As a backend developer, I was finding it difficult to use svelte kit to develop a SPA. Specifically it is hard to know from the docs how to handle authentication. The router is not much exposed. I hoped that 2.0 would add something in this area. nextjs docs have a section on server and client based authentication which is useful.
