const express = require('express');
const { csrfProtection } = require('node-auth-csrf');

const app = express();

app.use(csrfProtection(process.env.CSRF_SECRET));
app.get("/csrf-token", (req, res) => {
    const csrfToken = req.csrfProtection.generateToken();
    res.json({ csrfToken });
});

app.get('/protected', (req, res) => {
