Question 1

How do I set up React Native WebGPU with Expo?

Accepted Answer

Use the Expo template with 'npx create-expo-app@latest -e with-webgpu' for a quick start on iOS, Android, and Web, but note that native dependencies like Dawn still need handling for full functionality.

Question 2

React Native WebGPU vs Expo GL: which is better for 3D graphics?

Accepted Answer

React Native WebGPU offers low-level WebGPU access for custom shaders and high-performance compute, while Expo GL is higher-level and easier for basic 3D but less flexible and may not support advanced GPU features.

Question 3

How to load external images as textures in React Native WebGPU?

Accepted Answer

Use the provided createImageBitmap function with copyExternalImageToTexture, as shown in the README's 'External Textures' section, but note it requires fetching assets and managing blobs, adding complexity.

Question 4

What platforms does React Native WebGPU support?

Accepted Answer

It supports iOS, Android, Web, visionOS, and macOS with prebuilt binaries, but check for specific version requirements like React Native 0.81+ and be prepared for platform-specific bugs, such as iOS simulator Metal validation issues.

Question 5

How to run WebGPU code on the UI thread with Reanimated?

Accepted Answer

Install react-native-reanimated and react-native-worklets, then pass WebGPU objects like GPUDevice to worklets using runOnUI, as detailed in the 'Reanimated Integration' section, but this adds dependency management overhead.

Question 6

Is React Native WebGPU stable for production use?

Accepted Answer

It's built on experimental tech like Dawn and WebGPU, so while functional, it may have breaking changes and require careful testing, especially given the manual setup and platform quirks outlined in the README.
