Part 2 / Page options / csr

Client-side rendering is what makes the page interactive — such as incrementing the counter when you click the button in this app — and enables SvelteKit to update the page upon navigation without a full-page reload.

As with ssr, you can disable client-side rendering altogether:

export const csr = false;

This means that no JavaScript is served to the client, but it also means that your components are no longer interactive. It can be a useful way to check whether or not your application is usable for people who — for whatever reason — cannot use JavaScript.
