React Native Components & APIs is two things in one app: a catalog of runnable library demos, and a full React Native learning library. All of it works offline. 50 RUNNABLE LIBRARY EXPLORERS Open a library, run its demos, and read the exact source that produced the screen in front of you: • Frameworks & platform — React Native core (RNTester), Expo Components, TanStack Query, TinyBase, Zustand, Legend-State • UI kits & design systems — React Native Paper, Tamagui, HeroUI Native, Gluestack UI, NativeWindUI, Enriched Markdown, Enriched HTML, Bottom Sheet • Graphics & motion — Skia, Reanimated, Lottie, Victory Native XL, Gifted Charts, Mesh Gradient, Glass Effect • Lists, forms & data — FlashList, LegendList, React Hook Form, Formik, SQLite • Native integrations — VisionCamera, Maps, Notifee, Audio API, Gesture Handler, Haptics, Live Photo, Notifications, Action Sheet READ THE SOURCE, NOT A DOC SITE Every demo ships with a built-in source viewer. Tap the code icon on any screen to read the actual TypeScript behind it, switch between files, and copy what you need into your own project. The version shown next to each library is the version the app is genuinely built against. A CURRICULUM, NOT A LINK DUMP 520 lessons across 22 tracks: JavaScript and TypeScript foundations, React 19, the New Architecture, navigation, performance, native modules, testing, security, release engineering, architecture patterns, and building with AI. Every code sample is compiled against the installed React Native 0.86, React 19.2 and Expo 57 — if a sample would not build, the app would not have shipped. INTERVIEW PREPARATION THAT GOES DEEPER THAN A LIST 666 questions with short answers, full explanations, and 1,317 follow-up questions — the ones an interviewer actually asks next, graded across beginner, intermediate and advanced. PRACTICE, NOT JUST READING • Spaced repetition across 430 flashcards and your interview questions, on one schedule — rate how well you recalled it and the card comes back when it should • 36 quizzes, 540 questions, with an explanation behind every answer • 17 cheat sheets, 5 release-day checklists, 11 decision guides and 40 code challenges • A 337-term glossary that appears inline as you read — tap any term without losing your place • Search across lessons, terms, questions, cheat sheets, checklists and quizzes at once EVERYTHING IS OFFLINE The whole library ships inside the app. No account, no sign-in, no network required — on a plane, on the underground, or in a waiting room before the interview. ONE PURCHASE, NO SUBSCRIPTION Every library demo and its source code is free. The learning library opens the first share of every section for free, and a single one-time purchase — pick whatever tier feels fair, from a cup of coffee upward — unlocks every lesson and interview question for good and removes ads. No subscription, nothing expires. WHO IT IS FOR • React Native developers evaluating a library before adding a dependency • Engineers preparing for a mobile interview • Anyone learning React Native who would rather run code than read about it Feedback is genuinely welcome — there is a Send Feedback link in the More tab.
