Structure

Domain Driven Design (Hexagonal architecture)

├── application         // same as interface layer in hexagonal architecture
│   ├── cmd             // command line interface
│   ├── controller      // http controller
│   ├── middleware      // middleware that handles requests
│   └── route           // http route, which delegate impl to controller
├── domain   // domain layer in hexagonal architecture, never have any external dependencies
│   ├── entity  // entity in domain layer
│   ├── repository  // interface of persistence layer
│   └── service     // domain service layer
└── infrastructure  // handle external dependencies
    ├── configs     // every configs include gin framework
    └── persistence // impl of persistence layer

GOLDEN_RULE: domain/ 에는 외부 dependency가 들어오지 않는다.

• application/: application layer
  • 원래는 interface라고 명칭을 가져가야 하지만, 코드의 interface와 명칭이 중복되어, application 영역으로 명시함.
  • hexagonal에서 application service layer + interface layer의 코드가 들어있음
• domain/: domain layer
• infrastructure/: infra layer

Precommit-hook

refs

.zshrc or .bashrc

• go mod를 사용할 경우

... 중략 ...
export PATH="$PATH:$HOME/go/bin"
export GO111MODULE=on

$ go install golang.org/x/tools/cmd/goimports
$ go install golang.org/x/lint/golint

$ cp pre-commit.example .git/hooks/pre-commit
$ chmod +x .git/hooks/pre-commit

Cmd

local

• go run + local mysql db

$ make run
$ make build
$ make docker
$ make clean

$ ./bin/exchange-diray -phase=${phase}

sandbox

• local docker api server image + google cloud sql

$ make down && make up

prod

• google cloud run + google cloud sql (same as sandbox db)
• trigger (cloud build)
  • push to /main branch

Deploy env

• api server: google cloud run
• static server: google cloud storage FUSE
• db: google cloud sql
• ci / cd: Cloud Code & Cloud Build
• devops
  • Cloud Monitoring
  • Cloud Logging
  • Cloud Trace
