Features

• Hybrid REST and WebSocket Servers - Provides a full server-side implementation for managing persistent, bidirectional communication channels.
• Event-Driven Message Dispatching - Provides an event dispatcher to route incoming binary network frames to specific handler functions efficiently.
• Session Variable Stores - Uses in-memory key-value stores to attach custom data and track user identity across a session.
• Bidirectional Binary Streams - Facilitates the transmission of raw byte streams and encoded text between the server and remote clients.
• Buffered Network Streaming Libraries - Ships a library for managing buffered incoming and outgoing raw bytes and text over network connections.
• Broadcast Messaging - Implements a system for real-time event distribution by broadcasting messages to multiple connected sessions.
• Websocket Connection Managers - Manages persistent WebSocket connections including lifecycle event handling and session state tracking.
• WebSocket Servers - Provides a framework for implementing servers that manage bidirectional communication and persistent connections.
• Full-Duplex HTTP Communication - Enables simultaneous bidirectional data exchange by upgrading HTTP server connections to a full-duplex protocol.
• Handshake Upgrade Handlers - Includes a utility that validates handshake headers to convert HTTP requests into full-duplex communication channels.
• HTTP Upgrade Handlers - Converts standard HTTP requests into persistent connections and attaches them to a session manager.
• Incoming Message Processors - Executes specific functions to process incoming text or binary messages upon receipt.
• Protocol Upgrade Negotiators - Implements the handshake and protocol transition logic to convert stateless HTTP requests into persistent bidirectional streams.
• Session State Management - Maintains session state between clients and servers over persistent bidirectional connections.
• Text and Binary Message Exchanges - Allows sending and receiving data as either UTF-8 encoded text or raw binary bytes.
• Binary Buffer Transports - Implements low-level data transmission using raw memory buffers to optimize network throughput and minimize encoding overhead.
• Protocol Upgrades - Provides mechanisms for negotiating and upgrading standard HTTP connections to persistent WebSocket protocols.
• Real-Time Data Pushing - Implements capabilities for pushing real-time updates and broadcasting messages to WebSocket clients.
• Session Connect-Disconnect Emitters - Triggers specific logic and emits events when clients connect, disconnect, or send messages.
• Wire Representation Caches - Optimizes multi-client broadcasts by computing the binary payload once and sharing it across multiple connections.
• JSON Data Exchange - Supports encoding and decoding JSON for transporting state and data between clients and the server.
• Optimized Broadcast Engines - Features a broadcast engine that optimizes multi-client transmissions through wire-representation caching.
• Connection Configurations - Provides settings for managing network communication parameters, including message size limits and timeouts.
• Connection Control Frame Handlers - Provides custom handlers for protocol-level ping, pong, and close messages to maintain connection health.
• Data Compression - Applies per-message deflate compression to outgoing payloads to reduce network bandwidth usage.
• Request Source Filtering - Implements filtering logic based on the request origin to restrict access during the initial connection phase.
• Session-Targeted Writes - Allows sending text or binary messages to a specific connected user with a custom write deadline.
• Payload Transmissions - Supports per-message deflate compression to reduce bandwidth usage for outgoing payloads.
• WebSocket Origin Validators - Enforces same-origin policies during the WebSocket handshake to restrict which hosts can establish a connection.
• Request Size Limiters - Sets a maximum byte threshold for incoming messages to protect server resources from excessive data consumption.
• Wire-Representation Caches - Optimizes multi-client broadcasts by caching the binary wire representation to avoid redundant processing.
• Messaging Systems - Minimalist framework for WebSocket sessions.
• Web Frameworks - Lightweight WebSocket framework for real-time interactions.
• Communication and Real-time - A framework for building WebSocket services.
• Messaging - Listed in the “Messaging” section of the Awesome Go awesome list.
• Messaging Systems - Minimalist framework for WebSocket sessions.
