Build a fully functional cross-platform mobile app using Expo and React Native. We'll cover navigation, state management, API calls, and how to publish to the App Store and Google Play.
What You'll Build
A news reader app that fetches live articles from a public API, displays them in a polished list, and allows bookmarking with local persistence.
Bootstrap with Expo
Create a new Expo app with TypeScript support, configure ESLint and Prettier, and run it on a simulator or physical device.
File-Based Routing with Expo Router
Set up tab navigation and stack navigation using the file-based routing system — no configuration required.
Fetch Data with React Query
Connect to a REST API, handle loading and error states, and implement pull-to-refresh and pagination.
Local Storage with MMKV
Persist bookmarks locally using MMKV, the fastest key-value store for React Native.
Build & Submit
Use EAS Build to create production binaries and EAS Submit to publish to both app stores.
