How can I implement authentication with Vue and Socket.IO?

You can implement authentication in Vue with Socket.IO by using JWT tokens. First, set up your backend to issue tokens upon successful login.

What steps do I need to follow for the backend setup?

You'll need to create an endpoint for login that verifies user credentials and generates a JWT token. Then, send this token to the client.

How do I store the JWT token on the client side?

You can store the JWT token in localStorage or a Vuex store. Just make sure to include it in the headers of your Socket.IO connection.

What about handling token expiration?

You should implement a refresh token mechanism or prompt the user to log in again when the token expires.
