Trying out our application

We should now be able to use our application. Load it up and browse to http://localhost:3000. Log in to the site, and we should be redirected to the chat page. We should see our room form component. We can add a room here or we can load it up in another tab or browser and create a room there, seeing it appear on the other window in real time.

We can then join one of the rooms in both windows and chat with ourselves. Each chat message should appear in real time.
