Electrobun WebGPU FAQs

Question 1

What configuration is needed for WebGPU to work?

Accepted Answer

You must set 'bundleWGPU: true' in your electrobun.config.ts for Mac, Windows, and Linux to ensure the native WGPU library is included in your application bundle.

Question 2

Why do I need to use DataView for GPU buffers?

Accepted Answer

GPU structs must be manually serialized. DataView is used to write data (like floats) into ArrayBuffers with explicit little-endian ordering to ensure compatibility across different CPU architectures.

Question 3

What is the KEEPALIVE pattern in Electrobun WebGPU?

Accepted Answer

The KEEPALIVE pattern is a critical technique where GPU objects are stored in a persistent array to prevent Bun's garbage collector from reclaiming FFI pointers, which would cause application crashes or segfaults.

Question 4

Does Electrobun WebGPU render inside the browser webview?

Accepted Answer

No, Electrobun GPU windows bypass the webview entirely and render directly to a native surface using WGPU for maximum performance.

Question 5

What happens if I forget the KEEPALIVE array?

Accepted Answer

Without holding references to your GPU objects, Bun may garbage collect them while the GPU is still using them, leading to immediate segmentation faults or silent data corruption.
