Cross-platform restaurant selector app built with Tauri + Alpine.js.

Hats off to the OG Python version by @zookinheimer 🎩

Development

Prerequisites

1. Install Node.js and Rust:

   mise install

   If you encounter GPG signature verification errors, import the Node.js release key:

   gpg --keyserver hkps://keys.openpgp.org --recv-keys 86C8D74642E67846F8E120284DAA80D1E737BC9F

2. Install dependencies:

   npm install

3. Install iOS targets (for mobile development):

   rustup target add aarch64-apple-ios x86_64-apple-ios aarch64-apple-ios-sim

4. Install ios-deploy (for physical device deployment):

   brew install ios-deploy

5. Setup iOS Simulator (for simulator development/testing):

   • Simulators are automatically available in Xcode
   • Default simulator: iPhone 13 mini (iOS 18.6)
   • To add more simulators:
     • Open Xcode → Window → Devices and Simulators
     • Click + (Plus sign) at bottom left
     • Select Device Type and OS Version
     • Click Create
   • To change the default simulator, edit IOS_SIM_DEVICE in .env

6. Configure Apple Developer account (for iOS device builds only):

   • Not required for simulator builds (task ios:dev or task ios:build:sim)
   • Required for device builds and App Store distribution
   • Open Xcode → Settings → Apple Accounts → Add your Apple ID
   • Connect an iOS device or manually add device IDs at developer.apple.com/account
   • The Taskfile will automatically initialize the iOS project when needed

Running the app

Using Taskfile (recommended)

# Development (macOS) - uses nightly + parallel frontend (~10% faster)
task dev

# Development (macOS) - stable toolchain fallback
task tauri:dev:stable

# Development (iOS simulator)
task ios

# Development (physical iOS device)
task ios:run:device

# Run tests
task test

# Build (macOS - current architecture)
task build

# Build (macOS - Apple Silicon)
task build:arm64

# Build (macOS - Intel)
task build:x64

# Build (iOS for App Store - requires device/provisioning)
task ios:build

# Build (iOS Simulator - no provisioning required)
task ios:build:sim

# Sync code signing certificates
task certs

# Upload to TestFlight
task ios:testflight

# Upload to App Store
task ios:release

# Development (Android emulator)
task android:dev

# Development (physical Android device - hot-reload)
task android:dev:device

# Build and install on physical Android device (standalone APK)
task android:run:device

# Build (Android APK for sideloading)
task android:build:apk

# Build (Android AAB for Google Play)
task android:build:aab

# Upload to Google Play Store beta track
task android:testflight

# Upload to Google Play Store production
task android:release

# Clean build artifacts
task clean

Using npm/npx directly

# Development (macOS)
npx tauri dev

# Development (iOS simulator)
cd src-tauri && npx tauri ios dev

# Build (macOS)
npx tauri build

# Build (iOS)
cd src-tauri && npx tauri ios build

# Development (Android emulator)
cd src-tauri && npx tauri android dev

# Build (Android)
cd src-tauri && npx tauri android build
