$app/navigation

import {
	function afterNavigate(callback: (navigation: import("@sveltejs/kit").AfterNavigate) => void): void
A lifecycle function that runs the supplied callback when the current component mounts, and also whenever we navigate to a URL.
afterNavigate must be called during a component initialization. It remains active as long as the component is mounted.
afterNavigate,
	function beforeNavigate(callback: (navigation: import("@sveltejs/kit").BeforeNavigate) => void): void
A navigation interceptor that triggers before we navigate to a URL, whether by clicking a link, calling goto(...), or using the browser back/forward controls.
Calling cancel() will prevent the navigation from completing. If navigation.type === 'leave' — meaning the user is navigating away from the app (or closing the tab) — calling cancel will trigger the native browser unload confirmation dialog. In this case, the navigation may or may not be cancelled depending on the user’s response.
When a navigation isn’t to a SvelteKit-owned route (and therefore controlled by SvelteKit’s client-side router), navigation.to.route.id will be null.
If the navigation will (if not cancelled) cause the document to unload — in other words 'leave' navigations and 'link' navigations where navigation.to.route === null — navigation.willUnload is true.
beforeNavigate must be called during a component initialization. It remains active as long as the component is mounted.
beforeNavigate,
	function disableScrollHandling(): void
If called when the page is being updated following a navigation (in onMount or afterNavigate or an action, for example), this disables SvelteKit’s built-in scroll handling.
This is generally discouraged, since it breaks user expectations.
disableScrollHandling,
	
function goto(url: string | URL, opts?: {
    replaceState?: boolean | undefined;
    noScroll?: boolean | undefined;
    keepFocus?: boolean | undefined;
    invalidateAll?: boolean | undefined;
    invalidate?: (string | URL | ((url: URL) => boolean))[] | undefined;
    state?: App.PageState | undefined;
}): Promise<void>
Allows you to navigate programmatically to a given route, with options such as keeping the current element focused.
Returns a Promise that resolves when SvelteKit navigates (or fails to navigate, in which case the promise rejects) to the specified url.
For external URLs, use window.location = url instead of calling goto(url).
@paramurl Where to navigate to. Note that if you've set config.kit.paths.base and the URL is root-relative, you need to prepend the base path if you want to navigate within the app.
@paramopts Options related to the navigationgoto,
	function invalidate(resource: string | URL | ((url: URL) => boolean)): Promise<void>
Causes any load functions belonging to the currently active page to re-run if they depend on the url in question, via fetch or depends. Returns a Promise that resolves when the page is subsequently updated.
If the argument is given as a string or URL, it must resolve to the same URL that was passed to fetch or depends (including query parameters).
To create a custom identifier, use a string beginning with [a-z]+: (e.g. custom:state) — this is a valid URL.
The function argument can be used define a custom predicate. It receives the full URL and causes load to rerun if true is returned.
This can be useful if you want to invalidate based on a pattern instead of a exact match.
// Example: Match '/path' regardless of the query parameters
import { invalidate } from '$app/navigation';

invalidate((url) => url.pathname === '/path');
@paramresource The invalidated URLinvalidate,
	function invalidateAll(): Promise<void>
Causes all load functions belonging to the currently active page to re-run. Returns a Promise that resolves when the page is subsequently updated.
invalidateAll,
	function onNavigate(callback: (navigation: import("@sveltejs/kit").OnNavigate) => MaybePromise<void | (() => void)>): void
A lifecycle function that runs the supplied callback immediately before we navigate to a new URL except during full-page navigations.
If you return a Promise, SvelteKit will wait for it to resolve before completing the navigation. This allows you to — for example — use document.startViewTransition. Avoid promises that are slow to resolve, since navigation will appear stalled to the user.
If a function (or a Promise that resolves to a function) is returned from the callback, it will be called once the DOM has updated.
onNavigate must be called during a component initialization. It remains active as long as the component is mounted.
onNavigate,
	function preloadCode(pathname: string): Promise<void>
Programmatically imports the code for routes that haven’t yet been fetched.
Typically, you might call this to speed up subsequent navigation.
You can specify routes by any matching pathname such as /about (to match src/routes/about/+page.svelte) or /blog/* (to match src/routes/blog/[slug]/+page.svelte).
Unlike preloadData, this won’t call load functions.
Returns a Promise that resolves when the modules have been imported.
preloadCode,
	
function preloadData(href: string): Promise<{
    type: "loaded";
    status: number;
    data: Record<string, any>;
} | {
    type: "redirect";
    location: string;
}>
Programmatically preloads the given page, which means

ensuring that the code for the page is loaded, and
calling the page’s load function with the appropriate options.

This is the same behaviour that SvelteKit triggers when the user taps or mouses over an &#x3C;a> element with data-sveltekit-preload-data.
If the next navigation is to href, the values returned from load will be used, making navigation instantaneous.
Returns a Promise that resolves with the result of running the new route’s load functions once the preload is complete.
@paramhref Page to preloadpreloadData,
	function pushState(url: string | URL, state: App.PageState): void
Programmatically create a new history entry with the given page.state. To use the current URL, you can pass '' as the first argument. Used for shallow routing.
pushState,
	
function refreshAll({ includeLoadFunctions }?: {
    includeLoadFunctions?: boolean;
}): Promise<void>
Causes all currently active remote functions to refresh, and all load functions belonging to the currently active page to re-run (unless disabled via the option argument).
Returns a Promise that resolves when the page is subsequently updated.
refreshAll,
	function replaceState(url: string | URL, state: App.PageState): void
Programmatically replace the current history entry with the given page.state. To use the current URL, you can pass '' as the first argument. Used for shallow routing.
replaceState

// Exemple : Correspond à '/path' peu importe les paramètres de requête
import { function invalidate(resource: string | URL | ((url: URL) => boolean)): Promise<void>
Causes any load functions belonging to the currently active page to re-run if they depend on the url in question, via fetch or depends. Returns a Promise that resolves when the page is subsequently updated.
If the argument is given as a string or URL, it must resolve to the same URL that was passed to fetch or depends (including query parameters).
To create a custom identifier, use a string beginning with [a-z]+: (e.g. custom:state) — this is a valid URL.
The function argument can be used define a custom predicate. It receives the full URL and causes load to rerun if true is returned.
