Browser-based chat application

A simple browser-based chat application using Node.js

Requirements

• Allow registered users to log in and talk with other users in a chatroom.
• Allow users to post messages as commands into the chatroom with the following format /stock=stock_code
• Create a decoupled bot that will call an API using the stock_code as a parameter (https://stooq.com/q/l/?s=aapl.us&f=sd2t2ohlcv&h&e=csv, here aapl.us is the stock_code).
• The bot should parse the received CSV file and then it should send a message back into the chatroom using a message broker like RabbitMQ. The message will be a stock quote using the following format: “APPL.US quote is $93.42 per share”. The post owner will be the bot.
• Have the chat messages ordered by their timestamps and show only the last 50 messages.

Bonus (Optional)

• Have more than one chatroom. => DONE!
• Unit test the functionality you prefer. => DONE!
• Handle messages that are not understood or any exceptions raised within the bot. => DONE!

Installation

• You must have installed node in your system.
• Pull the repository in one folder of your choice.
• You will need to install RabbitMQ:3-management (To manage the queues between the bot and the chat app) and MongoDB (To handle the users and passwords). The first one I did it with docker toolbox with the following command: docker run -d --hostname jobsity-rabbit -p 5672:5672 -p 8081:15672 --name jobsity_rabbit rabbitmq:3-management. On the other hand, for the MongoDB, I installed and setted up a local version on my machine.
• Edit both environment files in the jobsity-chat folder and the jobsity-decoupled-bot folder to meet your environmental requirements. Every .env file explains itself its internal variables.
• Execute the command: npm install inside the jobsity-chat folder and the jobsity-decoupled-bot folder to install node_modules.
• Once you do the previous points, you can execute jobsity-chat app and jobsity-decoupled-bot apps both with the command: npm run dev in each folder (open different terminals).
• If you want to run the test, execute the command: npm run test in the jobsity-chat folder.
• Now you have both apps running on your machine. You could enter the Jobsity-chat application in port 8000 by default.
• The last thing you will need is users. You have to create a collection called user in your jobsity database on MongoDB and add as many documents as users you want. The structure of the document is the following:
• When you enter the application, it will ask you for a room, enter any name you want.
