KUnifiedPush

UnifiedPush client library and distributor daemon.

Client Library

Getting Started

How to register for push notifications:

• Register on D-Bus with a service name
• Make your application D-Bus activatable
• Create an instance of KUnifiedPush::Connector.
• Communicate the endpoint URL provided by this to the corresponding server-side application.
• Connect to its messageReceived signal.

There's also support for the following security capabilities, in case your application server supports any of those:

• Message Encryption for Web Push (RFC 8291).
• Voluntary Application Server Identification (VAPID) (RFC 8292).

Supported Distributors

For the basic functionality any standard compliant D-Bus distributor should work. The graphical status and configuration user interface however only works with the kunifiedpush-distributor, as that needs a lot more access to distributor internal details than the standard interfaces provide.

D-Bus Distributor

UnifiedPush only specifies the protocol between distributor and client as well as between the server-side application and the push provider, but not the one between the push provider and the distributor. Supporting different push providers therefore requires provider specific code and configuration.

Configuration

There is a configuration KCM, alternatively this can be configured via the ~/.config/KDE/kunifiedpush-distributor.conf configuration file.

Push Notification KCM

In combination with our own distributor this allows configuring the push provider to use in System Settings, check the distributor status, and see all apps currently using push notifications.
