Wire is a tool for automating the wiring of components at runtime using dependency injection. The dependencies between components can be defined by the tag marked on the field of the struct, or by the parameters of the Init method.

easy start

repository struct looks like

package repo

import "github.com/peace0phmind/bud/factory"

func init() {
	factory.Singleton[MyRepo]() // registry MyRepo as a singleton service
}

// MyRepo to control model with db
type MyRepo struct {
	//...
}

func (mr *MyRepo) SaveData() {
	//...
}

service struct looks like


package service

import "github.com/peace0phmind/bud/factory"
import "repo"

func init() {
	factory.Singleton[MyService]() // registry MyRepo as a singleton service
}

type MyService struct {
	myRepo *repo.MyRepo `wire:"auto"`
}

func (ms *MyService) DoSomething() {
	// ...
	ms.myRepo.SaveDate()
	// ...
}

main.go

package main

import "github.com/peace0phmind/bud/factory"
import "service"

func main() {
	serv := factory.Get[servcie.MyService]()

	serv.DoSomething()
}
