Top 5 Node.js Backend Frameworks to Master in 2024

Since 2009 Node.js has attracted attention, and most backend developers prefer it. Its popularity has risen due to reduced load times and performance improvements, making it essential to analyze the top 5 Node.js backend frameworks in 2024.

Express.js: The battle‑tested champion

Express.js is one of the most famous Node.js backend frameworks. It is an open‑source web application framework built on the Node.js platform and is free. Its lightweight nature makes it popular among both beginners and experienced developers for creating web applications and RESTful APIs.

Key features: What makes it unique?

Efficient routing management – Express provides a concise way to handle HTTP requests and assign them to tasks.

// app.js
const express = require('express');
const app = express();
const port = 3000;

// Route for Homepage
app.get('/', (req, res) => {
  res.send('Welcome to the homepage!');
});

// Route 2
app.get('/user/:id', (req, res) => {
  const userId = req.params.id;
  res.send(User Profile Page - ID: ${userId} );
});

Middleware support – Allows using middleware to process HTTP requests.

const express = require('express');
const app = express();
const port = 3000;

app.use((req, res, next) => {
  console.log([${new Date().toLocaleString()}] ${req.method} ${req.url} );
  next();
});

Simple database integration – Database‑agnostic, developers can choose any database.

Easy to learn – Minimalist design makes it easy for developers familiar with JavaScript and Node.js.

NestJS: A modern, structured approach

NestJS is known for building scalable and efficient Node.js server‑side applications. It uses progressive JavaScript and fully supports TypeScript, while also allowing pure JavaScript. It incorporates object‑oriented, functional, and reactive programming.

Key features: What sets it apart?

Modular architecture

import { Module } from '@nestjs/common';

@Module({
  imports: [
    CacheModule
  ],
  controllers: [PaymentController],
  providers: [PaymentService],
})
export class PaymentModule {}

Scalability – Modules enable flexible component replacement and microservice support.

Dependency injection

import {
  HttpException, Injectable, NotFoundException
} from '@nestjs/common';

@Injectable()
export class PaymentService {
  constructor() {}

  getReceipt() {
    return 'Payment Receipt';
  }
}

import { Controller, Get, Post, Body } from '@nestjs/common';
import { PaymentService } from './payment.service';
@Controller('payment')
export class PaymentController {
  constructor(private readonly paymentService: PaymentService) {}
  @Get()
  getPaymentReceipt() {
    return this.paymentService.getReceipt();
  }
}

Type safety – TypeScript catches potential errors during development.

Koa.js: Elegant and lightweight

Koa.js is a smaller, more expressive web framework created by the Express team. It lets you abandon callbacks and handle errors using async functions.

Key features: What makes it unique?

Context object (ctx) – Captures request and response details.

const Koa = require('koa');
const app = new Koa();

app.use(async (ctx) => {
  const { method, url, request, response } = ctx;
  console.log('Method :' + method + ' Request : ' + request);
});

app.listen(3000);

Middleware composition

const Koa = require('koa');
const app = new Koa();

app.use(async (ctx, next) => {
  await next(); 
});

Async/await support

const Koa = require('koa');
const app = new Koa();

app.use(async (ctx) => {
  const data = await fetchData();
  ctx.body = `Data: ${data} `;
});

app.listen(3000);

Error handling – Supports various error handling methods.

Hapi.js

Hapi.js (HTTP API) is an open‑source framework for building scalable web applications, especially REST APIs. Created by Walmart Labs to handle high‑traffic events like Black Friday.

Key features: Highlights

Configuration‑driven design – Routes, settings, and plugins are defined via configuration objects.

const Hapi = require('@hapi/hapi');

const server = Hapi.server({
  port: 3000,
  routes: {
    cors: true,
  },
});

server.route({
  method: 'GET',
  path: '/',
  handler: (request, h) => {
    return 'Hello, Hapi!';
  },
});

async function start() {
  await server.start();
  console.log(`Server running at ${server.info.uri} `);
}

start();

Powerful plugin system

const start = async function() {
  const server = Hapi.server();

  await server.register([{
    plugin: require('plugin1'),
    options: {}
  }, {
    plugin: require('plugin2'),
    options: {}
  }]);
};

Authentication and authorization

server.route({
  method: 'GET',
  path: '/private-data',
  handler: (request, h) => {
    // Access private data only if authenticated
    const user = request.auth.credentials;
    return `Welcome, ${user.username}! `;
  },
  options: {
    auth: 'jwt', // Use JWT authentication strategy
  },
});

Input validation – Built‑in validation for headers, params, query, payload, etc.

Adonis.js

Adonis.js is a full‑stack MVC framework for Node.js, offering scalability and maintainability. It follows a Laravel‑like structure and includes an ORM, authentication, and routing out of the box.

Key features: Highlights

Full‑stack MVC – Organizes code for easier maintenance and extension.

Integrated ORM (Lucid) – Provides an expressive query builder and supports multiple databases.

const Model = use('Model');

class User extends Model {
}

module.exports = User;

const Route = use('Route');
const User = use('App/Models/User');

Route.get('users', async () => {
  return await User.all()
})

Authentication system – Built‑in support for user authentication and authorization.

Conclusion

In 2024 these backend frameworks hold significant market positions. Whether you value Express.js’s simplicity, NestJS’s structure, Koa.js’s elegance, or Adonis.js’s productivity, choosing the right framework is crucial and depends on your project’s specific needs.
