Features

• Apple Push Notification Integrations - Provides a comprehensive Node.js library for sending remote push notifications to Apple devices via APNs.
• iOS Push Notification Deliveries - Provides a dedicated driver for sending remote push notifications specifically to iOS devices via the Apple Push Notification service.
• API Payload Serializers - Transforms structured notification data into the specific JSON format required by the Apple push service API.
• Notification Payload Definitions - Provides structured setters and raw JSON support for defining the data, headers, and delivery parameters of device alerts.
• Device-Specific Deliveries - Manages the delivery of structured JSON payloads to specific device tokens while tracking delivery status.
• HTTP/2 Support - Implements a persistent HTTP/2 client specifically for reliable message delivery to Apple's push provider.
• Stream Multiplexing Management - Utilizes HTTP/2 stream multiplexing to send multiple notification payloads over a single persistent TCP socket.
• Notification Payload Generators - Includes tools for generating the specific JSON structures, badges, and alerts required by the Apple Push Notification service.
• Persistent HTTP Connections - Manages long-lived HTTP/2 connections to ensure efficient and reliable delivery of multiple notifications.
• Connection Certificate Verifiers - Verifies sender identity using PEM or PFX certificates during the initial TLS handshake with APNs.
• APNs Authentication Wrappers - Offers a unified module for managing secure connections via PEM certificates, PFX files, or tokens.
• Certificate-Based Authentication - Provides identity verification using PEM or PFX certificates to establish secure connections.
• APNs Connection Managers - Implements the secure connection logic required to communicate with Apple's notification gateway.
• Token-Based Authentication - Secures connections using automatically renewing tokens to maintain constant connectivity to notification services.
• Notification Delivery Queues - Handles asynchronous queueing and automatic retries to ensure notification messages reach their destination.
• Node.js Push Notification Integrations - Provides the necessary integration to trigger mobile push notifications from a Node.js server.
• Messaging Reliability - Implements asynchronous message queueing and delivery tracking to ensure notifications reliably reach Apple device tokens.
• Notification Parameter Controls - Allows fine-grained control over how devices display alerts through priority and expiration parameters.
• Traffic Routing Proxies - Directs notification traffic through intermediary servers to bypass restrictive corporate firewalls.
• Network Tunnels - Routes outgoing traffic through encrypted remote servers via HTTP tunnels to bypass network restrictions.
• Proxy Server Routing - Allows notification traffic to be routed through proxy servers to bypass corporate network restrictions.
