Market Share Chat

A chat app build with NodeJs, Typescript and React

Available features and flow:

• New users can sign up
• Registered users can log in and talk with other users in a chatroom and then log out
• Users can post messages as commands into the chatroom with the following format /stock=stock_code
• When a user post a valid command, a decoupled bot will call the Stooq API using the received stock_code to get a CSV with quote informations
• The Bot will parse the received CSV file and then post a message to a RabbitMQ queue with the quote info.
• Then RabbitMQ will send the message to the subscriber( chat server) and the chat server will build a message and send to the chatroom using the following format: “{stock} quote is ${close value} per share”. This message owner will be the bot.
• Chat messages are limited to the last 50 messages.

Possible future features:

• Multiple chat rooms and an option to choose a room or create a new room
• Store room and chat data on DB (encrypt messages)
• Show online users on screen

Known mistakes:

• Message Id is hardcoded
• Default room info is harcoded
• No unit tests
