PushMessageData
Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.
The PushMessageData
interface of the Push API provides methods which let you retrieve the push data sent by a server in various formats.
Unlike the similar methods in the Fetch API, which only allow the method to be invoked once, these methods can be called multiple times.
Messages received through the Push API are sent encrypted by push services and then automatically decrypted by browsers before they are made accessible through the methods of the PushMessageData
interface.
Properties
