How do I implement refresh tokens in an Express application?

To implement refresh tokens in an Express app, you need to set up a token generation mechanism and a secure storage method.

What libraries do I need to use for this?

You can use libraries like jsonwebtoken for token creation and express-session for session management.

How do I store the refresh tokens securely?

Store refresh tokens in an HttpOnly cookie or a secure database to prevent XSS attacks.

Can you show me a code example?

Sure! Here's a basic example:

const jwt = require('jsonwebtoken');
const express = require('express');
const app = express();

app.post('/login', (req, res) => {
    const user = { id: 1 }; // Example user
    const accessToken = jwt.sign(user, 'access_secret', { expiresIn: '15m' });
    const refreshToken = jwt.sign(user, 'refresh_secret');
    res.json({ accessToken, refreshToken });
});
