    const container = require('shark-di').BootstrapContainer;

    // weapon factory
    function sword(){
        return {name: 'sword', damage: 2.5};
    }

    // warrior constructor
    function ninja(weapon) {
        this.weapon = weapon;
        this.attack = function(){
            console.log('attack using ' + this.weapon.name + ': ' + this.weapon.damage + ' damage');
        } 
    }

    container.bind('weapon', sword); 
    container.bindClass('warrior', ninja);

    container.get(function(err, warrior){

        if(err)
        console.log(err);
        else
        warrior.attack();

    });

Promise based factories

Just return a promise/A+ in your factory.

 
    container.bind('weapon', function(){

        return promise_a_plus;

    });

Sample using RSVP Promise/A+ Library

    
    const RSVP = require('rsvp');
    
    container.bind('weapon', function(){

        return new RSVP.Promise(function(resolve, reject){
             resolve({name: 'shuriken',  damage: 1.0}); 
        });

    });
