How does ElysiaJS handle WebSocket and HTTP routing for production APIs?

ElysiaJS handles WebSocket and HTTP routing by providing scalable backend patterns across both protocols. It enforces safety through lifecycle hooks and guards, ensuring production-ready API performance and structured error management.

Can I use ElysiaJS plugins for authentication and OpenAPI generation?

Yes, you can use ElysiaJS plugins for authentication, OpenAPI, CORS, websockets, and deployment strategies. This rich plugin ecosystem allows rapid integration of essential backend features without writing repetitive boilerplate.

What is the best way to validate input and output in a TypeScript backend?

The best way to validate input and output in a TypeScript backend is using Elysia's TypeBox-based schema system. It provides complete request validation and enforces type safety from routing to runtime, reducing development errors.

Does ElysiaJS support lifecycle hooks and macros for backend error handling?

Yes, ElysiaJS supports lifecycle hooks and macros for backend error handling. These features enforce safety and provide real-world patterns for production-grade APIs, ensuring structured error management across your application.

When do I need runtime validation and lifecycle guards in backend routing?

You need runtime validation and lifecycle guards in backend routing when building scalable, production-grade APIs. ElysiaJS uses these mechanisms to enforce safety, manage structured errors, and prevent runtime failures across HTTP and WebSocket connections.
