Using custom "homepage" property

When using a custom homepage property in your package.json, you may encounter Service Worker registration issues. Consider the following package.json:

// package.json
  "homepage": "/my-app"

This will treat the /my-app path as the home directory for your application. However, MSW will still expect you to serve the worker script at the root.

To account for that, you have to provide an explicit Service Worker URL as the serviceWorker.url option when starting the worker:

// src/index.js
// Read the package.json file to grab the "homepage" value.
import packageJson from '../package.json'
if (process.env.NODE_ENV === 'development') {
  const { worker } = await import('./mocks/browser')
  await worker.start({
    serviceWorker: {
      // Provide a custom worker script URL, taking
      // the "homepage" into account.
      url: `${packageJson.homepage}/mockServiceWorker.js`,
