My Ads Never Came Back After a Subscription Expired: Fixing the Direction of an Ad-Free Check
An ad-free flag stayed on after the subscription expired because the check pointed the wrong way. Here is how I rebuilt it to wait for two purchase queries, decide only from confirmed facts, and keep the last value on failure.
Designing Seams That Survive AI Regeneration in Rork
Every follow-up prompt to Rork can quietly wipe out logic you wrote by hand. Protecting it with prompts is a patch, not a fix. Here is how to separate generated code from code you own, and draw a boundary that regeneration cannot reach, with working Zustand and service-layer examples.
Three Implementations You Always Face with Next.js and Supabase — RLS, State, and Real-Time
Past building the foundation of a web app lie three things you always get stuck on — DB access control (RLS), screen state management, and real-time updates — explained at the implementation level with Next.js and Supabase code. Down to production pitfalls like memory leaks from forgotten unsubscribes and how auth ties into RLS.
Add Long-Press Drag Reordering to Your Rork Favorites List Without the Jank
A practical walkthrough for retrofitting long-press drag reordering onto a Rork-generated favorites list: keeping re-renders down, respecting the worklet boundary, persisting the order, and avoiding ghost cards and scroll conflicts.
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.
The Day a Third Reason to Hide Ads Appeared — Folding Rork App Ad-Free Logic Into One Place
Ads show only on one screen for paying users, or ads never show for free users. The usual cause is that the condition for hiding ads is scattered across the code. Here is how I fold three reasons — subscription, lifetime purchase, and a timed reward unlock — into a single state and route every ad through one hook, written as an implementation note from running six apps as an indie developer.
Rork FlatList Crashes from Direct State Mutation – Defensive Copy Fix
FlatList crashes in Rork-generated code are often caused by direct array mutation. Learn the defensive copy pattern that eliminated 50+ crashes in 28 days from a 50M-download app's v2.1.0 update.
Switching from Context API to Zustand v5 in Rork Apps: What Changed and Why It Worked
Context API caused cascading re-renders in a growing Rork app. Here's how migrating to Zustand v5 solved it — with practical patterns for auth state and async logic in React Native.
Growing Rork-Generated React Native Code Into Something Production Can Hold
Learn how to identify the six most common technical debt patterns in Rork-generated React Native code and transform them into production-ready quality through TypeScript safety, component splitting, state management, async patterns, performance tuning, and testability — all with real Before/After examples.
Fix Disappearing Characters and Jumping Cursors in Rork TextInputs (3 Patterns)
Three state-related patterns that cause TextInput characters to vanish or cursors to jump in Rork-generated React Native apps, with the exact code changes that fix each one.
State Updated in Rork But UI Won't Re-render? Five Patterns and Fixes
setState is firing in your Rork-generated code but the UI refuses to update. Five common root causes — mutation, stale closures, Zustand selectors, missed dependencies, unmounted updates — each with Before/After code.
