Type-Safe WebSockets Without Boilerplate: Fitz's Auto-Generated APIs

Fitz demonstrates a paradigm shift in real-time API development by combining typed WebSocket support with automatic AsyncAPI schema generation, eliminating boilerplate and reducing external dependencies. Rather than bolting on Socket.IO or Redis pub/sub, developers define type-safe real-time endpoints as methods with validation and documentation handled automatically. This reflects a broader industry trend toward frameworks treating real-time communication as a first-class citizen rather than an afterthought.
