Expo Phaser Toolkit
You can now use the Phaser code editor on Expo using the Expo Phaser toolkit. You can use it for developing 2D games on iOS and Android.
This toolkit helps you maintain customized versions of Phaser for a smoother integration with the open source toolchain. It also maintains global instances of several libraries including Pixi.js and P2.js. You can also import other custom libraries when needed.
The Expo Phaser comes with sample games and documents to help you get started. Learn more here.
