uNetworking/uWebSockets.js

Features

• WebSocket Servers - Implements a high-performance WebSocket server capable of handling massive numbers of concurrent real-time connections.
• Native Loop Integration - Hooks native network polling mechanisms directly into the Node.js event loop for efficient asynchronous I/O.
• Node.js Native Addons - Provides a native C++ addon that integrates high-performance protocol implementations directly into the Node.js runtime.
• Node.js Network Libraries - Provides a high-performance networking implementation specifically optimized for the Node.js runtime.
• High-Performance HTTP Servers - Optimized for extremely high HTTP throughput and low latency using native-layer efficiencies.
• Web Servers - Provides a lightweight server implementation for handling high-volume HTTP and WebSocket requests.
• Binary Protocols - Implements binary-first protocol handling for WebSocket frames to minimize string encoding overhead.
• Native Route Dispatching - Handles URL routing and request dispatching inside the C++ layer to reduce JavaScript overhead.
• Shared-Memory Architectures - Utilizes a common memory space for request and response objects to minimize allocation overhead.
• Real-Time Data Streaming - Enables real-time data streaming to many clients simultaneously with minimal resource overhead.
• Zero-Copy Buffers - Shares memory regions between C++ and JavaScript to avoid data duplication during message transmission.
