1️⃣ Initialize JWT Manager

import { JwtManager } from 'jwt-smith';

const jwtManager = new JwtManager({
	publicKey: process.env.PUBLIC_KEY || 'your-public-key',
	refreshTokenKey: process.env.REFRESH_TOKEN_KEY || 'your-refresh-key',
	signOptions: {
		algorithm: 'RS256',
		expiresIn: '1h',
	},
	verifyOptions: {
		algorithms: ['RS256'],
	},
	middlewareConfigs: {},
});

2️⃣ Sign a JWT Token

const token = await sign({
	payload: { id: 1, role: 'user' },
	secret: 'my-secret-key',
});

3️⃣ Verify a JWT Token

const decoded = await verify({
	token: 'eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9...',
	secret: 'my-public-key',
});
console.log(decoded); // { id: "123", role: "admin", iat: ..., exp: ... }

4️⃣ Middleware for JWT Header Authentication

import express from 'express';
import { validateJwtHeaderMiddleware } from 'jwt-smith';

const app = express();
app.use(validateJwtHeaderMiddleware);

app.get('/protected', (req, res) => {
	res.json({ message: 'Access granted!', user: req.user });
});

5️⃣ Middleware for JWT Cookie Authentication

import { validateJwtCookieMiddleware } from 'jwt-smith';

app.use(validateJwtCookieMiddleware);

app.get('/secure', (req, res) => {
	res.json({ message: 'Secure route accessed!', user: req.user });
});
