spin-delay

Smart Spinner Helper for React

There are a few annoyances when working with spinners. Network request can be so fast that rendering a spinner does more harm than good. Why render a spinner when loading the data only takes like 50ms?

This can be fixed by adding a delay. Only show the spinner when the request takes longer than 200ms for example. And what happens when the request takes 210ms? Right, we see a spinner for 10ms. This flicker can be annoying.

spin-delay solves these issues by wrapping your booleans, and only returning true after the delay, and for a minimum time of minDuration. This way you're sure that you don't show unnecessary or very short living spinners.

API

The examples below use the following data object:

function MyComponent() {
  const [{ loading }] = useFetch('http://example.com');

  // options are optional, and default to these values
  const showSpinner = useSpinDelay(loading, { delay: 500, minDuration: 200 });

  if (showSpinner) {
    return <Spinner />;
  }

  // ...
}
