Ws
This Go library provides low-level components for implementing high-performance WebSocket connections. It focuses on minimal memory allocations and efficient data throughput via a dedicated frame processor, an HTTP connection upgrader, and a compression layer.
The project distinguishes itself through the use of zero-allocation buffer reuse to reduce garbage collection pressure. It operates directly on raw network bytes for frame parsing and manages the lifecycle of connections through state-based tracking.
The library covers core network protocol capabilities including the transformation of standard HTTP requests into persistent sockets, the application of compression algorithms to data streams, and the low-level processing of network packets.
Features
- Zero-Allocation Buffers - Utilizes pre-allocated byte slices for reading and writing network frames to eliminate intermediate memory allocations.
- WebSocket Frame Processors - Provides a dedicated frame processor for reading and writing network frames using low-level buffers.
- Connection Upgraders - Provides a high-performance mechanism to transition standard HTTP requests into persistent WebSocket connections.
- Go WebSocket Libraries - Provides a high-performance, low-allocation WebSocket implementation specifically for the Go programming language.
- WebSocket Protocol Upgrades - Implements the mechanism for upgrading standard HTTP connections to the WebSocket protocol via a high-performance handshake.
- WebSocket Packet Processing - Provides low-level buffer access for reading and writing network frames to increase throughput and reduce allocations.
- Connection State Management - Tracks the lifecycle and protocol state of individual sockets to ensure correct frame processing order.
- WebSocket Implementations - Provides a low-level implementation of the WebSocket protocol, including handshakes and persistent bidirectional communication.
- Network Frame Parsing - Operates directly on raw network bytes to extract WebSocket headers and payloads without high-level abstractions.
- Data Compression - Provides a compression layer to reduce network bandwidth usage for transmitted WebSocket data streams.
- WebSocket Frame Compression - Implements a compression layer that reduces the size of individual WebSocket frames to save bandwidth.
- High-Concurrency Networking - Designed for high-concurrency networking using low-level buffer management to process large volumes of packets.
- Real-Time Data Streams - Enables the creation of low-latency systems that push frequent real-time updates to connected clients.
- Communication and Real-time - A low-level, high-performance WebSocket development package.
