Monorepo LangGraph Image Builder

Build a helper that produces a Docker image for a JavaScript LangGraph service that lives inside a monorepo, wiring in custom install/build commands so the correct workspace packages are available.

Capabilities

Monorepo context handling

• Uses the provided workspace root as the Docker build context while generating or updating the LangGraph config in the service directory so the supplied graph entry is registered and shared packages remain visible. @test

Custom install and build commands

• Forwards the caller-supplied install and build commands to the image build so workspace-specific steps (e.g., filtered package installs) run instead of defaults. @test

Node-only configuration

• Ensures the generated configuration includes the expected Node version for the service and does not inject Python settings. @test

Tag and build argument propagation

• Applies the requested image tag and any extra Docker build arguments when invoking the build. @test
