The tech stack includes Clerk for authentication (with OAuth providers like Google, Apple, and GitHub), Neon PostgreSQL with Drizzle ORM for the database, NativeWind (Tailwind CSS for React Native) for styling, and Zustand for state management. The course walks through project setup, file-based routing with Expo Router, React vs React Native component differences, NativeWind configuration, Clerk integration with prebuilt native UI components, and development builds. All tools used are free to get started with. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### How do I set up Clerk authentication with custom pre-built native UI components in an Expo React Native app? Clerk offers pre-built native components like OAuthView under a beta feature requiring Expo SDK 53 or later and a development build rather than Expo Go. After installing @clerk/clerk-expo and expo-secure-store, adding the clerk-expo plugin to app.json, and wrapping the app in ClerkProvider, the OAuthView component can replace hundreds of lines of custom sign-in UI with about 15 lines supporting sign-in, sign-up, or both modes. _Developers wiring up Clerk auth in Expo apps can compare setup approaches and gotchas surfaced on daily.dev._ ### How can I make a FlatList in React Native more performant than mapping over an array with .map()? FlatList only renders the items currently visible on screen plus a small buffer, then renders more as the user scrolls, whereas array.map() renders every item immediately regardless of visibility, wasting memory with large lists. FlatList supports a data prop, keyExtractor, renderItem, plus listHeaderComponent, listFooterComponent, and listEmptyComponent for building a full scrollable screen with header and footer sections. _Anyone optimizing list rendering in React Native can dig into FlatList patterns and alternatives shared on daily.dev._ ### What is the free tier limit for Clerk authentication in a React Native or Expo app? Clerk's free plan supports up to 50,000 monthly active users at no cost, with only three social OAuth providers allowed on the free tier versus more on paid plans. The Pro plan costs around $20 a month. Given the high free-tier user cap, Clerk is presented as a practical choice for both beginners and production apps built with Expo. _Developers choosing an auth provider for a mobile app can weigh Clerk's pricing tiers alongside other options on daily.dev._ ## Similar posts on daily.dev - [Master Full-Stack Mobile Development with React Native](https://daily.dev/posts/master-full-stack-mobile-development-with-react-native-acg5lvuzs) · freeCodeCamp · 8 upvotes · 0 comments - [From React Web to Native in One Week](https://daily.dev/posts/from-react-web-to-native-in-one-week-zxr4npbt3) · Expo Blog · 62 upvotes · 3 comments --- Tags: [#react-native](https://daily.dev/tags/react-native), [#drizzle](https://daily.dev/tags/drizzle) [View this post on daily.dev](https://daily.dev/posts/react-native-full-stack-course-clerk-postgres-nativewind-1jkyl8mzq) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"React Native Full Stack Course – Clerk, Postgres, NativeWind","url":"https://daily.dev/posts/react-native-full-stack-course-clerk-postgres-nativewind-1jkyl8mzq","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/react-native-full-stack-course-clerk-postgres-nativewind-1jkyl8mzq"},"datePublished":"2026-07-13T12:08:43.674Z","dateModified":"2026-09-14T06:24:28.466Z","description":"A beginner-friendly full stack React Native course covering how to build a cross-platform grocery list app from scratch using Expo.
