## 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
|
|
- Can also download individual files out of an uploaded collection
|
|
- 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_BASE_URL`: base URL for this transbeam instance, without
|
|
trailing `/`
|
|
- `TRANSBEAM_PORT`: port to listen on localhost for http requests
|
|
(default: 8080)
|
|
- `TRANSBEAM_REVERSE_PROXY`: whether transbeam is running behind a
|
|
reverse proxy (recommended), or directly exposed to the internet. If
|
|
true, transbeam will only bind to localhost, and will use the
|
|
`Forwarded` or `X-Forwarded-For` headers to determine client IP
|
|
addresses for logs. If false, transbeam will bind on all interfaces,
|
|
and will always log the peer IP address. (default: true)
|
|
- `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 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`.
|
|
- `TRANSBEAM_CACHEBUSTER`: query string that will be appended to CSS
|
|
and JS files, to force re-fetching of cached files when needed.
|
|
- `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. `TRANSBEAM_CACHEBUSTER` is set automatically to a hash of the
|
|
static files' store path, so it will change whenever the static files
|
|
change.)
|
|
|
|
### non-nix
|
|
|
|
```
|
|
git clone https://git.xeno.science/xenofem/transbeam
|
|
cd transbeam
|
|
cargo run --release
|
|
```
