Go-Kit generator.

This generator is still a work in progress

Go-kit generator is a cli application that generates boilerplate code for your go-kit services.

Why?

Because I'm lazy, and because it would make it easier for go-kit newcomers to start using it.

Installation

go install github.com/kujtimiihoxha/gk

Running the generator

gk must be run from a project inside the specified $GOPATH for it to work. When it is run for the first time it will search for gk.json configuration file, if it does not find it it will create one with the default settings.

Create a new service

Inside the project run:

gk new service hello

or the shorter command:

gk n s hello

this will create a new service called HelloService inside :

project
└───hello
│   └───pkg
│   │   └───service
│   │   │    service.go

service.go

package service

type HelloService interface {
	// Write your interface methods
}

Now you need to add the interface methods and initiate your service: e.x:

package service
import "context"
type HelloService interface {
	// Write your interface methods
	World(ctx context.Context, s string) (rs string, err error)
}

than run :

gk init hello

this will create the service struct , methods, endpoints, transport . The final folder structure is the same as addsvc

I don't like the folder structure!

The folder structure that the generator is using is following go-kit/kit#70 but that can be changed using gk.json all the paths are configurable there.

Cli Help

Every command has the -h or --help flag this will give you more info on what the command does and how to use it. e.x

gk init -h

will return

Initiates a service

Usage:
  gk init [flags]

Flags:
  -t, --transport string   Specify the transport you want to initiate for the service

Global Flags:
  -d, --debug           If you want to se the debug logs.
      --folder string   If you want to specify the base folder of the project.
  -f, --force           Force overide existing files without asking.
      --testing         If testing the generator.

What is working

The example you see here go-kit/kit#70

TODO-s

• Implement support for other transports besides http
• Implement the update commands, this commands would be used to update an existing service e.x add a new request parameter to an endpoint.
• Implement middleware generator (service,endpoint).
• Implement automatic creation of the service main file.
• Tests tests tests ...

Warnings

• I only tested this on the mac, should work on other os-s but I have not tested it, I would appreciate feedback on this.
• Commands may change in the future, this project is still a work in progress.

Contribute

Thanks a lot for contributing.

To test your new features/bug-fixes you need a way to run gk inside your project this can be done using test_dir.

Execute this in your command line :

export GK_FOLDER="test_dir" 

Create a folder in the gk repository called test_dir, now every time you run go run main.go [anything] gk will treat test_dir as the project root.
