I created a rust-wasm module and use workerize-loader to load it:
export const getQRCode = async (
arg: string,
width: number,
height: number
) => {
const { qrcode } = await import('uranus-qrcode');
return qrcode(arg, width, height);
};
and then I use the worker as such:
// @ts-ignore
// eslint-disable-next-line import/no-webpack-loader-syntax
import qrCodeWorker from 'workerize-loader!workers/qrCodeWorker';
...
const workerizeQRLoader = async () => {
try {
const instance = qrCodeWorker();
const qr = await instance.getQRCode(href, 150, 150);
setQRCode({
__html: qr
});
} catch (e) {
console.warn(e);
}
};
...
useEffect(() => {
workerizeQRLoader();
// qrLoader();
// eslint-disable-next-line react-hooks/exhaustive-deps
}, []);
...
The above works in dev mode, but after compiling it says:
TypeError: a.getQRCode is not a function

If I import the rust-wasm module directly into the main thread it works:
...
const qrLoader = async () => {
const { qrcode: render } = await import('uranus-qrcode');
const qr = await render(href, 150, 150);
setQRCode({
__html: qr
});
};
useEffect(() => {
// workerizeQRLoader();
qrLoader();
// eslint-disable-next-line react-hooks/exhaustive-deps
}, []);
