Application Testing
- Reactivate the server as in step 6, with the command “server node.js” on the CMD.
- Next open your browser and access the “http://localhost:3000/” URL.
- Reopen the “http://localhost:3000/” url on a new tab or another browser.

- You will see when one submits data, then all open windows will update automatically. And on the CMD console you can create notifications as you need.
