Browser-compatible file transfer CLI and TUI built with Bun, WebRTC, and Rezi.

• Bun >= 1.3.11

bun add -g @elefunc/send

send
send peers
send offer ./file.txt
send accept
send tui

When no subcommand is provided, send launches the TUI by default.

--room is optional on all commands. If you omit it, send creates a random room and prints or shows it.

In the TUI, the room row includes a 📋 invite link that opens the equivalent web app URL for the current committed room and toggle state. When a peer filter is active, that invite link also carries the current filter.

Not every command has a flag-for-flag TUI dual. CLI automation stays command-specific:

• peers: --wait, --json
• offer: --to, --wait-peer, --json
• accept: --from, --N, --json

Save-path controls only matter where incoming files are written, so --folder and --overwrite are relevant on accept and tui.

--self accepts three forms:

• name
• name-id
• -id using the attached CLI form --self=-ab12cd34

SEND_SELF supports the same raw values, including SEND_SELF=-ab12cd34.

The id suffix must be exactly 8 lowercase alphanumeric characters.

send peers --self alice
send offer ./demo.txt --self alice-ab12cd34
send accept --self=-ab12cd34
send accept --from alice --N 1
send tui --filter bob-p2
SEND_SELF=-ab12cd34 send tui

bun install
bun run typecheck
bun test

The package is Bun-native and keeps its runtime patches in runtime/.
