Chat App in Go

Learning Go by building a Chat Application.

Things I learnt

• Testing and writing code following the TDD approach
• Rendering HTML templates.
• Implementing OAuth2 Login (Google, Github and Facebook).
• Communication via Websockets.
• Implementing a trace package that monitors all websockets activities(e.g. when a new user joins a chat, when a message is sent e.t.c)
• Modularising my codebase.

Running the program locally on your computer

• Make sure you Go installed on your system.
• Clone this repository in a directory of choice on your computer: git clone https://github.com/Falence/chat-app-golang.git
• Get personal access keys from the OAuth providers used (google, facebook, github). You can google how to do this.
  This permits us consume their API to have access to users information such as name, profile picture etc.
  
• In the chat directory, create a .env file and place these keys in it. See the image below.
  
• Install the 3rd party packages by going into the chat directory and running go mod tidy on your terminal. Same for the trace directory.
• cd into the chat directory and run go build -o chat to build the program.
• To run our program, type ./chat.
• You can now open the Chat App on different browsers: http://localhost:8080/chat
• You'll be prompted to login.
• Then you can now chat.
