transbeam

A low-latency file drop web app

features

• One-to-many transfer of large files
• Simple web UI for sender and receivers
• Receivers can begin downloading immediately, without needing to wait for the upload to finish
• Receivers can also download after the upload is complete and the sender has gone offline
• Easy to send multiple files at once - they're bundled into a zip file for receivers, with zero compression so extraction is quick
• Sanitises filenames, using sensible non-obnoxious defaults that should be safe across platforms
• Fires a laser beam that turns you trans

configuration

transbeam is configured with the following environment variables:

• STORAGE_DIR: path where uploaded files should be stored (default: ./storage)
• STATIC_DIR: path where the web app's static files live (default: ./static)
• PORT: port to listen on localhost for http requests (default: 8080)
• RUST_LOG: log levels, for the app as a whole and/or for specific submodules/libraries. See env_logger's documentation for details.

running

nix flakes

nix run git+https://git.xeno.science/xenofem/transbeam?ref=main

(The Nix package is wrapped with STATIC_DIR set automatically to the correct Nix store path, so it'll serve the static files properly no matter what directory you run it from.)

non-nix

git clone https://git.xeno.science/xenofem/transbeam
cd transbeam
cargo run --release
