+In demo what should happen:
+If I open 2 browsers to /chat, both users should connect to chat room. Use redis to store state of chatroom.
+Have basic html ui showing the chat log using UL and single input box with send button to send messages.
+When I type a message in send message, call /send POST api to send message to backend. The chat room is updated with new message.
+All client browsers have an api called /poll that check if chat room on redis is updated. If updated, it will return 200 and frontend
+need to call GET /chat/all to pull all the messages in chat room which you will update the UL. Have a button called save where it will save the current chat room chat messages to database table chat with fields (id, create_at, chat_messages).
