Mobile App Base

This repository contains an Expo-managed React Native starter configured with TypeScript, React Navigation, and Supabase auth scaffolding. It includes placeholder screens for upcoming features and uses Supabase session state to control navigation.

Prerequisites

• Node.js (LTS recommended)
• npm (bundled with Node.js)
• Expo CLI (installed automatically via npm scripts)

Setup environment variables

1. Copy the example file and fill in your Supabase project values:

   cp .env.example .env
   

2. Set EXPO_PUBLIC_SUPABASE_URL and EXPO_PUBLIC_SUPABASE_ANON_KEY with your Supabase project credentials.
3. Optional: set EXPO_PUBLIC_TEST_EMAIL and EXPO_PUBLIC_TEST_PASSWORD to enable the placeholder test sign-in button.

Install dependencies

npm install

Run the app

Start the Expo development server:

npm start

You can also target specific platforms:

npm run android
npm run ios
npm run web

Open on a physical device

1. Install the Expo Go app from the iOS App Store or Google Play Store.
2. Ensure your device and development machine are on the same network.
3. Run npm start and scan the QR code displayed in the terminal or Expo Dev Tools using Expo Go.
4. The app will load on your device with live reload enabled.

Deploy the Gemini-powered Edge Function

1. Ensure the Supabase CLI is installed and authenticated.
2. Set the Gemini API key as a Supabase secret (never store it in the Expo app):

   supabase secrets set GEMINI_API_KEY=your-gemini-api-key
   

3. Deploy the function:

   supabase functions deploy generate-recipe
   

4. Confirm the function is callable with your Supabase project and that authentication is configured (the Expo app uses the authenticated Supabase session when invoking the function).

Run the app locally

1. Ensure your .env file is configured (see above) and that the Supabase Edge Function has been deployed to your project.
2. Start the Expo server with npm start.
3. Use the “Fitness recipe (text)” button on the Home screen to open the new flow, and the function will be invoked via Supabase Functions without exposing the Gemini API key to the client.
