Periodic synchronization

code:js

navigator.serviceWorker.ready.then(function(registration) {

registration.periodicSync.register({

tag: 'get-latest-news', // default: ''

minPeriod: 12 * 60 * 60 * 1000, // default: 0

powerState: 'avoid-draining', // default: 'auto'

networkState: 'avoid-cellular' // default: 'online'

}).then(function(periodicSyncReg) {

// success

}, function() {

// failure

})

});

まだ periodicSync 存在しない？ 2019/4/4
