Go dependency injection approach using gin

Installation

$ go get github.com/dtop/go.ginject

Usage

1. Register to gin

	
	gin  := gin.New()
	deps := ginject.New()

	gin.Use(ginglog.Logger(120))
	gin.Use(gin.Recovery())
	gin.Use(ginject.DependencyInjector(deps)) // apply 
	
	// store your services
	
	deps.Register("db", database.New())
	
	deps.RegisterLazy("redis", func() interface{} {
	    
	    return redis.New()
	})
	

2. Use for single objects

func YourEndpoint(c *gin.Context) {

    deps := ginject.Deps(c) // alternatively: c.Get("dep").(ginject.Injector)
    
    var db database.DB
    if err := deps.Get("db", &db); err != nil {
        panic(err)
    }
    
    // use db
}

3. Use for structs

type SomeModel struct {
    Db *database.DB `inject:"db"`
}

func YourEndpoint(c *gin.Context) {

    deps := ginject.Deps(c) // alternatively: c.Get("dep").(ginject.Injector)
    
    model := &SomeModel{}
    if err := deps.Apply(model); err != nil {
        panic(err)
    }
    
    model.Db.connect()
    defer model.Db.Close()
    // ...
}
