🌊 stream v0.1.0 - Production-Ready SSE and WebSocket for Go 1.25+

✨ Highlights

• ✅ RFC 6455 compliant WebSocket - Full protocol implementation with 99 tests (84.3% coverage)
• ✅ RFC text/event-stream compliant SSE - Complete implementation with 215 tests (92.3% coverage)
• ✅ Zero external dependencies - Pure stdlib implementation
• ✅ Production-ready - 314 tests, load tested, stress tested
• ✅ High performance - 13K WebSocket broadcasts/s, near-zero allocation
• ✅ Type-safe - Generic Hub[T] for broadcasting

📦 Installation

go get github.com/coregx/stream@v0.1.0

🚀 WebSocket Features

Core Implementation:

• RFC 6455 compliant WebSocket protocol
• websocket.Conn - Connection with Read/Write API
• websocket.Upgrade() - HTTP to WebSocket handshake
• Frame parsing, fragment reassembly, UTF-8 validation
• Automatic Ping/Pong handling
• Close handshake with 15 standard codes

Broadcasting:

• websocket.Hub - Multi-client broadcast manager
• Thread-safe concurrent operations
• Broadcast(), BroadcastText(), BroadcastJSON()
• Automatic cleanup on failures

Performance:

• 11 μs/op for 10 clients
• 75 μs/op for 100 clients (~13K broadcasts/s)
• 223 MB/s throughput for large messages

🌊 SSE Features

Core Implementation:

• sse.Event - Event builder with fluent API
• sse.Conn - Connection management
• sse.Hub[T] - Generic type-safe broadcasting
• Automatic heartbeat support

Performance:

• 8 μs/op for 10 clients
• 52 μs/op for 100 clients

📊 Testing & Quality

• 314 total tests (215 SSE + 99 WebSocket)
• 84.3% coverage (SSE: 92.3%, WebSocket: 84.3%)
• 23 benchmarks with comprehensive metrics
• Load tested: 100 concurrent connections, 1,000 broadcasts
• Stress tested: 10MB messages, rapid connect/disconnect

📚 Documentation

• WebSocket Guide - 600+ lines
• SSE Guide
• README with Quick Start
• Comprehensive godoc for all public APIs

🎯 Examples

• WebSocket: Echo server, Chat server with Hub, Ping/Pong keep-alive
• SSE: Basic time stream, Multi-client chat
