To implement Background Sync, you need to register a service worker in your web app. The service worker script will handle network requests and store them when the user is offline. Once the user is back online, the service worker will send these stored requests. Here's a basic example:
if ('serviceWorker' in navigator) {
navigator.serviceWorker.register('/sw.js').then(function(reg) {
console.log('Service Worker Registered', reg);
// Request permission for notifications
Notification.requestPermission().then(function(status) {
console.log('Notification permission status:', status);
});
});
}
The service worker script (sw.js) will handle the background synchronization logic:
self.addEventListener('sync', function(event) {
if (event.tag === 'sync-emails') {
event.waitUntil(syncEmails());
}
});
function syncEmails() {
// Logic to send emails or notifications
return fetch('/send-emails').then(function(response) {
return response.json();
}).then(function(data) {
console.log('Emails sent:', data);
}).catch(function(err) {
console.log('Error syncing emails:', err);
});
}
By implementing Background Sync, you can ensure that your
email campaigns reach your audience at the best possible time, maximizing your marketing efforts.
