How do I implement JWT authentication in a Node.js Express app?
To implement JWT authentication, you'll need to install the necessary packages like jsonwebtoken and express-jwt. Do you want a step-by-step guide?
Yes, please provide the steps.
First, set up your Express app. Then, create a login route that generates a JWT when the user logs in. Finally, protect your routes using middleware that verifies the token.
What should I include in the JWT payload?
Typically, you should include user ID and roles in the payload. This helps in identifying the user and managing permissions.
