⚛️⏳
React Async for Client

🎬 Demo · 🌟 GitHub · 📦 Package

👋 Introduction

This package helps you use async function without the need to migrate to ⚛️ React 19 and server-side rendering!

• ✨ Supports utility hooks to create and render async tasks.
• ✨ Supports AbortSignal and automatic abort on re-render.

🚀 Install

npm i react-client-async

✅ useAsync Hook

You can use the useAsync hook to create a task.

console.log(useAsync(fn, args, options));

✅ Async Component

You can use the Async component to render an async component.

<Async
  $fc={fc} // may be an async function component
  $waiting={waiting} // waiting component
  $fallback={fallback} // fallback component
  {...props} // props for the function component
/>

🎬 Demo of Recursive Async Component

Easy to wrap a recursive async component and memoize it.

const Rec: FC<{ n: number }> = wrap(
  async ({ [$signal]: signal, n }) =>
    // break the recursion
    (n <= 0) ? 0 : (
    // delay and recursion
      <>
        {await delay(99, signal)}
        {n} <Rec n={n - 1} /> {n}
      </>
    )
);

⏳ What is Next?

• ⏳ useAsyncIterable hook
• ⏳ AsyncIterable component

async function* IterableComponent() {
  yield* OtherIterableComponent();
  yield  await component1();
  yield  await component2();
  yield  <div>...</div>;
}
