PerformanceNavigationTiming: domComplete property

A DOMHighResTimeStamp representing the time immediately before the user agent sets the document's readyState to "complete".

The domComplete property can be used to log the time when the DOM is complete.

Example using a PerformanceObserver, which notifies of new navigation performance entries as they are recorded in the browser's performance timeline. Use the buffered option to access entries from before the observer creation.

const observer = new PerformanceObserver((list) => {
  list.getEntries().forEach((entry) => {
    console.log(`${entry.name}: domComplete time: ${entry.domComplete}ms`);
  });
});

observer.observe({ type: "navigation", buffered: true });

Example using Performance.getEntriesByType(), which only shows navigation performance entries present in the browser's performance timeline at the time you call this method:

const entries = performance.getEntriesByType("navigation");
entries.forEach((entry) => {
  console.log(`${entry.name}: domComplete time: ${entry.domComplete}ms`);
});
