GPUDevice: uncapturederror event
Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.
The uncapturederror
event of the GPUDevice
interface is fired when an error is thrown that has not been observed by a GPU error scope, to provide a way to report unexpected errors.
Known error cases should be handled using pushErrorScope()
and popErrorScope()
.
Syntax
Use the event name in methods like addEventListener()
, or set an event handler property.
js
addEventListener("uncapturederror", (event) => {});
onuncapturederror = (event) => {};
Event type
An GPUUncapturedErrorEvent
. Inherits from Event
.
Examples
You could use something like the following as a global mechanism to pick up any errors that aren't handled by error scopes and capture them.
js
device.addEventListener("uncapturederror", (event) => {
// Re-surface the error.
console.error("A WebGPU error was not captured:", event.error);
reportErrorToServer({
type: event.error.constructor.name,
message: event.error.message,
});
});
