dein - dependency injection framework

A small dependency injection framework for node.js.

• Register modules with dependencies.
• Register literals without dependencies.
• Dependency injection framework is immutable.

Features

• dein is lazy. Only dependencies which are used are resolved
• dein allows async dependency resolution by using promises. You can mix synchronous factory methods with asynchronous ones.
• dein will automatically find the required dependency. No need to define the order of dependencies.

Quick Start

npm install dein

const dein = require('dein');

Examples

dein
  .registerLiteral('someString', 'Hello World')
  .register('someModule', someString => `${someString}!!!`)
  .resolve('someModule')
  .then((result) => {
    console.log('Result: ' + result);
    // Expected: `Result: Hello World!!!
  });

Tests
