Question

我有一个电子应用，其运行角度为8+。我正在调用从node_modules导入的函数。如果我直接在我的组件中调用此函数，它将正常工作。如果我尝试在Web Worker中调用相同的函数，它将导致构建失败。

// component file
const worker = new Worker('./dead-link-checker.worker', { type: 'module' });
        worker.onmessage = ({ data }) => {
            console.log(`page got message: ${data}`);
        };
        worker.postMessage({
            domainName: this.domainName,
            links: this.linksService.links
        });

// webworker file
import { deadLinkChecker } from 'dead-link-checker';
import { tester } from './test';

addEventListener('message', async ({ data }) => {
  console.log('in the workerer', data);

  // Breaks everything
  await deadLinkChecker(data.domainName, undefined, data.links);

  // Works fine
  tester();
  postMessage('link checking complete', undefined);
});

错误：

在angular中使用nodejs脚本之前，我曾遇到过此类错误，并且我使用过this之类的解决方案来解决它。这似乎不是一个相同的问题，因为如果在Web worker之外使用导入的deadLinkChecker函数，效果很好。

使用导入的功能使Web Worker崩溃
