How to Use Liquid Glass in React Native

Liquid Glass is Apple’s next-generation translucent material in iOS 26, designed to highlight content while keeping interfaces clear and dynamic. In this guide, we show how to use it in React Native, from best practices around readability and performance to hands-on examples with single and grouped glass elements. Whether you’re experimenting with Apple’s latest design language or adding polish to production apps, this article walks you through the essentials.

How to Add Custom JSI Bindings in Your TurboModule (and Why You Might Need Them)

TurboModules provide a type-safe way to write native code in React Native. JSI sits underneath as a lower-level API, enabling direct interaction with the JavaScript runtime. This article explains how to safely inject custom bindings with an ArrayBuffer example.

On-Device Text To Speech on Apple Devices with AI SDK

We’ve added on-device speech synthesis to our Apple provider for the AI SDK, completing the feature set alongside generation, embeddings, and transcription. This integration with AVSpeechSynthesizer brings fast, private, and offline text-to-speech to React Native, with support for multiple voices, languages, and even Personal Voice on iOS 17+.

Secure Communication Between Isolated React Native Instances

The latest release of react-native-sandbox adds support for direct, secure communication between sandboxed React Native instances. Instead of routing messages through the host app, sandboxes can now talk to each other directly using a model familiar from the web: the postMessage API with origin-based access control.

Visualizing Open Source Licenses to Analyze Compliance and Reduce Legal Risk

Tracking open-source licenses isn’t just about reading package.json. Hidden obligations often live deep in transitive dependencies. license-kit visualize offers a clear, interactive map of your project’s dependency graph, complete with license details, statistics, and AI-generated summaries. Whether you’re avoiding restrictive terms or understanding how packages enter your stack, this tool gives you the visibility you need to manage licenses with confidence.

On-Device Speech Transcription in React Native with Apple SpeechAnalyzer

This post introduces speech transcription support in React Native AI, implemented using Apple’s SpeechAnalyzer and SpeechTranscriber APIs available in iOS 26. It explains how to use the AI SDK’s transcribe function to pass audio buffers, how modular analysis is configured through the SpeechAnalyzer class, and how system-level asset management ensures models are handled outside the app bundle.

How Node-API Works in React Native: A Deep Dive

In this deep dive, we explain how Node-API is brought to React Native—from discovering and bundling native addons to loading them at runtime. We also walk through the design of the host system and tools that make it all work.

Running Multiple Instances of React Native in Sandbox

While micro-frontend architectures have revolutionized feature delivery in React Native, they don't solve the core problem of runtime isolation. This creates security and stability risks, especially when integrating code from third-party developers. This article introduces react-native-sandbox, a powerful library that allows you to run multiple, fully isolated React Native instances inside a single host application. We explore how this sandboxing approach provides true crash containment, configurable security permissions for native modules, and enables independent team delivery, paving the way for truly modular and secure super apps.
