How can I implement JWT security in my Angular application?

To implement JWT security in your Angular app, you need to follow these steps: 1. Set up a backend to issue JWTs. 2. Install the necessary libraries like @auth0/angular-jwt. 3. Configure HTTP interceptors to attach the JWT to outgoing requests. 4. Handle token expiration and refresh.

What libraries do I need to install for JWT?

You should install @auth0/angular-jwt for handling JWTs in Angular. You can do this using npm: npm install @auth0/angular-jwt.

How do I configure the HTTP interceptor?

You can create an HTTP interceptor by implementing the HttpInterceptor interface. In the intercept method, you can add the JWT to the request headers before sending it.

What should I do if the token expires?

You should implement a refresh token mechanism. When the token expires, you can use the refresh token to obtain a new JWT without requiring the user to log in again.
