@random-di/container v0.3.0

In software engineering, dependency injection is a technique in which an object receives other objects that it depends on. These other objects are called dependencies. Source Wikipedia

@random-di/container helps you register your applications dependencies by providing a dependency injection container.

Installation

npm i --save @random-di/container

yarn add @random-di/container

Usage

import {createContainerBuilder, LifeCycle} from '@random-di/container'

// Declare some services
class ServiceA {
}

class ServiceB {
    constructor(serviceA: ServiceA) {}
}

// Construct the container using a container builder
const builder = createContainerBuilder()
    .addFactory('serviceA', () => new ServiceA(), LifeCycle.Singleton)
    .addFactory(
        'serviceB', 
        provider => new ServiceB(provider.get<ServiceA>('serviceB')), 
        LifeCycle.Transient
    )

// Build the container
const container = builder.build()

// Retrieve the services
const serviceA = container.get<ServiceA>('serviceA')
const serviceB = container.get<ServiceB>('serviceB')
