QuickDrop

A Windows-first, AirDrop-style LAN file transfer application built with Tauri 2 + React + Rust. This repository is currently at Step 1 of the build plan (project scaffolding). All domain logic (discovery, pairing, transfer engine, file handling) lives in the quickdrop-core crate and is implemented incrementally in subsequent steps.

Prerequisites

• Rust (stable, MSVC toolchain) — rustup show should list stable-x86_64-pc-windows-msvc.
• MSVC C++ Build Tools with the Windows SDK (required by the Rust MSVC linker). Install via the Visual Studio Installer → "Desktop development with C++".
• Node 20+ and Yarn 1.x (Classic).
• WebView2 Runtime (preinstalled on Windows 11).

First-time setup

From the quickdrop/ directory:

yarn install

Run in development

yarn tauri dev

Logs: %APPDATA%\QuickDrop\logs\quickdrop.log. Filter with QUICKDROP_LOG env var, e.g. QUICKDROP_LOG=debug,sled=warn.

Build a release MSI

yarn tauri build

Produces an MSI under src-tauri/target/release/bundle/msi/.

Runtime data locations

Purpose	Path
Settings, DB, logs	%APPDATA%\QuickDrop\
Default receive folder	C:\QuickDrop\
Identity keypair	Windows Credential Manager (added in Step 3)

Build plan

1. ✅ Scaffold (Tauri 2 + React + TS, workspace, plugins, tray, logging)
2. Identity + TrustStore (Ed25519 in Credential Manager)
3. Discovery service (mDNS + UDP fallback)
4. TLS transport with fingerprint pinning
5. Wire protocol + framed messaging
6. Streaming I/O + backpressure + progress events
7. Resume + atomic writes + duplicate handling
8. Receiver service hardening
9. Pairing UX (SAS dialog, trust persistence)
10. Windows context menu integration (--send CLI, registry installer)
11. Packaging + auto-start + uninstall cleanup
12. Test matrix (large files, network drops, multi-device)
