 * Files with a `.js` or `.mjs` extension are more generic route handlers. These files should export functions corresponding to the HTTP methods they support (example below).
-* Instead of route masking, we embed parameters in the filename. For example `post/%id%.html` maps to `/post/:id`, and the component will be rendered with the appropriate parameter.
-* Nested routes (read [this article](https://joshduff.com/2015-06-why-you-need-a-state-router.md)) can be handled by creating a file that matches the subroute — for example, `routes/app/settings/%submenu%.html` would match `/app/settings/profile` *and* `app/settings`, but in the latter case the `submenu` parameter would be `null`.
