ts-simple-ioc

A simple IoC container for TypeScript, strongly influenced by Microsoft.Extensions.DependencyInjection.

Features

• Simple service registration & resolution
• Type safe service resolution
• No package dependencies
• No requirement on services to know about the IoC framework, e.g. no decorators
• Singleton & transient lifetime support
• Constructor dependency injection
• Property dependency injection

Getting started

Installation

npm install --save ts-simple-ioc

Registering and resolving services

import { Container } from "ts-simple-ioc";

class ExampleService {
    constructor(public dependency: ExampleDependency) {}
}

class ExampleDependency {}

const container = new Container()
    .addTransient(ExampleService, (resolve) => new ExampleService(resolve(ExampleDependency)))
    .addSingleton(ExampleDependency, () => new ExampleDependency())
    .beginResolution();

const service = container.resolve(ExampleService);

Roadmap

• v1.1.0
  • Scoped lifetime support
• v1.2.0
  • Circular dependency detection
