Build Status Coverage Status npm version

depenject is a lightweight and fast IoC container to resolve dependencies, achieving Inversion of Control (IoC) between their dependencies.


For the latest stable version:

npm install depenject


There are many ways to contribute to depenject:



In order to build the depenject, ensure that you have Git and Node.js installed.

Clone a copy of the repo:

git clone

Change to the depenject directory:

cd depenject

Install tools and dev dependencies:

npm install

Use one of the following to build and test:

npm run build       # Build the library into "dist" directory.
npm run test        # Test the library code.
npm run coverage    # Generates the coverage from the tests.

A simple sample to copy-and-paste

// name-provider.ts

import { resolver } from 'depenject';

export default class NameProvider {
  public name: string = "World";

  static [resolver]() {
    return new NameProvider();
// hello-service.ts

import { Container, resolver } from 'depenject';

import NameProvider from './name-provider';

export default class HelloService {
  private nameProvider: NameProvider;

  constructor(nameProvider: NameProvider) {
    this.nameProvider = nameProvider;

  static [resolver](container: Container) {
    return new HelloService(container.resolve(NameProvider));

  sayHello() {
    console.log("Hello " + + "!");
// hello.ts

import { Container, ContainerBuilder, resolver } from 'depenject';
import NameProvider from './name-provider';
import HelloService from './hello-service';

let container = new ContainerBuilder()

// resolve dependencies

let helloService = container.resolve(HelloService);
let nameProvider = container.resolve(NameProvider);

// execution

helloService.sayHello(); = "Rodrigo Speller"

The hello sample outputs the below text in console:

Hello World!
Hello Rodrigo Speller!
