ayapingping-go

ayapingping-go

ayapingping-go generates standard project structure to build applications in Golang that follow Clean Architecture and Domain-Driven Design concept.

Getting started

Installation

You can use the go install method:

go install github.com/dalikewara/ayapingping-go/v3@latest

or, you can also use the go get method (DEPRECATED since go1.17):

go get github.com/dalikewara/ayapingping-go/v3

Usage

To generate new project, just simply run ayapingping-go command:

ayapingping-go

then enter your project name & your go module path. After you confirm your inputs, the ayapingping-go generator will setup the project for you.

What's next?

Just start working on your project, make changes.

Project structure

To implement the concept of Clean Architecture and Domain-Driven Design, and to keep them understandable, we try to structure the project like this:

main.go

• In this file, you initialize dependencies, injections, and anything required to start and run your application
• You can use command go run main.go or make start to run your application

src/service

• In this package, you put your application handlers, servers or clients. Example:
  • src/service/rest/, to handle REST requests from client
  • src/service/grpc/, to handle gRPC requests from client
  • src/service/cron/, to handle CRON
  • etc...
• Also in this package, you put presenters or anything to be done between client and your application.

src/config

• In this package, you put any functions to set up constant variables, env variables, messages or anything about configurations
• For constant const configuration, you may use the variable directly from anywhere

src/adapter

• In this package, you put any functions to connect to external frameworks or connections like database, external client, etc

src/entity

• Entity is your main business model
• Here you define your main object models or properties for your business, like database model, DTO (Data Transfer Object), etc.
• Keep this package as simple as possible. Don't code anything that is not related to the model itself

src/library

• In this package, you create custom helper functions
• Provide reusable helpers for your application
• You may call any functions inside this package from anywhere

src/repository

• Repository is a place where you communicate with the real external data resource, like database, cloud service, external service, etc.
• It's always better to keep your repository as simple as possible, don't add too much logic here
• If you have to, you can separate the operations into smaller methods
• You should always call your repository methods inside the use case package
• You may use your src/library functions directly in this package
• Any changes outside this package should not affect your repositories (except changes for business entity)
• If you need config variables, database frameworks, or external clients, pass/inject them as a dependency
• You can use your own style as long as it doesn't break the main idea

src/usecase

• Use case is your main business logic
• You should always call your repository methods in this package
• You may use your src/library functions directly in this package
• Any changes outside this package should not affect your use cases (except changes for business entity and repository)
• If you need config variables, external clients, or repositories, pass/inject them as a dependency
• You can use your own style as long as it doesn't break the main idea

infra

• In this place, you put any infrastructure configurations or scripts to help you deploy your project in a server or vm
• It is always BETTER TO create folders based on what environment used, example:
  • infra/dev, for development
  • infra/staging, for staging
  • infra/prod, for production
  • etc...

Make your own

You're free to create your own style to suit your requirements as long as still follow the main architecture concept. You can create folders like; migration to place your database migrations, tmp to place temporary files, etc.
