Introduction

With useTask, you can combine task with react <Suspense>

What is Task ?

type Task = <A>() => Promise<A>;

Task<A> represents an asynchronous computation that yields a value of type A and never fails.

What is <Suspense> ?

<Suspense> lets you display a fallback until its children have finished loading.

Getting Started

useTask

Create a task

const getTitle = () => new Promise<string>((rs) => rs("Hello"));
const Title = () => {
  return <h1>title</h1>;
};

Add useTask hook in the component

import { useTask } from "@richard-wang-tw/use-task";
const Title = () => {
  // the first argument is task
  // the second is unique id of the task
  const title = useTask(getTitle, "getTitle");
  return <h1>{title}</h1>;
};

Wrap the component with <suspense>

const TitleLoader = () => (
  <Suspense fallback={<h1>Loading</h1>}>
    <Title />
  </Suspense>
);

deleteTaskCache

You can use deleteTaskCache("getTitle") on timeout or triggered by user interaction.

This feature allow you to reload data on next render.
