A simple chat application using GoLang (for the first-time) + React

Simple Chat Application with Golang + React

First time using Go! Including the following that helped setup the backend structure

• Gin
• Melody

Setup

• Install Golang: https://golang.org/doc/install
• Make sure you have mysql installed and proper permissions and (npm or yarn)
• Log into mysql console and create a DB in mysql: create database sharedchat
• Load db from sql structure sql, replace following command with your username and password: mysql -u username -p sharedchat < sharedchat_db_structure.sql
• export SHAREDCHAT_DB_URL=username:password@/sharedchat?charset=utf8
• go install
• yarn or npm install
• npm install -g webpack
• webpack
• go-react-chat-app
• Go to localhost:5000 and use the chat!

Resources I learned a lot from

• A Tour of Go
• Gorilla Websocket Example
• Redis, Go, & How to Build a Chat Application - Compose
• Using WebSockets on Heroku with Go
• Writing Real-Time Web Apps in Go: Chat

Improvements for following iterations

• separate timestamp and username from stored message
• extract reusable parts of golang server into separate funcs and files
• use redigo to register websockets and allow chat to scale above one server
• add testing for golang server
• add testing for react app
• make it prettier
