This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The json()method of the PushMessageData interface extracts push message data by parsing it as a JSON string and returning the result.

Syntax

var myData = PushEvent.data.json();

Parameters

None.

Returns

The result of parsing push event data as JSON. This could be anything that can be represented by JSON — an object, an array, a string, a number...

Examples

self.addEventListener('push', function(event) {
  var myData = event.data.json();

  // do something with your data
});
