How to get the current url in the browser in Angular 2 using TypeScript?

This is late but I thought it was worth updating. As of Angular2 final release you can import DOCUMENT from @angular/common and use that to get to the location.

import { Component, Inject } from '@angular/core';
import { DOCUMENT } from '@angular/common';

...

export class YourComponent {

    constructor(@Inject(DOCUMENT) private document: Document) { 
        console.log(this.document.location.href);
    }
}
