Examples

navigation.addEventListener("navigate", (event) => {
  // Exit early if this navigation shouldn't be intercepted,
  // e.g. if the navigation is cross-origin, or a download request
  if (shouldNotIntercept(event)) {
    return;
  }

  // Returns a URL() object constructed from the
  // NavigationDestination.url value
  const url = new URL(event.destination.url);

  if (url.pathname.startsWith("/articles/")) {
    event.intercept({
      async handler() {
        // The URL has already changed, so show a placeholder while
        // fetching the new content, such as a spinner or loading page
        renderArticlePagePlaceholder();

        // Fetch the new content and display when ready
        const articleContent = await getArticleContent(url.pathname);
        renderArticlePage(articleContent);
      },
    });
