Type-safe RPC in ~300 lines — plain node:http + fetch. Every button below is a POST /trpc/<path> call. Watch the inspector.

Users user.list

    Create user user.create

    Schema: z.object({ name: z.string().min(1) }) — try an empty name to see Zod reject it.

    Find by id user.getById

    Try 1, then 999 (returns null).

    Response inspector raw JSON

    Click anything — the last response lands here.
