Gone

What Is Gone?

Gone is a lightweight golang dependency injection framework; a series of Goners components are built in for rapid development of micro services.

Features

• Define the Goner interface to abstract dependencies.
• Dependency Injection:
  • Inject Goners.
  • Inject function arguments.
• Modular, detachable design.
• Startup process control.
• Testing support.
• Built-in components:
  • goner/config, supports dependency injection of configuration parameters.
  • goner/tracer, adds TraceId to call chains, supports link tracing.
  • goner/logrus, goner/zap, supports log recording.
  • goner/gin, integrates with the gin framework to provide HTTP request parameter dependency injection.
  • goner/viper, used to parse various configuration files.
  • ...

Quick Start

1. Install gonectr and mockgen

   go install github.com/gone-io/gonectr@latest
   go install go.uber.org/mock/mockgen@latest
   

2. Create a new project

   gonectr create myproject
   

3. Run the project

   cd myproject
   gonectr run ./cmd/server
   

   Or use run Make command if you have installed make:

   cd myproject
   make run
   

   Or with docker compose:

   cd myproject
   docker compose build
   docker compose up
   

Dependency Injection and Startup

Here's an example:

package main

import (
	"fmt"
	"github.com/gone-io/gone"
)

type Worker struct {
	gone.Flag // Anonymously embedding gone.Flag structure makes it a Goner, it can be injected as a dependency into other Goners or receive injections from other Goners.
	Name      string
}

func (w *Worker) Work() {
	fmt.Printf("I am %s, and I am working\n", w.Name)
}

type Manager struct {
	gone.Flag                         // Anonymously embedding gone.Flag structure makes it a Goner, it can be injected as a dependency into other Goners or receive injections from other Goners.
	*Worker   `gone:"manager-worker"` // Named injection GonerId="manager-worker" for Worker instance.
	workers   []*Worker               `gone:"*"` // Inject all Workers into an array.
}

func (m *Manager) Manage() {
	fmt.Printf("I am %s, and I am managing\n", m.Name)
	for _, worker := range m.workers {
		worker.Work()
	}
}

func main() {
	managerRole := &Manager{}

	managerWorker := &Worker{Name: "Scott"}
	ordinaryWorker1 := &Worker{Name: "Alice"}
	ordinaryWorker2 := &Worker{Name: "Bob"}

	gone.
		Prepare(func(cemetery gone.Cemetery) error {
			cemetery.
				Bury(managerRole).
				Bury(managerWorker, gone.GonerId("manager-worker")).
				Bury(ordinaryWorker1).
				Bury(ordinary, ordinaryWorker2)
			return nil
		}).
		// Run method supports dependency injection of parameters in its function.
		Run(func(manager *Manager) {
			manager.Manage()
		})
}

Summary:

1. In the Gone framework, dependencies are abstracted as Goners, which can be injected into each other.
2. By anonymously embedding the gone.Flag, the structure implements the Goner interface.
3. Before starting, load all Goners into the framework using the Bury function.
4. Use the Run method to start, where the function supports dependency injection of parameters.

Let's use Gone to write a web service below!

🌐Web Service

package main

import (
	"fmt"
	"github.com/gone-io/gone"
	"github.com/gone-io/gone/goner"
)

// Implement a Goner. What is a Goner? => https://goner.fun/guide/core-concept.html#goner-%E9%80%9D%E8%80%85
type controller struct {
	gone.Flag // Goner tag, when anonymously embedded, a structure implements Goner
	gone.RouteGroup `gone:"gone-gin-router"` // Inject root routes
}

// Implement the Mount method to mount routes; the framework will automatically execute this method
func (ctr *controller) Mount() gone.GinMountError {

	// Define request structure
	type Req struct {
		Msg string `json:"msg"`
	}

	// Register the handler for `POST /hello`
	ctr.POST("/hello", func(in struct {
		to  string `gone:"http,query"` // Inject http request Query parameter To
		req *Req   `gone:"http,body"`  // Inject http request Body
	}) any {
		return fmt.Sprintf("to %s msg is: %s", in.to, in.req.Msg)
	})

	return nil
}

func main() {
	// Start the service
	gone.Serve(func(cemetery gone.Cemetery) error {
		// Call the framework's built-in component, load the gin framework
		_ = goner.GinPriest(cemetery)

		// Bury a controller-type Goner in the cemetery
		// What does bury mean? => https://goner.fun/guide/core-concept.html#burying
		// What is a cemetery? => https://goner.fun/guide/core-concept.html#cemetery
		cemetery.Bury(&controller{})
		return nil
	})
}

Run the above code: go run main.go, the program will listen on port 8080. Test it using curl:

curl -X POST 'http://localhost:8080/hello' \
    -H 'Content-Type: application/json' \
	--data-raw '{"msg": "你好呀？"}'

The result is as follows:

{"code":0,"data":"to  msg is: 你好呀？"}

Quick Start

💡Concepts

The code we write is ultimately lifeless unless it is run. In Gone, components are abstracted as Goners, whose properties can inject other Goners. Before Gone starts, all Goners need to be buried in the cemetery; after Gone starts, all Goners will be resurrected to establish a Heaven, "everyone in Heaven is no longer incomplete, and what they want will be satisfied."
