This Skill provides complete Cloudflare R2 knowledge for building a secure, S3-compatible object storage layer on Cloudflare's edge network, including bucket configuration, CORS, presigned URLs, and metadata handling.
Use this Skill to create an R2 bucket, configure a Worker binding, and implement basic uploads and downloads at the edge.

Upload files to R2 using the R2 Workers API put() method via a Worker binding. Configure your bucket in wrangler.jsonc, then call env.BUCKET.put(key, body) with the file content and optional metadata like Content-Type and Cache-Control headers.
Yes, use presigned URLs to grant time-limited direct access. Generate a presigned URL server-side with the R2 API, then share it with clients for direct uploads or downloads, reducing server load and improving performance.
Use multipart uploads for resumable, large-file transfers. The R2 Workers API supports multipart operations that let you upload chunks independently, retry failed segments, and resume interrupted uploads without restarting.
Deploy R2 with Cloudflare Workers to serve assets from the edge network. Workers bindings connect to your R2 bucket, enabling fast, geographically distributed asset delivery with built-in caching and content negotiation.
Configure CORS on your R2 bucket to allow cross-origin requests from your domain. Set allowed origins, methods (GET, PUT, POST), and headers in bucket settings so browsers can fetch or upload objects directly.
Yes, R2 stores both HTTP metadata (Content-Type, Cache-Control, Content-Encoding) and custom key-value metadata. Include metadata in put() calls and retrieve it via head() to track object properties without separate databases.
