Moonblast

Moonlight meets Xbox Fullscreen Experience. A lightweight launcher focused on simple apps launching and streaming using Moonlight.

My main goal is to have lightweight desktop replacement on my streaming only laptop.

Stack

• Frontend: React 19 + TypeScript + Tailwind
• Backend: Tauri 2 (Rust)
• WebView2 for the window
• Device controls run straight through native Win32/WinRT APIs - no daemons, no third-party SDKs

Getting started

npm install
npm run tauri dev      # dev with hot reload
npm run tauri build    # production bundle

Prerequisites: Node 22+ (or Node 20.19+), Rust stable with the MSVC toolchain, Visual Studio 2022 C++ build tools, WebView2.

Note on Windows SmartScreen. Prebuilt installers and binaries are not code-signed in this release. Windows SmartScreen will warn "Windows protected your PC / Unknown publisher" on first launch — click More info → Run anyway to proceed. This is normal for unsigned open-source Windows apps and does not indicate a problem with the binary.

ARM64 build

# one-time - ring needs clang for the ARM64 assembly
winget install LLVM.LLVM

# build
powershell -ExecutionPolicy Bypass -File scripts\build-arm64.ps1
powershell -ExecutionPolicy Bypass -File scripts\build-arm64.ps1 -Destination 'Z:\'

The helper locates Visual Studio via vswhere.exe and resolves clang.exe from your PATH, so it works across VS editions and LLVM install locations.
