go-cleanarch was created to keep Clean Architecture rules, like a The Dependency Rule and interaction between modules in your Go projects. More about Clean Architecture you can read in Uncle's Bob article.

Some benefits of using Clean Architecture:

1. Independent of Frameworks. The architecture does not depend on the existence of some library of feature laden software. This allows you to use such frameworks as tools, rather than having to cram your system into their limited constraints.
2. Testable. The business rules can be tested without the UI, Database, Web Server, or any other external element.
3. Independent of UI. The UI can change easily, without changing the rest of the system. A Web UI could be replaced with a console UI, for example, without changing the business rules.
4. Independent of Database. You can swap out Oracle or SQL Server, for Mongo, BigTable, CouchDB, or something else. Your business rules are not bound to the database.
5. Independent of any external agency. In fact your business rules simply don’t know anything at all about the outside world.

Source: The Clean Architecture

go-cleanarch assumes this files structure:

[GOPATH]/[PACKAGE_NAME]/[LAYER_NAME]

or

[GOPATH]/[PACKAGE_NAME]/[MODULE_NAME]/[LAYER_NAME]

For example

• go/src/github.com/roblaszczak/awesome-app
  • auth
    • domain
    • application
    • interfaces
  • content
    • domain
      • submodule1
      • submodule2
      • etc.
    • application
    • interfaces
  • frontend
    • domain
    • application
    • interfaces

The default layer names are as followed. It is possible to set different names by command line parameters see -domain/-application/-interfaces/-infrastructure bellow.

var LayersAliases = map[string]Layer{
    // Domain
    "domain":   LayerDomain,
    "entities": LayerDomain,

    // Application
    "app":         LayerApplication,
    "application": LayerApplication,
    "usecases":    LayerApplication,
    "usecase":     LayerApplication,
    "use_cases":   LayerApplication,

    // Interfaces
    "interfaces": LayerInterfaces,
    "interface":  LayerInterfaces,
    "adapters":   LayerInterfaces,
    "adapter":    LayerInterfaces,

    // Infrastructure
    "infrastructure": LayerInfrastructure,
    "infra":          LayerInfrastructure,
}

For examples please go to examples directory, with contains examples of valid and invalid architectures.

For more informations about Clean Architecture please read Uncle's Bob article

go get -u gopkg.in/roblaszczak/go-cleanarch.v1

go-cleanarch was only tested on Linux and also should work on OS X. Probably it doesn't work well on Windows.

To run in current directory:

go-cleanarch

To run in provided directory

go-cleanarch go/src/github.com/roblaszczak/awesome-cms

Process will exit with code 1 if architecture is not valid, otherwise it will exit with 0.

If you need to ignore *_test.go files in go-cleanarch check you can pass -ignore-tests

go-cleanarch -ignore-tests

It is useful when you have memory implementation in infrastructure layer and you need to test application service which depends of it.

If for some reason you need to allow to make forbidden import, for example

github.com/roblaszczak/go-cleanarch/examples/ignore-package/app to github.com/roblaszczak/go-cleanarch/examples/ignore-package/domain.

you can use

go-cleanarch -ignore-package=github.com/roblaszczak/go-cleanarch/examples/ignore-package/app 

The layer names can be set to a specific value with the following parameters. Each parameter stands for on layer.

go-cleanarch -domain dom -application appli -interfaces int -infrastructure outer

This would only allow the domain name to be dom, application hast to be appli, interafces must be int and infrastructure must be outer.

make test

make qa
