Is the api endpoint public? In C, why limit || and && to evaluate to booleans? But after seeing that the Sveltekit docs recommended against disabling ssr (which would essentially make the app an SPA), I decided to listen. Server-side rendering and Single Page Application development; Code splitting Like +page.js, +page.server.js can export page options prerender, ssr and csr. For example, annotating export let data with PageData (or LayoutData, for a +layout.svelte file) tells TypeScript that the type of data is whatever was returned from load: In turn, annotating the load function with PageLoad, PageServerLoad, LayoutLoad or LayoutServerLoad (for +page.js, +page.server.js, +layout.js and +layout.server.js respectively) ensures that params and the return value are correctly typed.
