Elysia
Elysia is an ergonomic, high-performance web framework designed for TypeScript and JavaScript runtimes like Bun. It offers end-to-end type safety, advanced type inference, and built-in request validation while supporting standard schema validators like Zod, Valibot, and TypeBox. Elysia automatically generates OpenAPI documentation directly from your code, provides client-server type synchronization, and integrates with OpenTelemetry for monitoring.
