It covers Clerk authentication, a Convex real-time backend with image uploads, a social feed with stories and comments, direct messaging, Sentry observability, and deploying a legal/marketing landing page to Cloudflare Pages, culminating in App Store submission. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What tech stack is used to build a full-stack Instagram-style mobile app with Expo and React Native? A production-ready social app like CodexGram combines Expo (React Native) and TypeScript for the client, styled with NativeWind, Clerk for Google and Apple sign-in, Convex as a reactive real-time backend for data and image storage, Sentry for crash tracking and logging, and Cloudflare Pages for the marketing and legal site. _Developers piecing together a mobile stack can follow similar full-stack app breakdowns on daily.dev._ ### How can I implement 24-hour disappearing stories with tap-to-advance in a React Native app? Stories with 24-hour expiry, tap-to-advance, and hold-to-pause interactions can be implemented as part of a social feed built on Expo (React Native) with a reactive backend like Convex handling live updates, alongside photo uploads, captions, and like/unlike toggles for the broader feed functionality. _Developers building social-style feed features can find similar implementation walkthroughs through 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 --- Tags: [#mobile](https://daily.dev/tags/mobile), [#typescript](https://daily.dev/tags/typescript), [#react-native](https://daily.dev/tags/react-native), [#convex](https://daily.dev/tags/convex) [View this post on daily.dev](https://daily.dev/posts/build-and-publish-a-full-stack-mobile-app-with-ai-xumtefxsq) ```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":"Build and Publish a Full-Stack Mobile App with AI","url":"https://daily.dev/posts/build-and-publish-a-full-stack-mobile-app-with-ai-xumtefxsq","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/build-and-publish-a-full-stack-mobile-app-with-ai-xumtefxsq"},"datePublished":"2026-10-01T22:28:14.365Z","dateModified":"2026-10-01T22:28:32.811Z","description":"A long-form freeCodeCamp YouTube tutorial walks through building and publishing CodexGram, an Instagram-style social app, using Expo (React Native) and...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/80858a832adbf24c168dca04a2d36fa9?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/80858a832adbf24c168dca04a2d36fa9?_a=AQAEuop","isAccessibleForFree":true,"articleSection":"freeCodeCamp","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"freeCodeCamp","logo":"https://media.daily.dev/image/upload/t_logo,f_auto/v1628412854/logos/freecodecamp","url":"https://daily.dev/sources/freecodecamp"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/build-and-publish-a-full-stack-mobile-app-with-ai-xumtefxsq","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":7},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"mobile,typescript,react-native,convex","timeRequired":"PT2M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"freeCodeCamp","item":"https://daily.dev/sources/freecodecamp"},{"@type":"ListItem","position":3,"name":"Build and Publish a Full-Stack Mobile App with AI"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/build-and-publish-a-full-stack-mobile-app-with-ai-xumtefxsq#faq","mainEntity":[{"@type":"Question","name":"What tech stack is used to build a full-stack Instagram-style mobile app with Expo and React Native?","acceptedAnswer":{"@type":"Answer","text":"A production-ready social app like CodexGram combines Expo (React Native) and TypeScript for the client, styled with NativeWind, Clerk for Google and Apple sign-in, Convex as a reactive real-time backend for data and image storage, Sentry for crash tracking and logging, and Cloudflare Pages for the marketing and legal site.
