Crate vercel_rpc_cli 

CLI tool for the vercel-rpc project.

Scans Rust lambda source files for #[rpc_query] / #[rpc_mutation] functions and #[derive(Serialize)] types, then generates TypeScript type definitions and a fully typed RPC client.

Binary

The installed binary is called rpc and provides three subcommands:

• rpc scan — parse a directory and print discovered procedures as human-readable text plus a JSON manifest.
• rpc generate — produce rpc-types.ts (interfaces + Procedures type) and rpc-client.ts (typed RpcClient + createRpcClient factory).
• rpc watch — same as generate, but re-runs automatically whenever a .rs file changes (configurable debounce).

Architecture

┌─────────────┐  scan   ┌──────────┐  codegen  ┌────────────────┐
│  api/*.rs   │ ──────► │ Manifest │ ────────► │ rpc-types.ts   │
│  attributes │  (syn)  │          │ (fmt)     │ rpc-client.ts  │
└─────────────┘         └──────────┘           └────────────────┘

• parser — walks the source directory, parses each .rs file with syn, and builds a model::Manifest.
• codegen::typescript — converts the manifest into a rpc-types.ts file with TypeScript interfaces, enum types, and a Procedures map.
• codegen::client — converts the manifest into a rpc-client.ts file with a typed RpcClient interface and createRpcClient factory.
• watch — wraps generate in a file-watcher loop with debouncing.
