A very simple way for sending, and nothing else, push notifications using FireBase Clouding Messaging.

About

Package for Pushing Notifications using Firebase Cloud Messaging Protocol.

Such as its name suggests, the package is intended for providing a simple way for pushing notifications, and nothing else.

Note: It has not any support for pushing messages or notifications based on topics

Main features about SPN are:

• Intended for only push notifications - Keeping things simple!
• Push notifications are sent using only HTTP Protocol (https://firebase.google.com/docs/cloud-messaging/server)
• It is able for returning the FCM's raw response or a parsed one.
• Parsed responses have information about delivered / undelivered notifications, devices tokens that should be deleted, and about those ones should be resend.
• Also It has support for Group Device Messaging. See:
  • https://firebase.google.com/docs/cloud-messaging/android/device-group
  • https://firebase.google.com/docs/cloud-messaging/ios/device-group

For all about errors and exception triggering, please take a look at:

• https://firebase.google.com/docs/cloud-messaging/http-server-ref#table9

Installation

Require the latest version of Spn into your project

Or you can add it directly into your project's composer.json file:

Laravel configuration

Register the Spn Service Provider into your app configuration file config/app.php:

Then publish the package config file:

And finally in your .env file, add your Server's keys and project ID using the Keys you got from FCM:

To get these keys, you must create a new application on the Firebase Cloud Messaging console.

Getting started

Once everything is installed and configured, you can start to using all the helpers exposed by SPN, to achieve all tasks related with

• Push notifications.
• Querying responses.
• Handling Exceptions.
• Device Group Management.

Push Notifications

SPN can only handle Notification Messages via Firebase Http Protocol. The XMPP protocol is not currently supported.

Single Device

Multiple devices

Devices Group

Handling responses

Once a notification message has been sent, SPN holds the FCM response, so you can querying it for useful information. Check it out the following examples:

Getting the FCM's raw response

it returns:

Response's stats

it returns:

If you like to get only an specific stats information, you can use one of the following methods:

Note: For notification messages sent to a Device Group, the shouldBeDeleted, and shouldBeResend always be null.

Handling errors and Exceptions.

SPN config file config/spn.php defines 2 keys for specifying how errors should be handled:

• on_error: tell if an exception will be triggered when any of errors described in Interpreting a downstream message response are found
• on_partial_deliveries: tell if an exception will be triggered when a notification cannot be delivered to all of its recipients.

SPN defines the following exceptions:

• ConnectionException: Any exception thrown by GuzzleClient class.
• InvalidServerKeyException: There was an error authenticating the sender account.
• BadRequestException: Only applies for JSON requests. Indicates that the request could not be parsed as JSON, or it contained invalid fields
• InvalidServerErrorException: Any fatal error.
• UndeliveredNotificationException: Triggered when a notification was not delivered to any of its recipients (it requires setting on_partial_deliveries = true in config/spn.php )
• NontificationKeyAlreadyException: The Device Group cannot be created because it already exists.
• NotificationKeyNotFound: The Device Group Notification Key is invalid.

Device Group Messaging

According FCM:

"With device group messaging, you can send a single message to multiple instances of an app running on devices belonging to a group. Typically, "group" refers a set of different devices that belong to a single user. All devices in a group share a common notification key, which is the token that FCM uses to fan out messages to all devices in the group."

SPN exposes helpers for Device Group Management tasks:

Creating a Device Group

it replies with a notification_key:

Adding members to a Device Group

it replies with a notification_key:

Removing members from a Device Group

it replies with a notification_key:
