Project purpose

Made this project to:
Evaluate the pros and cons of developing an Web API with Golang, in comparison with other stacks like NestJS(Typescrypt) and Laravel(PHP)
Get more familiar with golang
Having a template for golang Web Servers

Key features i want to analyse

conventional project file structure
request validation
authentication
available ORM's, query builders
Dockerfile for development and production
Livereload with docker
debugging
performance vs other frameworks / languages
unit tests
speed for developing slightly complex features
conventional programing paradigms and philosophy

Progress

OK - simple working api
OK - validation
OK - config file, env
OK - service layer pattern
OK - OpenAPI configuration
OK - some db integration    
OK - debug in container
OK - sqlc
