Explanation

A server framework is a software framework used to build backend or server-side applications. It provides built-in tools for handling HTTP requests, routing URLs, managing middleware, connecting to databases, authentication, and building APIs, making backend development faster and more structured.

Code Example

Examples of Server Frameworks: Express.js 
(Node.js), Spring Boot (Java), 
Django (Python), Flask (Python), 
Laravel (PHP)

Explanation

Server frameworks are used to simplify backend development. They provide ready-made features like #white-routing #white-request handling, #white-middleware support, #white-authentication #white-database integration.

Code Example

Without a framework, 
developers would need 
to build these features from scratch. 
Using a server framework helps 
write cleaner code
speeds up development
easier to maintain

Explanation

Express.js is a popular Node.js server framework used to build APIs and web applications. It provides simple routing and middleware support.

Code Example

const express = require('express');
const app = express();

app.get('/', (req, res) => {
  res.send('Hello from Express server');
});

app.listen(3000);

@RestController

  @GetMapping("/hello")
  public String hello() {
    return "Hello from Spring Boot";
  }
}

Explanation

Flask is a lightweight Python server framework used for building web applications and APIs quickly.

Code Example

from flask import Flask
app = Flask(__name__)

@app.route('/')
def hello():
    return 'Hello from Flask'

app.run()

Code Example

from django.http import HttpResponse

def hello(request):
    return HttpResponse('Hello from Django')
