dicontainer

Tiny dependency container

• Handles resolution of dependencies
• Lazy instantiation (services arent created until they are needed)
• Understands Angular.js providers/services/factories/globals
• Provides simple React.js compatible Mixin for attaching services
• Tests for circular dependencies
• less than 1kb (gzipped)

Basic Usage

Setup

var Container = require('dicontainer');

var appContainer = new Container(logFunction /* optional */);

Registration

container.register(name, factory /* or service/provider */);

function MathService(other) {}
MathService.prototype.add = function (a,b) { return a+b; };
MathService.$inject = ['OtherService']; 

appContainer.register('MathService', MathService); // Dependencies are read from $inject property

// --- or ----

function MathService(other) {}
MathService.prototype.add = function (a,b) { return a+b; };

appContainer.register('MathService', MathService, ['OtherService']); // Dependencies are specified as array

// --- or ----

function MathService(other) {}
MathService.prototype.add = function (a,b) { return a+b; };

appContainer.register('MathService', ['OtherService', MathService]); // Dependencies and service are specified as array

Resolution

var instance = container.resolve(name);

var MathService = appContainer.resolve('MathService');
MathService.add(1,2);

Mixin

Service instances are attached to this.services

var Calculator = React.createClass({
    
    mixins: [appContainer.Mixin('MathService', 'OtherService')]

    render: function () {
        this.services.MathService.add()
    }
});
