Type-Safe Real-time Communication: How Fitz Eliminates WebSocket Complexity

Fitz demonstrates how moving serialization into the type system eliminates boilerplate that developers typically spell out manually—JSON parsing, validation, and error handling become compile-time concerns. By catching malformed messages at compile-time rather than runtime, the framework significantly improves developer experience and reduces bugs in real-time systems. This represents a broader architectural shift: APIs where the type system, not the framework, enforces correctness and safety.
