How to write SvelteKit middleware or interceptor for fetch both on server and client?

Question

As title says, how to you write middleware in SvelteKit? I know to do it in hooks.server.ts.

I succeed to intercept server requests, but it would be ideal to make interceptor or middleware for both client and server calls in SvelteKit.

Answer 1

You could potentially handle the fetch event in a service worker (kit docs).
