SvelteKit Skill

Svelte 5 runes provide advanced reactivity in SvelteKit 2 using `$state` for variables, `$derived` for computed values, and `$effect` for side effects. This approach replaces traditional reactive declarations for more predictable state handling in components.

The best way to handle data fetching and form submission in SvelteKit is using server load functions and form actions. Server load functions fetch data securely, while form actions handle user input and data mutations on the server side.

File-based routing in SvelteKit 2 maps your file structure to URLs, automatically generating routes. You can create dynamic routes by adding brackets to filenames, allowing a single component to handle multiple path parameters efficiently.

Yes, SvelteKit 2 supports TypeScript for type-safe web development and allows the creation of API routes. You can define server-side endpoints within your project structure to handle external requests and return data.

Svelte 5 runes manage props using the `$props` rune for accepting component inputs and the `$bindable` rune to enable two-way binding. This ensures efficient and explicit data flow between parent and child components.

Yes, you can implement authentication and security headers in SvelteKit using server hooks. Server hooks intercept requests to validate user sessions and inject necessary HTTP security headers before routing completes.
