Development

This project can be booted up either

• natively with Go installed locally (assuming dependencies like PostgresSQL, Redis, etc. also exist)
• or by Docker Compose (PostgreSQL, Redis, etc. are included out of the box)

Please refer to Makefile or docker-compose.yml for details.

By default, the server will run at http://localhost:3333, but everything is configurable via .env file.

Tools

Some common development tools are introduced for better local development experience.

• cosmtrek/air - Live reload for Go apps
• GoTestTools/gotestfmt - go test output for humans
• swaggo/swag - Automatically generate RESTful API documentation with Swagger 2.0 for Go.

go install github.com/cosmtrek/air@latest
go install github.com/gotesttools/gotestfmt/v2/cmd/gotestfmt@latest
go install github.com/swaggo/swag/cmd/swag@latest

Alternatively, use make install to install the required Go tooling locally.

Documentation
