About this app

React Native Bible is a free, offline reference app for intermediate and advanced React Native developers.
It covers the parts of React Native that are easy to use but hard to fully understand — the New Architecture, JSI, Fabric, TurboModules, performance optimization, accessibility, native debugging, and the full path to publishing on Android and iOS.
What's inside
Learn — in-depth topics organized by subject: layout, performance, under the hood, debugging, accessibility, Android, iOS, and publishing. Each topic is written to explain not just what an API does, but why it works that way.
Components — a hands-on reference for React Native's core components, with live, interactive previews you can actually press, type into, and scroll — not just static prop tables.
Quizzes — test what you've learned with multiple-choice questions built directly into each Learn section, with explanations for both the correct answer and the most common misconceptions.
Built to respect your time and your data
No account. No login. No backend. No analytics or tracking of any kind. Every piece of content ships inside the app and works completely offline — on a plane, on the subway, anywhere.
Available in English, Portuguese, and Spanish.
React Native Bible is open source. Contributions, corrections, and suggestions are welcome on GitHub.
