Debug Qt WebAssembly applications

To debug a Qt WebAssembly application with Chrome:

1. Open a launch.json file. For more information, see Debug Qt applications.
2. Select Add Configuration, and then select the Qt: Debug Qt WASM with Chrome debug configuration.

The Qt: WASM Start task in the preLaunchTask section checks the required dependencies and prompts you to install them if necessary.

Debug multi-thread applications

For multi-thread Qt WebAssembly applications, set the following configuration in settings.json:

"livePreview.httpHeaders": {
    "Cross-Origin-Embedder-Policy": "require-corp",
    "Cross-Origin-Opener-Policy": "same-origin",
    "Accept-Ranges": "bytes"
}

Otherwise, you might see the SharedArrayBuffer is not defined error.
