Go Microservices Realtime Finance Chat Application with RabbitMQ, Websockets, JWT, Mux, Gorm(MySQL), And React
The goal of this exercise is to create a browser-based chat application using Go. This application allows several users to talk in one or more chatrooms and also to get stock quotes from an API using a specific command.
The following tools are required to run the project
- Go (Golang)
- RabbitMQ
- MySQL
- Docker(optional)
I use the poly repo ideology, hence, the project works in collaboration with two other repositories:
-
go-stockbot : A decoupled service that calls an API using a "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) and recieves a csv file. The bot parses the received CSV file and then sends a message to the chatroom service using a message broker (RabbitMQ).

React client app : The frontend application that allows registered users to log in and talk with other users in a chatroom. It also allows users to post messages as commands into a chatroom with the following format
/stock=stock_code
Repo Link : https://github.com/ong-gtp/go-chat-react.git
This service reads published stock bot requests to env.STKBT_RECEIVER_QUEUE queue on RabbitMQ and reads the processed stock response on env.STKBT_PUBLISHER_QUEUE queue on RabbitMQ.
RabbitMQ is the message broker between the bot service and the chat service. To run it with docker, run the folling command in your terminal:
docker run -d --hostname rabbitmq-svc --name rbbtmq -p 15672:15672 -p 5672:5672 rabbitmq:3.11.3-management
copy the .env.example to .env and update the entries.
