Node.js Runtime & Frameworks

Production-Quality Guide with Real Code Examples

Quick Start

// Express.js server with middleware
const express = require('express');
const app = express();

// Middleware
app.use(express.json());

// Routes
app.get('/api/users', (req, res) => {
  res.json({ users: [] });
});

app.post('/api/users', async (req, res, next) => {
  try {
    const { email, name } = req.body;
    if (!email) return res.status(400).json({ error: 'Email required' });

    const user = { id: 1, email, name };
    res.status(201).json(user);
  } catch (error) {
    next(error);
  }
});

// Error handling
app.use((err, req, res, next) => {
  console.error(err.stack);
  res.status(500).json({ error: 'Internal server error' });
});

// Start server
app.listen(3000, () => console.log('Server running on port 3000'));

// NestJS example (TypeScript)
import { Controller, Get, Post, Body } from '@nestjs/common';
import { UserService } from './user.service';

@Controller('users')
export class UserController {
  constructor(private userService: UserService) {}

  @Get()
  getUsers() {
    return this.userService.findAll();
  }

  @Post()
  createUser(@Body() userData) {
    return this.userService.create(userData);
  }
}
