Function svelteKitLoadEdges

src/resolution/callback-synthesizer.ts:2045–2080

* SvelteKit file-convention data flow. A route directory's `+page.svelte` (a * `component` node) receives its `data` from the sibling `+page.server.{ts,js}` * / `+page.{ts,js}` `load` function and posts forms to its `actions` — wired by * the framework BY FILE PATH, with no static import between

(ctx: ResolutionContext, onYield: MaybeYield)

 * its loader.
