How to implement JWT in MERN stack?

To implement JWT (JSON Web Tokens) in a MERN stack (MongoDB, Express.js, React.js, Node.js) application, you need to follow a few steps. First, you need to set up a MongoDB database to store user information. Then, you can use the Express.js framework to create a server that handles authentication and authorization. You'll need to use a library like Passport.js to handle token verification and user authentication. When a user logs in, the server generates a JWT token and sends it to the client. This token needs to be stored securely on the client-side, such as in local storage or cookies. In subsequent requests, the client needs to include the JWT token in the Authorization header. On the server-side, you can use middleware to validate the token and protect your routes. Once the token is verified, you can access user information and allow or deny access to certain routes or resources based on the user's permissions.
