SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

It helps you turn a React Native (Expo) + Supabase app into a production-ready system by covering reliability, security, and key launch requirements like crash reporting, payments, push notifications, deep links, and offline behavior.

Core Features & Use Cases

  • Global error handling for a better user experience, including Supabase/network error handling and user-friendly fallback UI.
  • Security hardening through stricter Supabase RLS policy design, Zod input validation, safer API/secrets management, and robust session/token handling.
  • Production observability & resilience with crash reporting (Sentry/Crashlytics) and offline-first behavior using caching plus network state awareness.
  • Launch-ready integrations for payments (Google Play Billing + restore + syncing to Supabase), push notifications (FCM + token storage + server notifications), and deep links (Expo scheme + universal links guidance).

Quick Start

Ask the AI to generate the production hardening changes for your Expo (React Native) app using Supabase: global ErrorBoundary, RLS/input validation/security/session improvements, Sentry/Crashlytics setup, offline caching with NetInfo, FCM push wiring, deep link configuration, and in-app purchase/subscription flow synced to Supabase.

Frequently Asked Questions about production-hardening

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I harden a React Native Expo app with Supabase for production?▼

Production hardening for React Native (Expo) + Supabase requires implementing global ErrorBoundary fallbacks, Zod input validation, strict RLS policies, Sentry crash reporting, offline caching with network-aware syncing, and FCM push wiring to prevent crashes and security gaps.

What is needed to configure Sentry crash reporting and offline caching in a Supabase React Native app?▼

Configuring Sentry crash reporting and offline caching in a Supabase React Native app requires initializing Sentry for production observability and using NetInfo for network state awareness. This enables offline-first behavior with caching and automatic syncing when connectivity returns.

How do I sync Google Play Billing in-app purchases with Supabase in React Native?▼

Syncing Google Play Billing in-app purchases with Supabase requires implementing the billing and purchase restoration flow in your React Native app, then synchronizing the verified purchase and subscription states directly to your Supabase backend database.

Does this production hardening approach handle FCM push notifications and deep links for Expo apps?▼

Yes, this production hardening approach handles FCM push notifications and deep links for Expo apps. It covers FCM token storage with Edge Function server sends, alongside deep link scheme and universal links wiring to ensure launch-ready integrations.

How do I improve Supabase RLS policies and session security for a mobile app?▼

To improve Supabase RLS policies and session security for a mobile app, design stricter Row Level Security policies, implement robust session and token handling, and apply Zod input validation. Safer API and secrets management further hardens the overall security posture.

What is the best way to handle Supabase network errors in React Native production apps?▼

The best way to handle Supabase network errors in React Native production apps is implementing global ErrorBoundary fallbacks with user-friendly UI. Combined with offline caching and network-aware syncing, this ensures end-to-end reliability during real-world network failure modes.
