Build a Realtime app
Introduction
Note: This can be a pair programming activity or done independently.
We've now seen an alternative to HTTP that we can use to exchange data between a client and a server with websockets. For this lab, you're going to build a chat app using websockets with Express. Follow the requirements below and use the starter code to get started - you'll also be using jQuery and AJAX within your application to make this work.
Exercise
Requirements
- Setup the Express app to listen to sockets
- A socket message from the client should contain a name and the text for the message
- Your app should have a
/messageendpoint that creates a new message and sends that message to all of your sockets subscribers- If a message is empty, respond with a 400 response and an appropriate message to the console
- If a message has been accepted, respond with a 200 response and display the message to the page
- The page should keep a running history of your chat
Bonus:
- Add a participants lists that would pull from the names associated with the messages
Starter code
The starter code already include all the files and packages you need. The template index.ejs is already styled but feel free to change it.
