Examples

Logging the loadTime of the largest contentful paint

This example uses a {{domxref("PerformanceObserver")}} notifying of new largest-contentful-paint performance entries as they are recorded in the browser's performance timeline. The buffered option is used to access entries from before the observer creation.

const observer = new PerformanceObserver((list) => {
  const entries = list.getEntries();
  const lastEntry = entries[entries.length - 1]; // Use the latest LCP candidate
  console.log(lastEntry.loadTime);
});
observer.observe({ type: "largest-contentful-paint", buffered: true });
