Tinder-style restaurant swiping MVP (Expo + React Native + Firebase).

Current status

This repository now includes:

• MVP swipe UI in App.js
• Firestore schema docs in docs/firestore-schema.md
• Project roadmap in docs/technical-roadmap.md

1) Prerequisites

• Node.js 18+
• npm 9+
• Expo Go app on your phone (optional, easiest way to test)
• Firebase project (Auth + Firestore enabled)
• Google Places API key

2) Install dependencies

npm install

3) Configure environment variables

Create a .env file in the repo root:

cp .env.example .env

Fill in all values:

• EXPO_PUBLIC_FIREBASE_*
• EXPO_PUBLIC_GOOGLE_PLACES_API_KEY

4) Set a real session ID

In App.js, replace:

const [sessionId] = useState("REPLACE_WITH_SESSION_ID");

with a valid Firestore session document ID.

Quick test path: manually create a sessions/{sessionId} document matching docs/firestore-schema.md.

5) Run the app

Start Expo:

npm run start

Then choose one:

• Press a for Android emulator
• Press i for iOS simulator (macOS only)
• Scan QR code with Expo Go on a phone

Note about branch update tools

Some hosted branch editors/tools reject commits that contain binary files (for example PNG assets) and show "Binary files are not supported". This repo is configured to run without committed binary assets by default. If you want custom app icons/splash screens, add image files later and point app.json to them in your own branch/tooling.

Common issues

• Blank cards / no restaurants: check location permissions and Google Places key restrictions.
• No matches appearing: ensure both users are writing likes to the same sessions/{sessionId} document and both UIDs are in participants.
• Firebase auth null UID: make sure you implement an auth bootstrap (e.g., anonymous sign-in) before swiping.

Next required wiring

For a fully runnable flow, add:

1. Session create/join screen to generate & enter a 4-digit code.
2. Anonymous auth bootstrap on app launch.
3. Persist fetched restaurants to sessions.restaurants so both users swipe the same list.
