Async, Streaming with Promises & Infinite Loop #16403
Description
Describe the bug
The console gets spammed by Tick updated at: messages. More than it should.
Note that I don't see this issue if I rename +page.server.ts to +page.ts.
Unclear to me if I'm doing something I shouldn't or if this is a real issue. Please be gentle.
Reproduction
+page.server.ts
export const load = async ({fetch}) => { const res = await fetch('https://pokeapi.co/api/v2/pokemon/pikachu'); return {data: res.json()} }+page.svelte
<script lang="ts"> import type {PageProps} from "./$types"; import {readable} from "svelte/store"; import {invalidateAll} from "$app/navigation"; const {data}: PageProps = $props(); const tick = readable(Date.now(), (set) => { const id = setInterval(() => set(Date.now()), 1000); return () => clearInterval(id); }); $effect(() => { if ($tick) { console.log("Tick updated at:", $tick); invalidateAll(); } }); </script> <main> <svelte:boundary> <p>{JSON.stringify((await data.data), null, 2)}</p> {#snippet pending()} <p>loading...</p> {/snippet} </svelte:boundary> </main>Logs
