از ایده تا API آماده، در ۵ دقیقه

// 1. Setup Express + PostgreSQL
const express = require('express');
const { Pool } = require('pg');
const app = express();
const pool = new Pool({ ... });

// 2. Define schema migration
CREATE TABLE products (
  id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
  name VARCHAR(255) NOT NULL,
  price DECIMAL(12,2) NOT NULL,
  in_stock BOOLEAN DEFAULT true,
  created_at TIMESTAMPTZ DEFAULT now()
);

// 3. Write CRUD routes
app.get('/v1/products', async (req, res) => {
  const { rows } = await pool.query(
    'SELECT * FROM products ORDER BY created_at DESC'
  );
  res.json({ data: rows, total: rows.length });
});

app.post('/v1/products', async (req, res) => {
  const { name, price, in_stock } = req.body;
  // validation...
  const { rows } = await pool.query(
    'INSERT INTO products (name,price,in_stock) VALUES($1,$2,$3) RETURNING *',
    [name, price, in_stock]
  );
  res.status(201).json(rows[0]);
});

// 4. Add Swagger docs
/**
 * @swagger
 * /v1/products:
 *   get:
 *     summary: List all products
 *     ...
 */

// 5. Setup auth middleware
// 6. Write Postman collection
// 7. Configure CORS, rate-limit, error handling
// 8. Write migration scripts
// ... and 200+ more lines
