我试过了:
// Worker.ts
// @ts-ignore
// eslint-disable-next-line no-restricted-globals
const ctx: Worker = self as any;
// Post data to parent thread
// ctx.postMessage({ foo: "foo" });
// Respond to message from parent thread
ctx.addEventListener('message', async ({ data }) => {
const {
href,
width,
height
} = data;
const { qrcode } = await import('uranus-qrcode');
const qr = qrcode(href, width, height);
ctx.postMessage({ href, qr });
});
其中uranus-qrcode
是我创建的 Rust-Wasm 模块。我使用 wasm-loader 加载它,当我将它加载到主线程时它可以工作,但是当我使用 worker-loader 尝试它时它说:
