typescuti v1.0.2

Typescuti

Typescuti is a small dependency injection container for Typescript/JavaScript.

Motivation

There are some other dependency injection libraries, but many of them are decorator's based. There isn't problem with that, however thinking on architecture, our domain layer shouldn't have external dependencies. Through Typescuti, we can inject all dependencies on infrastructure layer.

Installing

Using NPM:

npm install typescuti --save

Or using Yarn:

yarn add typescuti

Usage

// user.service.ts
import { type  User, UserService } from  './user.service'

export  class  UserController {

	// register classes those should be injected
	static  inject  = [UserService]
	
	constructor (private  readonly  service:  UserService) {}

	getUsers ():  User[] {
		return  this.service.getUsers()
	}
}

// user.controller.ts
import  express  from  'express'
import  *  as  container  from  'typescuti'
import { UserController } from  './user.controller'

const  app  =  express()

// resolve classes
const  userController  =  container.resolve<UserController>(UserController)

app.get('/user', (_, res) => {
	const  response  =  userController.getUsers()
	return  res.send(response)
})

app.listen(3333)
