Measure Render Performance

You can measure the render performance of your components with Polaris. Let's look at an example.

TypeScript
const instrument = measure('grid-sort');
function async onSort() {
  // measure render time
  try {
    instrument.start();
    await sort();
    requestAnimationFrame(() => instrument.done());
  } catch (error) {
    instrument.fail(error);
  }
}
