React Native App Development
You already know React. Learn the part that ships to the App Store — native performance, platform behaviour, and releases you can push the same day. Most React Native tutorials still explain the Bridge; it doesn't exist any more. This course teaches the framework as it actually ships. Built for fresh IT graduates and working developers alike.
The New Architecture transition is over, and most course content hasn't noticed. The old Bridge — the asynchronous, JSON-serialising layer between JavaScript and native that gave React Native its performance reputation — has been removed from current releases: the modern JavaScript interface, renderer and typed native modules are no longer an opt-in migration path, they are the only architecture, with the remaining legacy code being stripped release by release. Recent releases have gone further — a new-generation JavaScript engine as the default, and precompiled iOS binaries to cut build times. Everything you debug later depends on understanding this model, so it's Module 1.
This course's centre of gravity is leveraging the React you already know, and shipping velocity. The managed framework path is now the recommended default, not a beginner shortcut: development builds give full native access, and the hosted build, submit and over-the-air update services are how most teams release repeatedly without touching Xcode or Android Studio for most work — with the bare-workflow escape hatch taught for when it's genuinely warranted. Over-the-air updates are treated as a real product capability — pushing fixes without a store review cycle, within each store's policy limits — and library compatibility auditing is taught as a real skill, because a meaningful minority of packages still lag the current architecture, and assessing a dependency before adopting it is exactly the judgment that separates a professional from a tutorial follower.
If you can build a React component and manage state, you already know most of this course's language. What you don't know is the mobile part — and that's what this is. React is a prerequisite here, not a competitor: the sequence is our React.js course first if you need it, then this. We don't re-teach JSX, hooks or component basics. The program runs 9 weeks (~65 hours), live and build-along, closing with a capstone submitted as a store-ready build — and because versions move out of support quickly in this ecosystem, upgrade planning is taught as a routine engineering task, not an occasional project.
React Native or Flutter?
- React Native (this course) — reuses your existing JavaScript, TypeScript and React skills and the npm ecosystem, renders using actual platform components for native feel by default, and has the largest talent pool of the cross-platform options. Choose it when your team already knows React, when you want platform-native feel by default, or when you're sharing code and people with a web product.
- Flutter — owns its rendering layer: pixel-perfect consistency across platforms and the broadest single-codebase reach, at the cost of learning Dart. We sell that course too, and the comparison there says the same things this one does.
- Kotlin Multiplatform — shares business logic with native UI per platform, for teams where native UX is non-negotiable. No disparagement anywhere in this comparison: a one-sided pitch would cost both pages your trust.
Why Learn React Native When AI Writes Screens?
Same honest answer as the rest of this section: AI produces React Native screens fluently and gets mobile-specific things wrong — list performance and re-render scope, animations that run on the JavaScript thread instead of the UI thread, native module compatibility, permissions and platform behaviour, and anything touching the build. Those surface as jank, crashes and store rejections rather than compile errors. The value is architecture, performance judgment and shipping through app review. You'll use AI tooling as an accelerator you review, and you'll learn the failure patterns generated mobile code repeats — so you ship its speed without shipping its mistakes.

- Curriculum: 9 modules, from the modern architecture to release, operations and capstone
- Portfolio: 8 production-style builds plus a store-ready capstone
- Curriculum reviewed: July 2026 — this ecosystem moves fast and its tutorials lag it; this syllabus is checked against official documentation
Course Highlights
- Every module leads with what you build and ship, not what you "learn about"
- The New Architecture taught as the only architecture — no Bridge folklore
- The managed workflow as the professional default — with the bare escape hatch taught honestly
- Over-the-air updates as a product capability, inside store policy limits
- Animations on the UI thread with worklets — not JS-driven approximations
- Library auditing as a taught skill — assess a dependency before you depend on it
- Upgrade planning as routine engineering — versions leave support quickly here
- Store submission taught properly — the review pitfalls that cause rejections
- AI tooling as an accelerator you review, never a substitute for understanding
Hands-on Projects & Portfolio
File-based navigation, authentication, deep linking and a typed API layer.
Local persistence, background sync and conflict resolution.

Evaluate real dependencies for architecture compatibility and maintenance risk, and justify the decisions.
End-to-end tests running on device in CI.
Ship a fix to users without a store submission.
Production app, tested, profiled and submitted as a store-ready build.

Career Outcomes
React Native's practical advantage is skill and team reuse — a React web developer becomes a mobile developer in weeks rather than months, and one team can maintain web and mobile products sharing language, tooling and often code. That makes it common in startups, product companies and organisations that already have a React web codebase — and the combination of web plus mobile capability in one developer is unusually marketable. This course targets:
- React Native Developer
- Mobile App Developer
- Cross-Platform Developer
- Product Engineer
- Full-Stack Developer (web + mobile)
- Freelance or agency app developer
- Technical founder shipping a mobile product
Who This Course Is For
- React and web developers moving into mobile — the primary audience: pair this with our React.js Development course if you need the prerequisite first
- Final-year students and fresh IT graduates targeting mobile or product engineering roles
- Full-stack developers who need to ship a mobile front end for their own product
- Teams maintaining older React Native apps still on the legacy architecture — the migration is now mandatory rather than optional, and the upgrade workflow is taught here
- Native Android or iOS developers adding cross-platform reach
- Freelancers and founders shipping to both stores with limited resources
Material Includes
- Class recordings
- App starter repos & typed API templates
