ServiceWorkerGlobalScope: skipWaiting() method

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since April 2018.

Secure context: This feature is available only in secure contexts (HTTPS), in some or all supporting browsers.

Note: This feature is only available in Service Workers.

The skipWaiting() method of the ServiceWorkerGlobalScope interface forces the waiting service worker to become the active service worker.

Use this method with Clients.claim() to ensure that updates to the underlying service worker take effect immediately for both the current client and all other active clients.

Syntax

js
skipWaiting()

Parameters

None.

Return value

A Promise that resolves with undefined after trying to activate the newly installed service worker.

Examples

While self.skipWaiting() can be called at any point during the service worker's execution, it will only have an effect if there's a newly installed service worker that might otherwise remain in the waiting state. Therefore, it's common to call self.skipWaiting() from inside of an InstallEvent handler.

The following example causes a newly installed service worker to progress into the activating state, regardless of whether there is already an active service worker.

js
self.addEventListener("install", (event) => {
  // The promise that skipWaiting() returns can be safely ignored.
  self.skipWaiting();

  // Perform any other actions required for your
  // service worker to install, potentially inside
  // of event.waitUntil();
});
