WebGPU: GPUCanvasContext getConfiguration()

Functionality added to the WebGPU spec after its first shipment in a browser. Once GPUCanvasContext configure() has been called with a configuration dictionary, the GPUCanvasContext getConfiguration() method lets developers check the canvas context configuration. It includes GPU device, format, usage, viewFormats, colorSpace, toneMapping, and alphaMode m

concepts

  1. GPUCanvasContext.getConfiguration

    GPUCanvasContext.getConfiguration() returns the active context configuration. Lets libraries inspect what the host set up.

  2. Host + overlay handoff

    Simulate a 3D library configuring the canvas and a custom overlay pass reading the active config back.

  3. Configure → getConfiguration round-trip

    Pick every config field, call configure(), read back. Confirm every value comes back exactly.

  4. Library handshake log

    Host configures, overlay reads via getConfiguration(). Compatibility verdict and log of the handshake.

why it shipped
