# Router app
Source: https://signy.dev/examples/router-app/
Pages, links and a route parameter, with the router in hash mode.
The router runs in hash mode, so the app works from any static host and inside the frame below. Each page is a component, and the layout renders the current one in an `Outlet`.
## Preview
[Open the page on its own](https://signy.dev/examples/router-app/demo/index.html.md)
## Code
Save it as an `.html` file and open it in a browser. It loads Signy and Iris CSS from the CDN, so there is nothing to install or build.
