React Native Essentials – Build Mobile Apps like a Pro | Udemy

Welcome!

If you already know JavaScript and want to build real mobile apps for iOS and Android—without the pain of native setup—then React Native with Expo is your best friend.

Expo is a framework and platform built around React Native that simplifies everything—from development to testing and deployment. No need to mess with Xcode or Android Studio just to get started.

And with the Expo Go app, you can instantly preview your apps on your real device just by scanning a QR code. No build process, no waiting—just code and see it live. It’s the perfect way to prototype, test, and iterate faster.

In this course, we’re leveraging the full power of Expo along with TypeScript to build professional, scalable apps. And now, let me walk you through what you’ll learn in each section.

TypeScript Basics
We begin with the essentials—TypeScript. You’ll learn how to write safer, smarter, and more maintainable code right from the start.

Basic Components and Layouts
You’ll get comfortable with React Native UI components like Text, Image, Pressable, FlatList, and Flexbox—learning how to build beautiful layouts that adapt to any screen.

State Management + BMI Calculator
We introduce the useState hook through a fun and functional BMI Calculator App—your first React Native project!

Dice Game + Expo Router
Build a fully interactive Dice Game using states and logic. Here, we also dive into expo-router to simplify navigation with a modern, file-based approach.

Weather App with Context API
This section is packed! You’ll build a Weather App with current and forecast data, temperature conversion, city search, and device location detection—all while learning how to share state using the Context API.

Smart Contact App with Gemini + Firebase
Here, we bring in AI and backend magic. Build a Smart Contact App that uses Gemini API to scan a business card and extract contact details. You’ll also implement Firebase Authentication, Firestore, and Storage for full cloud integration.

Reducer Pattern + Context

To wrap up, we dive deeper into state logic with the Reducer pattern and combine it with Context—giving you the tools to manage complex app states with ease.

By the end of this course, you’ll be ready to build and ship real-world apps like a pro.
So take it one step at a time, practice consistently, and don’t hesitate to reach out in the Q&A if you need help.

Once again—welcome aboard, and let’s start building amazing mobile apps together!
