Visualizing the Dual-Thread Model of Lynx JS

If you’ve felt JS thread pressure in React Native, Lynx’s runtime will feel familiar and different at the same time. This article uses a simple jammer technique inspired by React Native experiments to reset expectations and provide a clear mental baseline. From there, it shows how Lynx’s dual-thread model keeps UI-critical work responsive, even when background JavaScript is completely blocked.

Why You Don’t Have to Minify JavaScript Code in React Native Apps

JavaScript minification is standard practice on the web, but React Native follows a different optimization path. This article explains how the Hermes engine compiles JavaScript into bytecode and applies dead code elimination during that step, making traditional minification largely unnecessary. It also shows how to verify what actually ships in production by decompiling Hermes bundles.

Profiling MLC-LLM’s OpenCL Backend on Android: Performance Insights

MLC-LLM can run LLMs fast on-device, but we hit a nasty Android issue: the first inference froze the system UI for up to 50 seconds, then everything was fine. This post walks through how we added Perfetto-compatible traces in MLC-LLM and kernel profiling in TVM/OpenCL, and why switching from _1 to _0 model formats fixed it on Adreno.

Deep Links With Authentication in React Navigation

This article walks through how to make deep links work when the screen is behind authentication, so the user automatically navigates to the correct deep link after logging in. It discusses manual approaches to implement this, the downsides of these approaches, and shows how React Navigation 7 introduces a built-in option with UNSTABLE_routeNamesChangeBehavior that makes it easier to handle.

Integrating Swift Package Manager With React Native Libraries

React Native has relied on CocoaPods for iOS dependency management, but Swift Package Manager has become the preferred option for modern Swift development due to its performance and tight Xcode integration. Since React Native 0.75, the spm_dependency helper lets libraries declare SPM packages directly in their podspec files, enabling support for third-party Swift packages distributed only through SPM. This article explains how the integration works, how to adopt it for both remote and local packages, and what to expect until official support ships.
