How do I implement token-based authentication in my application?

To implement token-based authentication, you typically use JSON Web Tokens (JWT). First, ensure your users can log in and receive a token.

What steps are involved in generating a JWT?

You need to create a payload with user information, sign it with a secret key, and then encode it to generate the token.

How do I validate the token on the server side?

On the server, you can decode the token using the same secret key and verify its signature to ensure it's valid.

What should I do if the token expires?

You can implement a refresh token mechanism that allows users to obtain a new token without logging in again.
