PHP Asynchronous Push Notification management

PHP Webpush API implementation

Allows to send messages via WebPushAPI, on different providers (Google Chrome, Mozilla), asynchronously, on multiple recipients, using multiple API keys., _(*1)

[!IMPORTANT]
This repository is no longer maintained and may be removed in a near future. You may consider creating a fork if you still require it., _(*2)

Looks stable, but still experimental., _(*3)

Pusher is inspired and based on the awesome minishlink/web-push library, but with a different approach: * Guzzle 6 has been prefered for sending messages, thanks to its asynchronous and parallel requests management * A Push object is a bag that contains a Message, and Recipients associated to their handlers. * A Handler is responsible for the correct delivery of a Message to a Recipient - currently implemented: GCM handler, Mozilla handler. * Multiple Handlers can be used for a single Push, and a Handler may have several instances (i.e. when you use multiple GCM API keys) * Every Handler must be able to return a Promise for handling a Push, to make things asynchronous and allow bulk processing * The Pusher service is responsible to send a Push and change its state (_pending_ => done). * When the Push is done, it can tell which Recipients have not received the message and why (you may then unsubscribe them), _(*4)

Several types of Message are implemented: * A Ping message is a message without payload. Usually your service worker should fetch the payload at that moment (as it was in the earlier Webpush API implementations). * A Notification message contains a json with all the info to display a Webpush notification (title, body, icon, ...) * A ServerMessage contains a JSON which should be handled by your service worker to be sent to an active window instead of displaying a notification. This may help in changing remotely the DOM of an opened page., _(*5)

Some example JS files are provided., _(*6)
