-- `options` - An optional object with the following properties:
-	- `history`: `"push"` | `"replace"` | `"auto"`

-		- `"replace"`: the router will use `history.replaceState` to update the URL without adding a new entry into navigation.

 For backward and forward navigation through the browser history, you can combine `navigate()` with the built-in `history.back()`, `history.forward()` and `history.go()` functions of the browser. If `navigate()` is called during the server-side render of your component, it has no effect.

 ### Replace entries in the browser history
 
 Normally, each time you navigate, a new entry is written to the browser's history. This allows navigation between pages using the browser's `back` and `forward` buttons. 
 
 The `<ClientRouter />` router allows you to overwrite history entries by adding the `data-astro-history` attribute to any individual `<a>` tag.
