Introduction
Are you familiar with Pixi.js, the popular open-source JavaScript library for creating interactive, real-time graphics and games? Have you ever wondered how to integrate your Pixi.js project into a React Native screen using Expo Go? Well, wonder no more! In this article, we’ll take you through a step-by-step guide on how to do just that.
Prerequisites
Before we dive in, make sure you have the following installed on your machine:
- Expo CLI (version 4 or higher)
- React Native (version 0.64 or higher)
- Pixi.js (version 6 or higher)
Creating a New React Native Project with Expo
Let’s start by creating a new React Native project using Expo. Open your terminal and run the following command:
expo init my-pixi-projectFollow the prompts to choose a template, and select the “blank” template. Once the project is created, navigate to the project directory:
cd my-pixi-projectInstalling Pixi.js
Next, we need to install Pixi.js in our project. Run the following command:
npm install pixi.jsCreating a New Pixi.js Project
Now, let’s create a new Pixi.js project. Create a new folder called “pixi” inside your project directory, and create a new file called “index.js” inside the “pixi” folder:
mkdir pixi
cd pixi
touch index.jsIn “index.js”, add the following code to create a basic Pixi.js scene:
import * as PIXI from 'pixi.js';
const app = new PIXI.Application({
width: 800,
height: 600,
backgroundColor: 0x000000,
});
const container = new PIXI.Container();
app.stage.addChild(container);
const graphics = new PIXI.Graphics();
graphics.beginFill(0xFF0000);
graphics.drawRect(0, 0, 100, 100);
graphics.endFill();
container.addChild(graphics);
app.ticker.add(() => {
// Update your Pixi.js scene here
});
Integrating Pixi.js with React Native
Now that we have our Pixi.js project set up, let’s integrate it with our React Native project. Create a new file called “PixiScreen.js” in the root of your project directory:
touch PixiScreen.jsIn “PixiScreen.js”, add the following code to create a new React Native screen that will render our Pixi.js scene:
import React, { useState, useEffect } from 'expo';
import { View, WebView } from 'react-native';
import Pixi from './pixi/index';
const PixiScreen = () => {
const [html, setHtml] = useState('');
useEffect(() => {
const pixiHtml = `
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
</head>
<body>
${Pixi}
</body>
</html>
`;
setHtml(pixiHtml);
}, []);
return (
<View style={{ flex: 1 }}>
<WebView
source={{ html: html }}
style={{ flex: 1 }}
/>
</View>
);
};
export default PixiScreen;
Configuring Expo Go
Finally, we need to configure Expo Go to run our React Native project. Open the “app.json” file in the root of your project directory and add the following configuration:
{
"expo": {
"name": "my-pixi-project",
"slug": "my-pixi-project",
"version": "1.0.0",
"orientation": "portrait",
"icon": "./assets/icon.png",
"extra": {
"eas": {
"projectId": "your-project-id"
}
}
}
}
Replace “your-project-id” with your actual Expo project ID.
Running the Project
Now that we’ve set up our project, let’s run it using Expo Go. Open the Expo Go app on your mobile device, and scan the QR code displayed in your terminal:
npx expo startOnce the project is loaded, you should see your Pixi.js scene rendered in a React Native screen!
Troubleshooting
If you encounter any issues while running your project, here are some common troubleshooting steps:
- Check the Expo Go console logs for any errors.
- Verify that you have the correct versions of Node.js, Expo CLI, and React Native installed.
- Make sure you have installed Pixi.js correctly and imported it correctly in your “PixiScreen.js” file.
- Check the “app.json” file for any typos or incorrect configurations.
Conclusion
And that’s it! You’ve successfully integrated your Pixi.js project with a React Native screen using Expo Go. You can now take advantage of the powerful features of Pixi.js and React Native to create stunning, interactive graphics and games for mobile devices.
Remember to explore the official documentation of Pixi.js and React Native for more advanced features and customization options.

Frequently Asked Questions
Get started with Pixi.js and Expo Go, and overcome any hurdles with our comprehensive FAQs!
Can I run Pixi.js in a React Native project using Expo Go?
Yes, you can! Pixi.js is a JavaScript library that can be used with React Native, and Expo Go provides a convenient way to run your project on a physical device. You’ll need to install the Pixi.js library and configure it to work with your React Native project.
How do I integrate Pixi.js into my React Native project using Expo Go?
To integrate Pixi.js, you’ll need to install the library using npm or yarn, then import it into your React Native component. You’ll also need to configure the Pixi.js renderer to work with your project’s layout and styling. Expo Go provides a WebView component that can be used to render Pixi.js content.
Do I need to use a specific version of Pixi.js for Expo Go?
While Pixi.js is compatible with Expo Go, it’s recommended to use a version that’s compatible with React Native. Currently, Pixi.js version 5.x is the recommended version for use with Expo Go.
How do I handle touch and gesture events in my Pixi.js project using Expo Go?
To handle touch and gesture events, you’ll need to use the Pixi.js event system, which provides a way to handle touch events, clicks, and gestures. You’ll also need to use Expo Go’s built-in gesture handling system to receive native touch events and forward them to your Pixi.js application.
Can I use Pixi.js plugins and extensions with Expo Go?
Yes, you can use Pixi.js plugins and extensions with Expo Go, but you may need to modify them to work with the React Native environment. Some plugins may require additional configuration or tweaking to work correctly with Expo Go.
