🚀 Key Features

* Framework Agnostic No Dependency Injection (DI) containers required. Effortlessly integrate with Express, NestJS, AdonisJS, or full-stack frameworks like Next.js, Nuxt, and TanStack Start.
* Runtime Portability Leverages the Adapter Pattern to decouple your logic from the runtime. Switch between Node.js, Cloudflare Workers (Durable Objects), or AWS Lambda without rewriting core logic.
* Test-Driven Excellence Every component includes a built-in "in-memory" adapter. Run unit tests instantly without spinning up databases or external infrastructure.
* Type Safety & DX Deep IntelliSense support and strict type-safety. Designed for auto-imports and modern developer workflows.
* Standard Schema Support Native integration with Standard Schema, allowing you to use Zod, Valibot, or ArkType for unified runtime validation.
