deepin

Manage objects creation and dependencies using a descriptive way. It's a simple approach to inversion of control.

It currently only supports constructor injection by order, not by name

Install

$ yarn add deepin

Usage

/* importing UserController, UserService & UserRepository... */
import {Dependency, Injector} from 'deepin'
 
const injector = Injector.createAndResolve([
  new Dependency('UserController', {useClass: UserController}, ['UserService']),
  new Dependency('UserService', {useClass: UserService}, ['UserRepository']),
  new Dependency('UserRepository', {useClass: UserRepository})
])
 
/**
 * Create a brand new instance of the UserController
 * on each call
 */
const userController = injector.get('UserController')
 
/**
 * Always retrieve the SAME instance of a UserController
 */
const userController = injector.getUnique('UserController')

Shortcut usage for useClass :

/* importing UserController, UserService & UserRepository... */
import {give, Injector} from 'deepin'
 
const injector = Injector.createAndResolve([
  give(UserController, ['UserService']),
  give(UserService, ['UserRepository']),
  give(UserRepository)
])
