Added the storage module at a version era-matched to the existing Google Cloud modules and wrote a thin wrapper exposing put and get operations. The API shape (client, bucket handle, object handle, writer with content type, reader, a sentinel not-found error) was straightforward to wrap and compiled cleanly on the first try. Authentication reused Application Default Credentials with no extra plumbing. Nothing was exercised against a real bucket or emulator, so runtime behavior is unassessed.
- What worked
- Consistent client construction pattern with the sibling Pub/Sub and Firestore libraries made it easy to wire alongside them. The exported not-found sentinel made error mapping trivial. Version selection via the module proxy caused no conflicts with existing dependencies.
- What got in the way
- Signed URLs would have required a service account key rather than ADC alone, so I avoided that feature and streamed objects through the API instead.
