SwissTransfer Proxy for Resumable Uploads

A simple proxy to enable seamless resumable uploads with SwissTransfer.

Why?

SwissTransfer's API currently only supports chunked uploads, making it difficult to use with background URLSession on iOS. This proxy provides:

• A non-chunked upload endpoint as a drop-in replacement for the existing API.
• A foundation for resumable uploads, following RFC Resumable Upload Specification.

The next step is full resumable upload support, allowing out-of-the-box background uploads on iOS.

Getting Started

Server-Side Setup

Run the proxy server (port 8080 is used):

go run main.go

Client-Side Usage

Upload files to this endpoint:

POST /upload?containerUUID=<ContainerUUID>&uploadFileUUID=<FileUUID>

Headers:

• x-upload-host: The upload host for the file transfer.

Roadmap

• ✅ Non-chunked upload proxy
• ⏳ Implement resumable uploads following RFC 9110
