localsend

localsend-ts

A TypeScirpt implementation of the LocalSend protocol

LocalSend provides a documentation for their protocol at https://github.com/localsend/protocol

Readme to the protocol: https://github.com/localsend/protocol/blob/main/README.md

I've seen some implementations in rust

• https://crates.io/crates/localsend
• https://github.com/tom8zds/localsend_rs

I want to build a LocalSend integration extension for my project https://github.com/kunkunsh/kunkun

So I decided to build a TypeScript implementation of the LocalSend protocol.

CLI

Interactive TUI (Recommended)

# Run the sophisticated TUI with real-time device scanning
npm run tui
# or with Bun
bun src/cli-tui.tsx

# With custom port and alias
npm run tui -- --port 8080 --alias "My Device"

The TUI provides a sophisticated interface built with Ink (React for CLI) featuring:

• Real-time device scanning - Continuously discover LocalSend devices
• Device selection - Navigate and select from discovered devices
• Send text messages - Interactive text input and sending
• Send files - File path input with validation
• Receiver mode - Real-time file receiving with progress
• Settings - Dynamic device configuration

Simple Interactive CLI

# Run the basic menu-driven CLI
npm run cli

# With custom settings
npm run cli -- --port 8080 --alias "My Device"

Basic menu interface with:

• Device discovery and selection
• Text and file sending
• Receiver mode with graceful shutdown

Traditional CLI

npx localsend

# Please use a subcommand: send | receive | discover
# Examples:
#   localsend send 192.168.1.100 ./file.txt
#   localsend receive --saveDir ./downloads
#   localsend discover --timeout 10
