PushManager: registrations() method
Deprecated: This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. Avoid using it, and update existing code if possible; see the compatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.
Non-standard: This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.
Note: This feature is available in Web Workers.
The registrations
method is used to ask the system about
existing push endpoint registrations.
Note:
This method has been superseded by the PushManager.getSubscription()
method.
Syntax
registrations()
Parameters
None.
Return value
A DOMRequest
object to handle the success or failure of the method call.
If the method call is successful, the request's result
will be an array of
PushRegistration objects.
PushRegistration
Those objects are anonymous JavaScript objects with the following properties:
pushEndpoint
-
A string representing the URL of the endpoint.
version
-
The current version that the push endpoint is at.
Examples
const req = navigator.push.registrations();
req.onsuccess = (e) => {
if (req.result.length > 0) {
req.result.forEach((result) => {
console.log(
`Existing registration ${result.pushEndpoint} ${result.version}`,
);
});
// Reuse existing endpoints.
} else {
// Register for a new endpoint.
const register = navigator.push.register();
register.onsuccess = (e) => {
console.log(`Registered new endpoint: ${register.result}`);
};
}
};
