How do I implement JWT authentication with Vue Router?

To implement JWT authentication with Vue Router, you need to set up a few key components. First, ensure you have a backend that issues JWTs upon successful login.

What steps do I need to take after getting the JWT from the backend?

After receiving the JWT, you should store it in local storage or a cookie. Then, configure your Vue Router to protect certain routes by checking for the token.

How can I protect routes in Vue Router?

You can use navigation guards in Vue Router. In your router configuration, add a beforeEach guard that checks if the token exists before allowing access to protected routes.

What if the token expires?

If the token expires, you should handle the error response from your API and redirect the user to the login page, prompting them to log in again.
