handler-storage-r2

Upload files to R2 by configuring AWS CLI v2 with your R2 endpoint, bucket name, and credentials, then use the upload operation to push files to your bucket. The handler validates inputs and returns structured JSON results confirming successful storage.

Yes, presigned URLs enable temporary public access to R2 files without exposing credentials. The handler generates time-limited URLs or permanent public URLs depending on your access requirements.

You need AWS CLI v2 installed, R2 endpoint configuration, a bucket name, and valid Cloudflare R2 credentials set as environment variables. The handler expands these variables and validates all inputs before executing storage operations.

R2 supports complete file lifecycle management: download files to local storage, delete objects from the bucket, and list bucket contents. All operations validate inputs and return structured results without logging sensitive information.

Yes, streaming read operations allow you to access R2 file contents directly. This approach streams data without intermediate storage, reducing latency for applications that process files in-place.

Presigned URLs provide time-limited, credential-free access to specific files without exposing your R2 credentials or making entire buckets public. Use them for secure file sharing, temporary downloads, or controlled user access scenarios.
