core-di v0.7.1

core-di

Simple and minimal dependency injection (DI) for ES6

Installation

npm install core-di --save

Quickstart

Giving the following (note that the use of ES7 decorators here is not mandatory )...

car.js

import GearBox from './gear-box'
import SteeringWheel from './steering-wheel'
import {inject} from 'core-di'

@inject(
  GearBox,
  SteeringWheel
)
export default class Car {
  
  constructor (geerBox, steeringWheel) {
    this.geerBox = geerBox
    this.steeringWheel = steeringWheel
  }
}

You can then setup the di container as follows...

container.js

import Car from './car'
import GearBox from './gear-box'
import SteeringWheel from './steering-wheel'
import {Container} from 'core-di'

const container = new Container()

container.add(Car)
container.add(GeerBox)
container.add(SteeringWheel)
  
export default container

At which point you can then use the container to construct an item with all its dependencies resolved like so...

main.js

import Car from './car'
import container from './container'

const car = container.resolve(Car)

console.log(car instanceof Car) // -> true
console.log(car.geerBox instanceof GeerBox) // -> true
console.log(car.steeringWheel instanceof steeringWheel) // -> true
