-
-- Type: `boolean`
-- Default: `false`
-
-If set to `true`, VuePress will automatically generate and register a service worker that caches the content for offline use (only enabled in production).
-
-If developing a custom theme, the `Layout.vue` component will also be emitting the following events:
-
-- `sw-ready`
-- `sw-cached`
-- `sw-updated`
-- `sw-offline`
-- `sw-error`
-
-::: tip PWA NOTES
-The `serviceWorker` option only handles the service worker. To make your site fully PWA-compliant, you will need to provide the Web App Manifest and icons in `.vuepress/public`. For more details, see [MDN docs about the Web App Manifest](https://developer.mozilla.org/en-US/docs/Web/Manifest).
-
-Also, only enable this if you are able to deploy your site with SSL, since service worker can only be registered under HTTPs URLs.

-### serviceWorker
-
-- 类型: `boolean`
-- 默认值: `false`
-
-如果设置成 `true`，VuePress 将会自动生成并且注册一个 service worker，它缓存了那些已访问过的页面的内容，用于离线访问（仅在生产环境生效）。
-
-如果你正在开发一个自定义主题，`Layout.vue` 组件将会自动触发下述的事件：
-
-- `sw-ready`
-- `sw-cached`
-- `sw-updated`
-- `sw-offline`
-- `sw-error`

-::: tip PWA NOTES
-`serviceWorker` 选项仅仅用来控制 service worker，为了让你的网站完全地兼容 PWA，你需要在 `.vuepress/public` 提供 Manifest 和 icons，更多细节，请参见 [MDN docs about the Web App Manifest](https://developer.mozilla.org/en-US/docs/Web/Manifest).
-此外，只有您能够使用 SSL 部署您的站点时才能启用此功能，因为 service worker 只能在 HTTPs 的 URL 下注册。
