Here’s an example from the [Static Pages plugin](https://meta.discourse.org/t/static-pages-plugin-dl-static-pages/69698).

```javascript
/my-plugin/assets/javascripts/discourse/my-plugin-route-map.js.es6

export default function(){
  this.route('dl-static-pages', {path: '/page'}, function(){
    this.route('page', {path: '/' }, function(){
      this.route('show', {path: '/:slug/:id'});
    });
  });
};

```
