worker-loader 无法在 React 项目中使用 wasm-loader 和 typescript
worker-loader cannot work with wasm-loader and typescript in react project
我试过:
// 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 来加载它,当我将它加载到主线程时它可以工作,但是当我用 worker-loader 尝试它时它说:
Uncaught (in promise) TypeError: Cannot read property './modules/uranus_qrcode/uranus_qrcode_bg.wasm' of undefined
at Object../modules/uranus_qrcode/uranus_qrcode_bg.wasm (http://localhost:3334/0.34621aa454b5fe6ea3b4.worker.js:145:40)

现在 workerize 方法起作用了!
我本来试过workerize-loader + wasm-loader,在dev模式下效果很好,但是一旦编译,原型就不会添加到worker中(怀疑是workerize中的一个bug-加载器,因为所有工作模块的行为都相同)。这确实是 workerize-loader 中的一个错误(参见 workerize-loader failed to work after compiling and Version 1.2.0 does not export function on worker instance in production mode). After upgrading to the workerize-loader 1.2.1,它在开发和生产代码中都有效。
我已经更新了 Master 仓库:https://github.com/aeroxy/react-typescript-webassembly-starter.git
