The video explains how to create an app-like feel for websites using SvelteKit and the experimental View Transitions API. By creating custom animations for page transitions and targeting specific elements like header and footer, developers can achieve subtle and smooth page animations. The tutorial also highlights the importance of progressive enhancement and performance optimization, and provides tips for designing user-friendly animations.
Sure, here are the key facts extracted from the provided text:
1. Web developers have been chasing the "app-like feel" for decades, especially since the rise of mobile apps.
2. Previously, web developers would emulate the stack navigation used in mobile apps to achieve this feel.
3. SvelteKit version 1.24 introduced the `onNavigate` lifecycle method.
4. The `onNavigate` method takes a callback, and if that callback returns a promise, SvelteKit will wait for it to resolve before completing the navigation.
5. The `startViewTransition` method is crucial for view transitions in SvelteKit and relies on two promises: one for taking a screenshot before navigation and another after the next page is ready.
6. Default animated transitions in SvelteKit include a crossfade effect between old and new pages.
7. Custom animations can be applied to achieve a stack navigation-like feel.
8. TypeScript may require additional handling for the `startViewTransition` method.
9. Specific elements like headers and footers can have their own animations during transitions.
10. Animations can be prevented from replaying when clicking on the same route by checking the `from` and `to` route IDs.
