3 methods present?

[j2l]

Hello,
I'm studying the different routes used, and I see different methods, maybe I'm wrong, AFAIU:

• hello/pages.ts directly fetch the go API. Could also have been the pb API too, right?
• posts/page.svelte uses generated-types to watch<PostsResponse>
• [slug]/ and edit/ page.ts imports client from "$lib/pocketbase" to GET and POST items

I'd like to have a single page doing GET (list records, select one to read this record), POST (new record, edit in place) and DELETE.
What would be the best way to get this, while keeping auth and live (watch<PostsResponse> I guess) to edit records?

Thanks
