App Mentioned in Awesome Fiber

Golang application template. Based on clean architecture principles

  • internal/domain - business models and rules
  • internal/app - "App" applicaiton setup
  • internal/usecase - business logic implementations through usecase and repository interfaces
  • internal/controller - controllers implementations that orchestrate various usecases
  • migrations - application migrations
  • config - application configuration structs and helpers
  • pkg - additional, non-dependant infrastructure and logic that can be also used externaly, outside of current project scope
  • cmd - entrypoints to the applications
  • embed.go - files and directories that have to be embeded into the applications (migrations for ex.)
  • gen - autogenerated stubs
