Top 10 Backend Frameworks Every Developer Should Know

Introduction

In the world of web development, the backend plays a crucial role in powering the logic, data storage, and functionality of websites and applications. Backend frameworks provide developers with a structured and efficient way to build robust and scalable applications. Choosing the right framework can significantly impact the development process, performance, and maintainability of your project.

This article explores the top 10 backend frameworks that every developer should be familiar with. We will delve into their key features, benefits, use cases, and provide examples to illustrate their capabilities.

const port = 3000;

const server = http.createServer((req, res) => {

  res.statusCode = 200;

  res.setHeader('Content-Type', 'text/plain');

  res.end('Hello, World!\n');

});

server.listen(port, hostname, () => {

  console.log(Server running at http://${hostname}:${port}/);

});

@SpringBootApplication
@RestController
public class Application {

@GetMapping("/")
public String home() {
    return "Hello, world!";
}

public static void main(String[] args) {
    SpringApplication.run(Application.class, args);
}

}

Express.js (JavaScript)
