การใช้ Test Data จาก CSV กับ Postman

const express = require('express');
const bodyParser = require('body-parser');
const app = express();
const PORT = 3000;

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

// Mock Data (เก็บใน Array)
let customers = [];

// Create - เพิ่มลูกค้าใหม่
app.post('/customers', (req, res) => {
    const customer = req.body;
    customers.push(customer);
    res.status(201).json({
        message: 'Customer created successfully',
        customer: customer,
    });
});

// Read - ดูข้อมูลลูกค้าทั้งหมด
app.get('/customers', (req, res) => {
    res.status(200).json(customers);
});

// Read - ดูข้อมูลลูกค้าตาม ID
app.get('/customers/:id', (req, res) => {
    const customerId = req.params.id;
    const customer = customers.find(c => c.customer_id === customerId);
    if (!customer) {
        return res.status(404).json({ message: 'Customer not found' });
    }
    res.status(200).json(customer);
});

// Update - แก้ไขข้อมูลลูกค้า
app.put('/customers/:id', (req, res) => {
    const customerId = req.params.id;
    const index = customers.findIndex(c => c.customer_id === customerId);
    if (index === -1) {
        return res.status(404).json({ message: 'Customer not found' });
    }
    customers[index] = { ...customers[index], ...req.body };
    res.status(200).json({
        message: 'Customer updated successfully',
        customer: customers[index],
    });
});

// Delete - ลบลูกค้า
app.delete('/customers/:id', (req, res) => {
    const customerId = req.params.id;
    const index = customers.findIndex(c => c.customer_id === customerId);
    if (index === -1) {
        return res.status(404).json({ message: 'Customer not found' });
    }
    const deletedCustomer = customers.splice(index, 1);
    res.status(200).json({
        message: 'Customer deleted successfully',
        customer: deletedCustomer,
    });
});

// Start Server
app.listen(PORT, () => {
    console.log(`Server running on http://localhost:${PORT}`);
});
