freeCodeCamp published a new 3-hour course walking developers through building and shipping CodexGram, an Instagram-style social app, from idea to the App Store.
The course's core thesis: AI tools don't remove the engineering work — planning, backend, testing, and App Store review compliance all still matter, going well beyond superficial "vibe coding."
Key stack and features:
- Expo (React Native) + TypeScript, NativeWind styling, Expo's liquid-glass Native Tabs
- Clerk for Google/Apple sign-in
- Convex for reactive database, image uploads, and live updates
- Social feed: photo posts, likes, threaded comments, 24-hour stories
- Real-time 1-on-1 DMs and an explore grid
- Sentry for crash tracking and structured logging
- Legal/marketing site deployed to Cloudflare Pages
A useful reference for anyone shipping a full mobile product solo with AI coding tools.
