react-sync-hooks

Useful hooks you can use in asynchronous processes.

Live Demo CodeSandbox

usePromiseState

You can get the callback after the update is complete without using useEffect on state updates. In this way, it simplifies management in consecutively State updates.

Basic Usage

import { usePromiseState } from "react-sync-hooks";

export default function App() {
  const [promiseState, setPromiseState] = usePromiseState(0);

  return (
    <div className="App">
      <button
        onClick={() => {
          setPromiseState(
            1,
            // Triggered when state is updated.
            (s: any) => {
              console.log("State Updated:  " + s);
            }
          );
        }}
      >
        Set Promise State: {promiseState}
      </button>
    </div>
  );
}

useQueueState

It provides a synchronous update of state updates that occur asynchronously by queuing them.

Basic Usage

import { useQueueState } from "react-sync-hooks";

export default function App() {
  const [queueState, setQueueState] = useQueueState(0);

  return (
    <div className="App">
      <button
        onClick={() => {
          // Queues concurrent updates
          setQueueState((s: any) => s + 1);
          setQueueState((s: any) => s + 1);
          setQueueState((s: any) => s + 1);
        }}
      >
        Set Queue State: {queueState}
      </button>
    </div>
  );
}
