createResource in SolidJS
From the SolidJS cheat sheet · Resources & Data Fetching · verified Jul 2026
createResource
Fetch async data reactively with automatic loading/error tracking and optional source signals.
tsx
// Quick Reference
import { createResource } from "solid-js";
const [data] = createResource(fetchData);
// data(), data.loading, data.error💡 Pass a source signal as the first arg to auto-refetch when it changes
⚡ mutate() updates the local data optimistically without refetching
📌 refetch() manually triggers a new fetch — great for refresh buttons or polling
🟢 Combine with Suspense and ErrorBoundary for declarative loading states
