When Your FlatList Starts Stuttering: Migrating Rork Apps to FlashList v2
When your Rork app's long lists start feeling sluggish, migrating to FlashList v2 makes scrolling dramatically smoother. Here is the practical migration path, taking advantage of v2's removal of estimatedItemSize.
Skeleton Screens in Rork Apps — Practical Patterns for Better Perceived Performance
If your Rork app still shows a spinner on a blank screen during load, you are leaving a lot of perceived performance on the table. Here is how I drop skeleton screens and shimmer effects into Rork-generated React Native code without over-engineering it.
The Machine Learning Optimizations Rork Runs Behind the Scenes — Why Generated Apps Just Feel Faster
Have you noticed Rork-generated apps run smoother than equivalent code you wrote yourself? Multiple ML pipelines are at work behind the scenes. This guide breaks down what's happening at code-gen, build, and runtime — backed by my own benchmarks.
The 5 Machine Learning Optimizations That Make Rork's AI Code Generation Fast
Why does Rork generate code faster and more reliably than other AI app builders? After three months of measuring and observing, here are five machine learning optimizations quietly working behind the scenes.
Practical Techniques to Cut the Startup Time of Rork-Generated Apps
If a Rork-generated app feels sluggish on launch, the cause is almost always in how initial loading is assembled. Here's the exact process I used to cut startup time to a third of its original value, measurements included.
Rork App Freezing and Not Responding: A Pattern-by-Pattern Troubleshooting Guide
Troubleshoot Rork apps that freeze or stop responding to user input. Covers four common causes: main thread blocking, useEffect infinite loops, missing loading states, and FlatList key issues—with code examples and fixes.
