Part 1:The Ultimate React Native Installation Guide: Prerequisites and Setup
Welcome to the React Native series! In this guide, we’ll discuss prerequisites and the installation process for both Mac and Windows systems.
**1. Prerequisites:**
The essential prerequisite for starting with React Native is a basic understanding of JavaScript. You might have come across numerous videos about JavaScript loops and functions, but it’s crucial to grasp the basics rather than diving deep without application. The most effective way to truly understand any programming language is by building with it. This hands-on approach is the one we will adopt throughout this course.
**2. React Native and TypeScript:**
React Native now supports TypeScript by default. While we won’t delve deep into it initially, once you’re more comfortable, we will introduce its nuances.
**3. Learning Approach:**
From my experience creating over 100 courses, the most effective learning method is building first and then understanding the underlying concepts. We will be crafting various projects, and with each one, we’ll explore a new aspect of React Native.
**4. Installation:**
The installation process is where many get intimidated. Contrary to popular belief, you don’t need high-end devices for React Native. A basic computer that can run VS Code is sufficient. The primary tools are Android Studio and Xcode, but the secret is that you don’t need to *use* Android Studio, you just need to *install* it. I’ll be using my older OnePlus 7 Android device for demonstrations, and with just that and VS Code, we’ll build apps compatible with both Android and iOS.
**Steps:**
- Start with installing Node.js. It’s essential for running JavaScript.
- React Native allows for cross-platform app development using JavaScript, which is then transferred to Android and iOS.
- For Windows users: Install VS Code, Java (Open JDK), and Android Studio. You can use a package manager like Chocolatey for easier installations.
- For Mac users: Install VS Code, Java, Android Studio, and optionally Xcode if you want to test on iOS.
**Key Tools and Notes:**
- Android Debug Bridge (ADB) is a vital tool we’ll use. It comes by default with Android Studio.
- No need to configure or create any virtual devices or simulators in Android Studio. The primary reason for its installation is to get the SDK platform tools.

**Conclusion:**
Mobile app development with React Native is straightforward and doesn’t require excessive resources. This guide should provide clarity and boost your confidence to dive into the world of React Native. Stay tuned for more in-depth tutorials, and I’ll see you in the next video!
