JsDic

Dependecy injection container for javascript inspired by Angular.js

License: MIT

Features

• value, service and factory definition in Angular.js style
• like in Angular.js, dependencies can be defined by an array of names or parsed from function
• circular dependency detection
• works with browser, node.js and browserify

Installation

npm

npm install --save jsdic

browser

Load file jsdic.js and use JsDic class.

Example

function AjaxService(ajaxUrl) {
	this.ajaxUrl = ajaxUrl;
	// ...
}

function AjaxController(service, data) {
	this.service = service;
	this.data = data;
	// ...
}

var JsDic = require('jsdic'); // node, browserify
var dic = new JsDic();
dic
	.value('ajaxUrl', '/some-ajax-action')
	.value('initialData', [1, 2, 3])
	.service('ajaxService', AjaxService)
	.factory('ajaxController', function (ajaxService, initialData) {
		return new AjaxController(ajaxService, initialData);
	});

var ctrl = dic.get('ajaxController');
// or
var ctrl = dic.ajaxController;
// or
var ctrl = dic['ajaxController'];

// dependencies can be defined explicitly
dic
	.value('ajaxUrl', '/some-ajax-action')
	.value('initialData', [1, 2, 3])
	.service('ajaxService', ['ajaxUrl', AjaxService])
	.factory('ajaxController', ['ajaxService', 'initialData', function (as, id) {
		return new AjaxController(as, id);
	}]);
