# injector

TypeScript Dependency Injection using `reflect-metadata` and **typescript** 1.7+ with es7 experimental features enabled

### How it works

The purpose of this module is to allow you to do something like that:

```ts

// MyClass.ts

import { Inject } from 'ts-injector';

export class MyClass {

  @Inject('Foo')

  private foo: Foo;

  doFoo(): void {

    this.foo.foo();

  }

}

// Foo.ts

declare interface Foo {

  foo(): void;

}

```

And then create the instance of **MyClass** and inject the instance of **Foo** at runtime:

```ts

// test.ts

import { Injector } from 'ts-injector';

import { MyClass } from './MyClass';

import { Foo } from './Foo';

// create the real Foo class

class FooImpl implements Foo {

  foo(): void {

    console.log('foo bar');

  }

}

// instantiate the injector

var injector = new Injector();

// register an instance of FooImpl to be bind with people asking for @Inject("Foo")

injector.register('Foo', new FooImpl());

// create an instance of MyClass

var c = new MyClass();

// inject the needed dependencies

injector.inject(c);

// now you can call

c.doFoo();

// prints "foo bar"

```
