Node Apn
node-apn es una librería de Node.js y driver de notificaciones push utilizado para enviar notificaciones remotas a dispositivos Apple a través del servicio Apple Push Notification. Funciona como un cliente HTTP/2 que gestiona la construcción y transmisión de payloads JSON hacia la pasarela de notificaciones de Apple.
La librería soporta múltiples métodos de verificación de identidad, incluyendo autenticación basada en certificados mediante archivos PEM o PFX y autenticación basada en tokens con renovación automática. Incluye capacidades para enrutar tráfico a través de servidores proxy intermediarios y túneles HTTP seguros para evitar reglas de seguridad de red restrictivas.
El proyecto proporciona herramientas para la definición de payloads de notificación y la gestión de entrega, permitiendo el control de parámetros de alerta como prioridad, marcas de tiempo de expiración e identificadores de colapso. Maneja el encolado de mensajes asíncronos, multiplexación de streams sobre conexiones persistentes y seguimiento de entrega confiable para tokens de dispositivo.
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.
