I created an automatic breadcrumb trail for anyone that is interested in wiring up the primeNg breadcrumb

breadcrumb.component.ts

import {Component, Input} from 'angular2/core';
import {FORM_DIRECTIVES, NgClass} from 'angular2/common';
import {ROUTER_DIRECTIVES, RouteConfig, Router, RouteDefinition} from 'angular2/router';

/**
 * This component shows a router's paths as breadcrumb trails and allows you to navigate to any of them.
 * It subscribes to the router in order to update the breadcrumb trail as you navigate to a component.
 * By providing a RouteConfig the component will be able to use the 'as' name to display in the breadcrumbs links.
 */
