Infector

Dependency injection for Node.js and the browser. Inspired by the dependency injection approaches in AngularJS and node-di. No relation to Infector++.

Usage

Grab `Infector`

In the browser, Underscore is a dependency and Infector is exposed as a global. So do something like:

<script src="underscore.js"></script>
<script src="infector.js"></script>

Using Bower:

$ bower install infector --save

In Node.js:

$ npm install infector --save

Specify dependencies

Use a constructor property:

function Foo(bar) {}
Foo.infect = ['bar'];
// or Foo.inject = ['bar'];

Register modules

There are two return options.

type: an instance of type will be returned via new:

function Foo() {}
infector.register({ foo: { type: Foo } });

If you want the module to be returned as a singleton:

infector.register({ foo: { type: Foo, isSingleton: true } });

value: the registered value will be returned:

infector.register({ foo: { value: 'Foo' } });

Get modules

Just do:

infector.get('foo');
