NavigationTransition

Baseline 2026

Newly available

Since ⁨January 2026⁩, this feature works across the latest devices and browser versions. This feature might not work in older devices or browsers.

The NavigationTransition interface of the Navigation API represents an ongoing navigation, that is, a navigation that hasn't yet reached the navigatesuccess or navigateerror stage.

It is accessed via the Navigation.transition property.

Instance properties

finished Read only: Returns a Promise that fulfills at the same time the navigatesuccess event fires, or rejects at the same time the navigateerror event fires.
from Read only: Returns the NavigationHistoryEntry that the transition is coming from.
navigationType Read only: Returns the type of the ongoing navigation.

Examples

async function cleanupNavigation() {
  await navigation.transition.finished;
  // Navigation has completed successfully
  // Cleanup any ongoing monitoring
}
