LunchCrew

LunchCrew is a small web app for teams deciding where to eat lunch together. It gives a crew a reusable invite link, a daily ballot, nearby place suggestions, lightweight identity, and a simple history of past winners.

Stack

• Next.js 15
• React 19
• TypeScript
• Tailwind CSS 4
• Supabase
• Supabase Edge Functions for places lookup and Stripe flows

What It Does

• Creates or restores a crew from a shareable invite code
• Generates a fresh lunch poll for the current UTC day
• Lets teammates add places manually or from nearby suggestions
• Syncs votes live with Supabase realtime, with polling fallback
• Stores lightweight member names per device
• Tracks recent winners and a simple leaderboard
• Supports optional founding-plan checkout via Stripe

Local Setup

1. Install dependencies

npm install

2. Create local env vars

cp .env.example .env

3. Fill in the required values

• Client-side:
  • NEXT_PUBLIC_SUPABASE_URL
  • NEXT_PUBLIC_SUPABASE_ANON_KEY
• Server-side / Edge Functions:
  • GOOGLE_MAPS_API_KEY
  • SUPABASE_URL
  • SUPABASE_SERVICE_ROLE_KEY
  • LUNCHCREW_BASE_URL
  • STRIPE_SECRET_KEY
  • STRIPE_WEBHOOK_SECRET

EXPO_PUBLIC_* vars are only kept for backward compatibility in the codebase and are not required for the web app.

4. Apply the database schema in Supabase

• Run supabase.sql

5. Start the app

npm run dev

Supabase Functions

This repo includes Edge Functions under supabase/functions:

• places-proxy
• stripe-create-checkout
• stripe-webhook

Those functions require server-side secrets. Do not expose service role, Stripe secret, webhook secret, or Maps API keys in client-side env vars or frontend code.
