How do I ensure metadata is included when listing R2 objects?

When calling the list() method, you must explicitly opt-in by including 'httpMetadata' or 'customMetadata' in the 'include' array within the options object.

Why does Wrangler return a 403 Forbidden error during R2 operations?

Wrangler requires 'Admin Read & Write' API token permissions. Using 'Object Read & Write' permissions will fail for bucket-level operations performed by the CLI.

Can I use custom domains with presigned URLs in Cloudflare R2?

No, presigned URLs only work with the S3 API domain (r2.cloudflarestorage.com). Custom domains should be used for serving public content, while the S3 domain handles signed access.

Is the CORS configuration format the same for the Dashboard and CLI?

No. The Wrangler CLI requires a JSON structure with a 'rules' array, whereas the Dashboard UI uses a direct array of objects. Mixing these formats will result in configuration errors.

What are the size limits for R2 multipart uploads?

Individual parts must be between 5MB and 100MB, and a single upload can consist of up to 10,000 parts. It is recommended to use standard put() for files under 5MB.

Infraestructura en la Nube

Integrates S3-compatible object storage with Cloudflare Workers to handle file uploads, downloads, and complex asset management at the edge.

Acerca de

The cloudflare-r2 skill provides a comprehensive implementation guide for Cloudflare's zero-egress object storage. It streamlines the development process by offering ready-to-use patterns for standard Workers API operations, multipart uploads for large files, and secure presigned URL generation. Beyond basic CRUD operations, the skill addresses critical implementation hurdles such as CORS configuration discrepancies between the CLI and Dashboard, specific API token permission requirements, and robust retry logic to ensure application resilience during platform outages.
