 However, you can use any router library. A lot of people use [page.js](https://github.com/visionmedia/page.js). There's also [navaid](https://github.com/lukeed/navaid), which is very similar. And [universal-router](https://github.com/kriasoft/universal-router), which is isomorphic with child routes, but without built-in history support.
