Client
======

Both SDKs expose a ``Client`` entry point for the appliance gRPC control plane.
Python owns its channel directly; TypeScript accepts a Connect transport from
the runtime-specific entry points.

         :value: '127.0.0.1:50151'

         Default gRPC target when ``Client()`` is called without one and
         :envvar:`OLO_SDK_GRPC_TARGET` is unset.

      .. py:data:: ENV_TARGET
         :module: olo
         :value: 'OLO_SDK_GRPC_TARGET'

         Environment variable that overrides :data:`olo.DEFAULT_TARGET`.

      ``olo`` exports a runtime-neutral ``Client`` and channel helpers.

      - :doc:`Client </typescript/api/generated/olo/classes/Client>` — entry
        point for the TypeScript SDK; exposes the ``core``, ``spatial``,
        ``kinematics``, ``locomotion``, ``navigation``, ``vision``, and ``ai``
        module wrappers plus ``robot()``.
      - :doc:`Robot </typescript/api/generated/olo/classes/Robot>` —
        namespace-scoped robot handle with always-present capability handles;
        operations validate their own runtime dependencies.
      - :doc:`DEFAULT_TARGET </typescript/api/generated/olo/variables/DEFAULT_TARGET>`
        — default appliance gRPC target.
      - :doc:`ENV_TARGET </typescript/api/generated/olo/variables/ENV_TARGET>`
        — environment variable that overrides ``DEFAULT_TARGET`` for target
        resolution in Node.

      Construct ``Client`` with a Connect transport for your runtime:

      .. code-block:: typescript

         import { Client } from "olo";

         const client = new Client(myTransport);
