Why Your Rork App's Stripe Webhooks Drop Events Only in Production — Field Notes on Idempotency, Retries, and Out-of-Order Delivery
A field-tested four-layer design for stabilizing Stripe webhooks that pass locally but silently misfire in production: signature verification on Workers, event-ID idempotency, fast-2xx-then-process, and a reconciliation job that survives out-of-order delivery. Built around Cloudflare Workers and KV.
I Initialized Ads Before Restoring Purchases, and Paying Users Saw a Banner Flash — Cold-Start Ordering for Rork (Expo) Apps
Consent, ATT, ad SDK init, purchase restore, and remote config all try to run in the same few hundred milliseconds at launch. Get the order wrong and a paying user sees a banner flash, or measurement fires before consent in the EEA. Here is how I fold a Rork-generated Expo app's startup into a single orchestrator and kill the races by design.
Controlling HomeKit Accessories from Your Rork Max Native App — Permission and State-Sync Lessons from Indie Shipping
A walkthrough of adding HomeKit to the native Swift app Rork Max generates: listing and controlling accessories, from the permission dialog wording to the state-sync traps. Covers the territory React Native struggles to reach, from a working indie developer's perspective.
Keeping Expo Push Tokens from Slipping Through the Cracks in Production
After adding re-engagement push to a Rork-generated Expo app, the delivered count came in well below the active install count. The cause was missed token updates and stale tokens left to pile up. Here is the lifecycle I settled on, with code: registration, refresh, server storage, and pruning.
Adding SwiftData to a SwiftUI App Generated by Rork Max
Rork Max can produce polished SwiftUI screens, but persistence often stops at @State. Here is how I layer SwiftData onto generated code: model design, wiring the container to views, and a schema migration pattern that survives shipping.
Keeping Login Alive in a Rork-Built Expo App — Preventing Token-Refresh Races with Single-Flight
Add login to the Expo app Rork generates and it works at first, but in production the 'I got logged out on my own' reports creep in. Most are token-refresh races. This covers a reliability design that single-flights refresh, stores tokens safely, and handles expiry correctly.
Designing Apps That Keep Working When the Signal Drops — Optimistic Updates and Resolving Conflicts on Reconnect
Make the Expo apps you build with Rork keep responding even when the signal drops in a subway or elevator. We assemble optimistic updates that move the screen first, and conflict resolution that reconciles when the connection returns, in working code.
Exposing Your Rork Max App to Siri and Shortcuts with App Intents
How to add App Intents to a Swift app generated by Rork Max so Siri and Shortcuts can invoke your actions, from registering an AppShortcut to the production gotchas, with real code.
The Users You Cut Off as Churned Were Still Willing to Pay — Implementing Grace Periods That Keep Access Alive
A failed renewal is not a cancellation. If you revoke access during the grace period, you throw away recoverable revenue. Here is how to tell grace, billing retry, account hold, and real churn apart in a Rork (Expo) app, keep access during grace, and guide users back.
Running a Neon + Drizzle Backend for Your Rork App in Production — Notes on Edge Connections, Zero-Downtime Migrations, and Type-Safe Queries
After wiring Neon Serverless Postgres and Drizzle ORM into a Rork app's backend, the friction shows up in production. These are implementation notes on choosing an edge connection model, migrating without locking tables, and designing type-safe queries that don't balloon into N+1.
Stopping the Slow Drift of Colors and Spacing on Every Regeneration with a Single Source of Design Tokens
Every time Rork regenerates a screen, button colors and spacing shift a little. Here is a design that freezes your tokens in one place and steers generated output to always reference them.
Drawing the Line Between Rork Max's Swift Output and the Expo Build
Rork Max now generates native Swift, while the standard Rork keeps producing Expo (React Native) apps. Here is how to split responsibilities between the two engines inside a single app business, viewed from real maintenance cost.
