Golang Base Server

Introduction

This repo is meant as a base starting point for a Go backend server. It includes an opinionated project structure and basic user-management-related implementations.

Requirements

• Go 1.20
• A MySQL server

Included implementations

• User CRUD operations (Some may be missing)
• Session management
• Email verification
• Simple license management

Dependency injection

wire is used for dependency injection. Check out the docs here: https://github.com/google/wire.

Providers are declared in each abstraction layer (ie. handler, service, etc.) in the files with name wire.go. Add to those files if you need to declare new providers.

To use wire to generate code:

wire path/to/init_server/module

Code structure/design

The structure of the repo roughly follows the MVC design pattern. To reduce unnecessary complexity, only two main abstraction layers are included (handler -> service).

Handler

Contains only http-related logic:

• Parsing of request
• Handling of HTTP response
• Authentication
• etc.

Service

Contains business logic. Data access layer is also placed here. DB accesses should be done in this layer.

Lib

lib should contain other functions/logic that do not belong in handler or service.

Local development

1. Check conf/config.yaml. Make sure that the configurations are correct for your local system. (Check if the DB DSN matches your local DB's username and password)

2. Execute go run cmd/main.go. The server will run on port 8080.
