nostr-websocket

What problem does it solve?

Implementing robust and performant WebSocket connections for Nostr relays requires deep knowledge of RFC 6455, concurrency patterns, and language-specific optimizations. This skill provides expert guidance, battle-tested patterns, and production code examples to build reliable Nostr relay infrastructure.

Core Features & Use Cases

• RFC 6455 Protocol Mastery: Understand and implement the core WebSocket protocol, including handshake, framing, masking, and ping/pong.
• Concurrency & Performance: Apply advanced patterns for concurrent writes, subscription management, event batching, and zero-copy optimizations in Go, C++, and Rust.
• Security & Reliability: Implement critical security measures like origin validation, rate limiting, message size limits, and NIP-42 authentication.
• Use Case: "I'm building a Nostr relay in Go. Guide me on implementing a robust WebSocket connection with proper ping/pong handling and concurrent write protection."

Quick Start

Explain the core WebSocket protocol handshake and frame structure according to RFC 6455, focusing on security requirements.
