go-financial-chat-challenge

A simple multi chat-room, where participants can request stock values through the chat command /stock=appl.us where appl.usis the stock ticker.

The arquitecture consists on 4 docker containers running with the following services:

• The chat.
• A simple bot that listens to a queue, hits an API to get the stock value and return it through the other queue.
• RabbitMQ to support the two queues that provides communication between the services.
• PostgreSQL for user management.

Try it with Docker

Remove existing containers and images with:

• docker compose down -v --rmi all

Start:

• docker compose up

Create User:

• POST localhost:8080/users

{
    "username": "a username",
    "password": "a password"
}

Login:

• POST localhost:8080/login

{
    "username": "a username",
    "password": "a password"
}

Get the access token from the response and use it in the Authorization header like Bearer <accessToken>

Create a chat room:

• POST localhost:8080/rooms

{
    "title": "a title"
}

Get the roomId from the response and use it as a query param to join a room

Join a chat room (websocket):

• GET ws://localhost:8080/ws?roomId=307027e6-6768-4e2d-a9c2-3ff8bf5dcc0e

In the payload you send messages with:

{
    "msg": "Hello World!"
}

To trigger the bot to fetch a stock value, you send a message like:

{
    "msg": "/stock=appl.us"
}
