Create a REST API with Node.js and Express from Cerewro

Express is the most popular web framework in the Node.js ecosystem. With Cerewro you can generate a complete REST API with authentication, validation, database and Swagger documentation in minutes.

Cerewro Chat — Generate complete REST API

Create a REST API with Node.js and Express to manage users and products: full CRUD routes, JWT authentication, Joi validation, SQLite connection and Swagger docs at /api-docs

Express server (index.js)

const express = require('express');
const cors    = require('cors');
const helmet  = require('helmet');

const app = express();
app.use(helmet()); app.use(cors()); app.use(express.json());

app.use('/api/users',    require('./routes/users'));
app.use('/api/products', require('./routes/products'));

app.listen(3000, () => console.log('API at http://localhost:3000'));

Run in production with PM2

npm install -g pm2
pm2 start src/index.js --name "my-api"
pm2 startup && pm2 save
pm2 logs my-api

Fastify as alternative: For small projects, consider Fastify instead of Express: up to 2x faster with native schema validation. Ask Cerewro: "Convert this Express API to Fastify".
