Build a Full Stack AI Image Generator App in React Native, NodeJS| React Native Project Setup 2

Introduction

Welcome back to the course! In our previous video, we introduced the app we are going to build together. One essential aspect I forgot to mention is the Details Screen that appears when you click on an image. This session focuses on setting up our React Native project, a critical first step in our development process.

Project Flow Overview

Before diving into the project setup, let me outline our planned workflow:

UI Design: We will first focus on the user interface, coding on the reactive side.
Server Setup: After the UI is complete, we’ll build and deploy a server.
API Integration: Following that, we will integrate the API using Axios and implement React Query in React Native.

If you are new to React Native, don’t worry—our tutorial starts from the very basics, ensuring you can grasp the concepts easily.

Setting Up the React Native CLI Project

Now, let's discuss how to set up a React Native CLI project. We will use the React Native CLI to create a new project.

Open your Browser: Start by opening your browser to access the React Native website.
Getting Started: Click on the first article that appears in the search results and select "Get Started."
React Native CLI Command: Look for the command npx react-native init YourProjectName and copy it.

Here, you can name your project anything you like. For this tutorial, let’s name it GenerateImageAI.
Creating the Project: Navigate to the directory where you want to create your project using your terminal:
```
mkdir course
cd course
npx react-native init GenerateImageAI
```
Navigating to Your Project: Once the project is created, change into the project directory:
```
cd GenerateImageAI
```
Open the Project in Your IDE: Use Visual Studio Code or any favored IDE to open the project:
```
code .
```
Running the Project: To run your new React Native project, execute the following command in the terminal:
```
npx react-native run-android
```
This command may take a bit of time, depending on your internet speed and computer specifications.

Resolving Possible Errors

If you encounter an error message like "could not move temporary workspace", don't panic! Sometimes, simply re-running the command will resolve the issue. Alternatively, you can search for the error message online for specific fixes.

Manual Emulator Start: If your emulator fails to start automatically, you may need to manually open it, then run the installation command again.

Once the app is installed successfully, you can test hot reloading by pressing R in the terminal to refresh the application instantly.

In our next session, we will set up React Native Vector Icons and explore more features as outlined in our Figma design. If you encounter any problems during the setup, feel free to reach out.
