UDP

capacitor-udp is a maintained UDP plugin for CapacitorJS 3+ applications, enabling low-level network communication directly from hybrid mobile apps. It provides a comprehensive API for creating and managing UDP sockets, allowing developers to implement custom network protocols, real-time data streaming, or local network discovery features.

Key Features

• UDP Socket Management — Create, bind, update, and close UDP sockets with configurable properties like buffer size.
• IPv4 & IPv6 Support — Full compatibility with both IP address families for modern network environments.
• Multicast & Broadcast — Join/leave multicast groups, set TTL, and enable broadcast messaging for group communication.
• Data Transmission — Send and receive data buffers to specific addresses and ports with error handling listeners.
• Socket Control — Pause/resume socket activity, retrieve socket information, and list all active sockets.

Philosophy

The plugin focuses on providing a reliable, native-backed UDP implementation for Capacitor, filling a gap for developers who need direct network access beyond standard HTTP/WebSocket protocols in their cross-platform apps.
