Build guide

1. 01Project Scaffolding & Database Schema

   Initialize the monorepo structure with a Next.js web frontend and an Expo React Native mobile app. Set up Turso database with tables for users, home_airports, flight_deals, and user_alerts.

   Scaffold a monorepo containing a Next.js app in /web, a backend worker service in /worker, and an Expo React Native app in /mobile. Configure Turso SQLite with Drizzle ORM. Create tables for users (id, email, subscription_tier), home_airports (id, user_id, airport_code), flight_deals (id, origin, destination, price, original_price, airline, departure_date, return_date, is_mistake_fare, created_at), and user_alerts (id, user_id, deal_id, sent_at). Ensure TypeScript types are fully generated and enforce strict type safety across all workspaces.

2. 02Authentication & User Preferences

   Implement authentication using better-auth and build user settings screens for selecting home airports and deal destination preferences.

   Implement email/password authentication using better-auth integrated into the Next.js backend and shared across the Expo mobile app via API clients. Build a settings screen on both web and mobile that allows authenticated users to select multiple home airports (e.g., JFK, SFO) and specify their cabin class preference (economy, premium_economy, business_class). Store these preferences in user-associated tables and create API endpoints to fetch and update them.

3. 03Flight Data Ingestion Pipeline

   Build a background worker script that mocks or fetches incoming flight price data feeds and populates the flight_deals table.

   Create a background worker script in the /worker service running on a cron schedule. Implement a modular provider interface that can ingest flight pricing data either from public aviation APIs or structured mock feeds. Parse incoming pricing records, normalize origin and destination airport codes, calculate discount percentages relative to historical averages, and insert valid records into the flight_deals table. Include robust error handling and rate-limit management for external HTTP requests.

4. 04Deal Filtering & Anomaly Detection Engine

   Develop the core filtering algorithm that evaluates flight deals against user preferences and flags significant price drops or mistake fares.

   Develop a filtering and matching engine service that runs after every flight data ingestion batch. The engine must query active flight deals, compare prices against historical thresholds for specific routes, and flag deals with discounts exceeding 40% or obvious pricing errors as mistake fares. Filter deals matching user home airports and subscription tiers (e.g., economy-only for Free/Premium users, business class for Elite users), generating pending notification queue items.

5. 05Multi-Channel Notification Dispatcher

   Wire up Resend for email alerts and OneSignal or Expo push notifications to dispatch deal alerts to users.

   Build a notification dispatcher service that processes the pending notification queue. Integrate Resend for sending beautifully styled HTML email alerts containing deal summaries, direct airline booking links, and pricing details. Integrate OneSignal or Expo push notification services to dispatch real-time alerts to the mobile app clients. Implement idempotency checks to ensure users never receive duplicate alerts for the same deal ID.

6. 06Web Dashboard & Mobile Feed UI

   Build the user-facing interfaces on web and mobile to browse active deals, view deal details, and manage subscriptions.

   Build the deal feed UI in both the Next.js web app and the Expo mobile app. The interface must display a chronological list of active flight deals filtered by the user's home airports, featuring destination imagery, price drop badges, airline names, and direct booking CTA links. Include search filters by region and cabin class, along with a subscription upgrade page outlining Free, Premium, and Elite tiers.
