A low-latency file drop web app
## features - One-to-many transfer of large files - Simple web UI for sender and receivers - Word-based download codes that are easy to remember and communicate - 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 - Rudimentary password authentication for uploading files - Fires a laser beam that turns you trans ## configuration transbeam is configured with the following environment variables: - `TRANSBEAM_STORAGE_DIR`: path where uploaded files should be stored (default: `./storage`) - `TRANSBEAM_STATIC_DIR`: path where the web app's static files live (default: `./static`) - `TRANSBEAM_PORT`: port to listen on localhost for http requests (default: 8080) - `TRANSBEAM_MAX_LIFETIME`: maximum number of days files can be kept for (default: 30) - `TRANSBEAM_MAX_UPLOAD_SIZE`: maximum size of a fileset being uploaded (default: 16G) - `TRANSBEAM_MAX_STORAGE_SIZE`: maximum total size, in bytes, of all files being stored by transbeam (default: 64G) - `TRANSBEAM_MNEMONIC_CODES`: generate memorable download codes using English words, rather than random alphanumeric strings (default: true) - `TRANSBEAM_UPLOAD_PASSWORD`: password for uploading files. This isn't meant to be a hardcore security measure, just a defense against casual internet randos filling up your storage. I strongly recommend setting up fail2ban to throttle password attempts; transbeam logs failed attempts along with IP addresses, in the form `Incorrect authentication attempt from 203.0.113.12`. - `RUST_LOG`: log levels, for the app as a whole and/or for specific submodules/libraries. See [`env_logger`](https://docs.rs/env_logger/latest/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 `TRANSBEAM_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 ```
