🔐 JWT Tokens with Cookies and Redis/in-Memory in One Line — The Magic of auth-verify

#node #webdev #cookie #javascript

Handling authentication in Node.js often means juggling JWTs, cookies, and Redis manually — configuring middleware, managing sessions, and writing repetitive code.

auth-verify simplifies all that.
It provides a clean and modern way to manage JWT authentication, secure cookies, OTPs, and more — all with minimal setup.

const Auth = require("auth-verify");
const auth = new Auth({ jwtSecret: "MySecret" storeTokens: "redis" }); // or you can use 'memory' for saving your tokens in-memory

// Sign a JWT and set it automatically as an httpOnly cookie
await auth.jwt.sign({ userId: 1 }, "1h", { res });

// Verify the token (reads cookie automatically)
await auth.jwt.verify({ req });

✅ What happens under the hood:

Token is generated and securely stored in Redis
A safe, httpOnly cookie is automatically set on the response
No need to manually use res.cookie() or middleware
Works seamlessly with Express, Fastify, or any custom server setup

🧰 Why Developers Love It

Simple JWT management — sign, verify, revoke in one line
Secure cookies — no cookie-parser needed
Built-in Redis / memory token store
Includes OTP system and sender support (e.g., Telegram, email, SMS)
Works anywhere — Express, custom HTTP servers, even bots

💡 Example: Minimal Login System

app.post("/login", async (req, res) => {
  const token = await auth.jwt.sign({ userId: 1 }, "1h", { res });
  res.json({ success: true, token });
});

app.get("/me", async (req, res) => {
  const user = await auth.jwt.verify({ req });
  res.json({ user });
});
