Storage Backends

Set STORAGE_BACKEND to choose where files are stored.

Memory

STORAGE_BACKEND=memory  # default

In-memory and ephemeral — files are lost on restart. Good for development and testing.

STORAGE_BACKEND=local
LOCAL_STORAGE_DIR=./storage

Files are written to disk. Make sure the directory exists and is writable. Use a persistent volume in Docker.

STORAGE_BACKEND=gcs
GCS_BUCKET=my-stashy-bucket

Uses Application Default Credentials. In GCE/Cloud Run, this works automatically. Locally, run:

gcloud auth application-default login

For production, use local or gcs. The memory backend is only for development.
