# RedwoodJS GraphQL API

RedwoodJS exposes a schema-first GraphQL API powered by GraphQL Yoga and the Envelop plugin system. SDL files (*.sdl.ts) declare types, queries, and mutations while service functions serve as resolvers. Redwood merges them automatically at startup into a single executable schema secured by directive-based authentication enforcement.

**Endpoint:** N/A - library/tooling, no hosted endpoint. Each Redwood application serves its own GraphQL API at `/graphql` (configurable).
