It’s very simple to display a native notification using JavaScript.
Sending notifications
Websites can send push messages using the Web Push protocol.
Web Push: wake up a phone from deep sleep with urgent notifications
Is it possible to instantly deliver a web push notification to notify a phone call or to deliver any other time-sensitive notification?
Schedule or delay a web notification (like a reminder)
How can you create a web notification now that is displayed some time later?
How to send push notifications from a closed web app
One of the major features of web apps (both on desktop and mobile browsers) is the ability to send push notifications that are delivered even when the website is closed.
Web Push TTL: definition and maximum value
When you send a web push notification, you need to set the TTL: what is it? What value should you use? This article describes the TTL and the best practices for setting its value.
Multilingual notifications with Pushpad
It’s easy to create segments based on the user preferred language. In this way you can send different notifications to users with different language preferences.
Pushpad: new features for faster delivery of web push notifications
Now you can use Pushpad for delivering time-sensitive messages. For example you can notify urgent alerts or incoming phone calls.
How to send a web notification at a specific time
You can use the Push API to send timely notifications from your website (the notifications are delivered even when the user is not on your website). If you use Pushpad, a service for web push notifications, it is very simple to set the time when the notification must be delivered.
Unique notifications in a period of time (prevent duplicated notifications)
Sometimes an event can be triggered very frequently. However you want to send a notification to the user only once in a period of time: for example you may want to notify the event with at most one notification every hour (or day, etc.).
How to throttle notifications to user (show only once per period)
Some kinds of applications may create a lot of push notifications in a small amount of time.
Sometimes you just want to notify every single message, but other times might be better to reduce the number of notifications or avoid to send the same notification too many times in a short period of time.
Icons are no longer imported and resized
On 28 September 2016 we have changed how the icon_url of the Pushpad API works.
Send notifications in batch with the Push API
APNs an GCM have always provided a way to send notifications in batch.
It would be useful to see this feature for the Push API, which unfortunately doesn’t have it yet, meaning that you have to make an HTTP request for each endpoint. If you want to send a web push notification to N users at a time with a single API request you can still use a service like Pushpad which makes the hard work for you.
