FAQ

  • How are input types inferred on the client?

    • The first parameter of each @Route() method is treated as the input type. InferNestRpcRouterApp maps that to the client.

  • Can I decorate the first parameter?

    • No. Index 0 is reserved for input and enforced at runtime.

  • How do I access the Nest request/response?

    • Use built-ins: Req, Res, Next, or create custom param decorators.

  • Does batching change execution order?

    • Calls are executed in parallel on the server and returned in a correlated response array; each client call receives its own result or error.
