How do I implement JWT in a MEAN stack application?

To implement JWT in a MEAN stack, you'll need to set up your backend with Node.js and Express, and use a library like jsonwebtoken.

What are the steps to set up the backend for JWT?

First, install the necessary packages: express, mongoose, and jsonwebtoken. Then, create a user model and set up routes for registration and login.

How do I generate a token after user login?

After validating the user's credentials, use jsonwebtoken to sign a token with the user's ID and send it back in the response.

How can I protect my routes using JWT?

You can create a middleware function that verifies the token on protected routes, ensuring that only authenticated users can access them.
