The abstract of the VAPID specification explains everything: An application server can voluntarily identify itself to a push service using the described technique. This identification information can be used by the push service to attribute requests that are made by the same application server to a single entity. This can used to reduce the secrecy … Read more
Solved: First thing is service worker only works in secure mode either in https or localhost. It doesnot work in local resources like file:// or http. and second issue was during registration. navigator.serviceWorkerContainer .register(‘service-worker.js’) .then(function(reg){
