This app is more or less a clone of the flash-invaders app and concept. It has been created for the 50th anniversary of the twinning between the french village La Tessoualle and German village Zwiefalten. The goal is to find some mosaics hidden in La Tessoualle, and answer some quiz each time you scan a new mosaic with the NFC tag stuck on it.

The app is available on the Play Store, and the App Store, under the name "Zwietess".

A web version is available on zwietess.aloiseau.com

This is the v2 version of a webapp I made for the same event, named flash-invaders (now archived).

• Application framework : Tauri (v2)
• Frontend framework : Svelte + TailwindCSS (v5) with SvelteKit
• Frontend components : shadcn-svelte
• NFC scan library : tauri-plugin-nfc
• Backend and auth : Supabase
• Internationalization in French and German, with svelte-kit-i18n

• Clone the repo, and run pnpm install
• Duplicate the .env.example file, rename it to .env, and populate the variables with your own values
• Link your Supabase project and push migrations with supabase db push
• Run pnpm dev to start the app in development mode, or pnpm tauri android|ios dev if you want to run the app.

• For the sake of simplicity, I hardcoded the informations of mosaics and quizs directly in the app, under src/lib/game-data.
• Each NFC tag is encoded with a simple URI such as zwietess:https://invader${ID}, ID being the ID of the mosaic. The app only matches those URIs.
