## What is Expo & React Native components?

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.
