trpc-cli

trpc-cli transforms a tRPC (or oRPC) router into a type-safe, documented CLI with zero boilerplate. Current stable version is 0.14.0, released frequently (multiple releases per month). It automatically generates positional arguments, options, help text, and shell completions from Zod/Valibot/Arktype schemas. Unlike general-purpose CLI frameworks like Commander or yargs, trpc-cli leverages tRPC's type system for end-to-end type safety and reuse of router logic across CLI, HTTP server, and programmatic APIs. It depends only on Commander as a runtime dependency (peer deps for validation libraries). Supports tRPC v10/v11, oRPC, and experimental standalone mode. ESM-only since v0.12.0.
