Progress update:

🟠 So far I've been able to render the list of rooms on the client (sorta). The issue I've noticed is that it does not render immediately when the page first loads. But if I make a change to the code (like adding a comment) which causes the server to "restart due to changes" then it shows up... I'm not yet sure why this is.

🟢 I'm able to switch between rooms when the user clicks on the "join" button.

🔴 I can't seem to figure out how to send messages specifically to a room. I thought it would be as simple as:

io.to(inputMsg.room).emit('received-chat', inputMsg);

Which is what the docs suggest ... but that currently isn't working.
