• Features: Supports middleware, routing, and template engines. It's minimalistic, making it easy to learn and use.
• Use Cases: Suitable for web and mobile app development, including social media platforms.
• Companies Using It: Netflix, IBM, Accenture, Uber, Walmart15.
2. NestJS
• Overview: NestJS is a progressive Node.js framework built on TypeScript. It offers a modular architecture, dependency injection, and strong typing, making it perfect for complex applications.
• Features: Supports real-time communication and is scalable. It's ideal for building enterprise-level applications.
• Use Cases: Great for APIs, microservices, and real-time applications, including social media platforms.
• Companies Using It: Not explicitly listed, but popular among enterprise developers56.
3. Sails.js
• Overview: Sails.js is a full-stack framework that supports real-time applications. It's built on top of Express and includes features like data modeling and routing.
• Features: Offers built-in support for databases like MySQL and MongoDB. It's suitable for real-time applications.
• Use Cases: Ideal for building scalable, real-time web applications, including social media platforms.
• Companies Using It: Not explicitly listed, but popular for real-time applications56.
4. Adonis.js
• Overview: Adonis.js is a full-featured MVC framework that supports TypeScript. It's designed for building scalable and maintainable applications.
• Features: Includes ORM, real-time communication support, and a strong focus on security.
• Use Cases: Suitable for complex web applications, including social media platforms.
• Companies Using It: Not explicitly listed, but popular among developers for its robust features36.

Real-Time Communication

For real-time features like live updates or online status, consider using libraries like Socket.IO or Pusher alongside your chosen framework. These libraries enable real-time communication between the server and client.

Example with Express.js and Socket.IO

Here's a simple example using Express.js and Socket.IO to display real-time online status:

javascript

const express = require('express'); const app = express(); const server = require('http').createServer(app); const io = require('socket.io')(server); let onlineUsers = {}; io.on('connection', (socket) => {  console.log('User connected');  // Handle user login and update online status  socket.on('login', (userId) => {    onlineUsers[userId] = socket.id;    io.emit('updateOnlineStatus', onlineUsers);  });  // Handle user logout and update online status  socket.on('logout', (userId) => {    delete onlineUsers[userId];    io.emit('updateOnlineStatus', onlineUsers);  });  socket.on('disconnect', () => {    for (const userId in onlineUsers) {      if (onlineUsers[userId] === socket.id) {        delete onlineUsers[userId];        io.emit('updateOnlineStatus', onlineUsers);      }    }  }); }); server.listen(3000, () => {  console.log('Server listening on port 3000'); });

Conclusion

Choosing the best framework depends on your specific needs:

• Express.js for lightweight and flexible applications.
• NestJS for complex, enterprise-level applications with strong typing.
• Sails.js or Adonis.js for full-stack, real-time applications.

Each framework has its strengths, and integrating real-time communication libraries can enhance your social media platform's functionality.
