How do I set up JWT authentication with Vue Router?

To set up JWT authentication with Vue Router, you'll need to follow these steps: 1. Install necessary packages like axios and vue-router. 2. Create a login component to handle user authentication. 3. Use axios to send a POST request to your backend for login, and store the JWT in local storage. 4. Set up navigation guards in Vue Router to protect routes.

Can you explain how to create a login component?

Sure! In your login component, create a form with fields for username and password. Use v-model to bind these fields to data properties. On form submission, call a method that sends the credentials to your backend and handles the response.

What are navigation guards?

Navigation guards are functions that allow you to control access to certain routes in your application. You can use them to check if a user is authenticated before allowing access to specific routes.

How do I store the JWT after login?

You can store the JWT in local storage using localStorage.setItem('token', jwtToken); after receiving it from your backend. This way, you can retrieve it later for authenticated requests.
