S3-compatible storage seam: presigned uploads, signed downloads, optional public CDN target. Provider-agnostic, edge-runtime safe, zero framework deps.
A Cloudflare Worker that proxies requests to a private AWS S3 bucket hosting a static web application. The bucket never needs to be made public; the Worker signs every request using AWS Signature V4 via aws4fetch.
Add a description, image, and links to the aws4fetch topic page so that developers can more easily learn about it.
To associate your repository with the aws4fetch topic, visit your repo's landing page and select "manage topics."
