Property

Type

Description

prefetch?

boolean | 'js'

(Optional) **Defaults to _true_.**

Whether Qwik should prefetch and cache the target page of this **Link**, this includes invoking any **routeLoader$**, **onGet**, etc.

This **improves UX performance** for client-side (**SPA**) navigations.

Prefetching occurs when a the Link enters the viewport in production (**on:qvisibile**), or with **mouseover/focus** during dev.

Prefetching will not occur if the user has the **data saver** setting enabled.

Setting this value to **"js"** will prefetch only javascript bundles required to render this page on the client, **false** will disable prefetching altogether.

usePreventNavigate$

Prevent navigation attempts. This hook registers a callback that will be called before SPA or browser navigation.

Return true to prevent navigation.

#### SPA Navigation

For Single-Page-App (SPA) navigation (via <Link />, const nav = useNavigate(), and browser backwards/forwards inside SPA history), the callback will be provided with the target, either a URL or a number. It will only be a number if nav(number) was called to navigate forwards or backwards in SPA history.

If you return a Promise, the navigation will be blocked until the promise resolves.

This can be used to show a nice dialog to the user, and wait for the user to confirm, or to record the url, prevent the navigation, and navigate there later via nav(url).

#### Browser Navigation

However, when the user navigates away by clicking on a regular <a />, reloading, or moving backwards/forwards outside SPA history, this callback will not be awaited. This is because the browser does not provide a way to asynchronously prevent these navigations.

In this case, returning returning true will tell the browser to show a confirmation dialog, which cannot be customized. You are also not able to show your own window.confirm() dialog during the callback, the browser won't allow it. If you return a Promise, it will be considered as true.

When the callback is called from the browser, no url will be provided. Use this to know whether you can show a dialog or just return true to prevent the navigation.
