Usage

<ResizeDetector> is a provider component that implements a simple DOM wrapper element and provides callbacks for resize events and custom hooks with dimension values for a consuming application or child component.

Two callback props are provided (onResize + onBreak), as well a custom hook(useResizeDetector) that a child component can use.

It provides the up-to-date width and height of its root DOM element as well as a simple tshirt size value (small | medium | large) that is determined by two breakpoints, which can be customized or disabled.

Custom Hooks Example

import ResizeDetector, { useResizeDetector } from "@paprika/resize-detector";

function ResizeConsumer() {
  const { width, height } = useResizeDetector();
  return (
    <div>
      {width} x {height}
    </div>
  );
}

function ResizeApp() {
  return (
    <ResizeDetector>
      <ResizeConsumer />
    </ResizeDetector>;
  );
}

Render Prop Example

import ResizeDetector, { useResizeDetector, ResizeDetectorContextValue } from "@paprika/resize-detector";

function ResizeApp() {
  return (
    <ResizeDetector>
      {({ width, height }: ResizeDetectorContextValue) => <div>{width} x {height}</div>}
    </ResizeDetector>;
  );
}

Callback Example

function ResizeApp() {
  const handleBreak = (size) => {
    doSomethingWithSize(size);
  }

  return (
    <ResizeDetector onBreak={handleBreak}>
      <ResizeConsumer />
    </ResizeDetector>;
  );
}
