to use Jade for the template presentation and its data manipulation.

6. No closing tags:

Jade is most famous for the self-closing tags which other languages do not include, Means tags such as img, meta, link explicitly self-close a tag by simply appending the / character. It is the most famous part of the Jade which people in the technological world liking it and most appreciable thing in the market.

foo/
foo(bar='baz')/
/*----Output----*/
<foo/>
<foo bar="baz"/>

7. Master Template:

As the name Says “Master” it means that there will be one master template which will come on every page. You can create the master layout for your web-page and include different blocks of the content in the body for the individual section or part particular pages.

1. WordPress uses the jQuery Javascript library in the admin pages. In fact, you will find the jQuery files in the “wp-includes/js/jquery” directory.
2. WordPress has built-in support for the jQuery library. The wp enqueue script function has a list of supported jQuery libraries and widgets but none for MooTools.
3. Some of my favorite WordPress plugins like the NextGen gallery use jQuery so I have to load the jQuery library on my website.
4. I didn’t want to have 2 different Javascript libraries on my website because it would increase the loading time of my pages.
5. I found better and simpler jQuery scripts to replace MooTabs and SmoothGallery on my website.

Since jQuery is so well integrated into the WordPress platform, I don’t wish to reinvent the wheel and use MooTools on top of jQuery.

I found this on another’s blogs explaining the differences between jQuery and MooTools:

Mootools :

“MooTools is aimed more at JavaScript developers, while jQuery is more for people who want to implement JavaScript functionality in the easiest possible way.”

JQuery :

“jQuery is for people who aren’t necessarily interested in delving deep into JavaScript while MooTools provides an object-oriented framework for hardcore JavaScript development. This is why most people find MooTools harder to use in comparison to jQuery.”

As a web developer, I personally find jQuery a lot easier to work with than MooTools. It really makes coding in Javascript and creating cool effects a lot easier.

jQuery suits my needs better than MooTools because I only use it to create some special effects on websites and I have no desire or need to learn very advanced Javascript.

If you go to the jQuery site, here’s what it says at the top of the page:

“jQuery is a fast and concise JavaScript Library that simplifies HTML document traversing, event handling, animating, and Ajax interactions for rapid web development. jQuery is designed to change the way that you write JavaScript.”

…and if you go to MooTools, this is what you’ll find:

“MooTools is a compact, modular, Object-Oriented JavaScript framework designed for the intermediate to advanced JavaScript developer. It allows you to write powerful, flexible, and cross-browser code with its elegant, well documented, and coherent API.”
