This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.
The getRegistration()
method of the ServiceWorkerContainer
interface gets a ServiceWorkerRegistration
object whose scope URL matches the provided document URL. The method returns a Promise
that resolves to a ServiceWorkerRegistration
or undefined
.
Syntax
ServiceWorkerContainer.getRegistration(scope).then(function(ServiceWorkerRegistration) { ... });
Parameters
scope
Optional- A unique identifier for a service worker registration — the scope URL of the registration object you want to return. This is usually a relative URL.
Returns
A Promise
that resolves to a ServiceWorkerRegistration
object, or undefined
.
Example
navigator.serviceWorker.getRegistration('/app').then(function(registration) { document.querySelector('#status').textContent = 'ServiceWorkerRegistration found.'; });
