+# @vue/cli-plugin-pwa
+
+> pwa plugin for vue-cli
+
+The service worker added with this plugin is only enabled in the production environment (e.g. only if you run `npm run build` or `yarn build`). Enabling service worker in a development mode is not a recommended practice, because it can lead to the situation when previously cached assets are used and the latest local changes are not included.
+
+Instead, in the development mode the `noopServiceWorker.js` is included. This service worker file is effectively a 'no-op' that will reset any previous service worker registered for the same host:port combination.
+
+If you need to test a service worker locally, build the application and run a simple HTTP-server from your build directory. It's recommended to use a browser incognito window to avoid complications with your browser cache.
+
+## Configuration
+
+Configuration is handled via the `pwa` property of either the `vue.config.js`
+file, or the `"vue"` field in `package.json`.
+
+- **pwa.workboxPluginMode**
+
+  This allows you to the choose between the two modes supported by the underlying
+  [`workbox-webpack-plugin`](https://developers.google.com/web/tools/workbox/modules/workbox-webpack-plugin).
+
+  - `'GenerateSW'` (default), will lead to a new service worker file being created
+  each time you rebuild your web app.
+
+  - `'InjectManifest'` allows you to start with an existing service worker file,
+  and creates a copy of that file with a "precache manifest" injected into it.
+
+  The "[Which Plugin to Use?](https://developers.google.com/web/tools/workbox/modules/workbox-webpack-plugin#which_plugin_to_use)"
+  guide can help you choose between the two modes.
+
+- **pwa.workboxOptions**
+
+  These options are passed on through to the underlying `workbox-webpack-plugin`.
+
+  For more information on what values are supported, please see the guide for
+  [`GenerateSW`](https://developers.google.com/web/tools/workbox/modules/workbox-webpack-plugin#full_generatesw_config)
+  or for [`InjectManifest`](https://developers.google.com/web/tools/workbox/modules/workbox-webpack-plugin#full_injectmanifest_config).
+
+- **pwa.name**
+
+  - Default: "name" field in `package.json`
+
+    Used as the value for the `apple-mobile-web-app-title` meta tag in the generated HTML. Note you will need to edit `public/manifest.json` to match this.
+
+- **pwa.themeColor**
+
+  - Default: `'#4DBA87'`
+
+- **pwa.msTileColor**
+
+  - Default: `'#000000'`
+
+- **pwa.appleMobileWebAppCapable**
+
+  - Default: `'no'`
+
+    This defaults to `'no'` because iOS before 11.3 does not have proper PWA support. See [this article](https://medium.com/@firt/dont-use-ios-web-app-meta-tag-irresponsibly-in-your-progressive-web-apps-85d70f4438cb) for more details.
+
+- **pwa.appleMobileWebAppStatusBarStyle**
+
+  - Default: `'default'`
+
+- **pwa.assetsVersion**
+
+  - Default: `''`
+
+    This option is used if you need to add a version to your icons and manifest, against browser’s cache. This will append `?v=<pwa.assetsVersion>` to the URLs of the icons and manifest.
+
+- **pwa.manifestPath**
+
+  - Default: `'manifest.json'`
+
+    The path of app’s manifest.
+
+- **pwa.manifestOptions**
+
+  - Default: `{}`
+
+    The object will be used to generate the `manifest.json`
+
+    If the following attributes are not defined in the object, the options of `pwa` or default options will be used instead.
+      - name: `pwa.name`
+      - short_name: `pwa.name`
+      - start_url: `'.'`
+      - display: `'standalone'`
+      - theme_color: `pwa.themeColor`
+
+- **pwa.iconPaths**
+
+  - Defaults:
+
+    ```js
+    {
+      favicon32: 'img/icons/favicon-32x32.png',
+      favicon16: 'img/icons/favicon-16x16.png',
+      appleTouchIcon: 'img/icons/apple-touch-icon-152x152.png',
+      maskIcon: 'img/icons/safari-pinned-tab.svg',
+      msTileImage: 'img/icons/msapplication-icon-144x144.png'
+    }
+    ```
+
+    Change these values to use different paths for your icons.
+
+### Example Configuration
+
+```js
+// Inside vue.config.js
+module.exports = {
+  // ...other vue-cli plugin options...
+  pwa: {
+    name: 'My App',
+    themeColor: '#4DBA87',
+    msTileColor: '#000000',
+    appleMobileWebAppCapable: 'yes',
+    appleMobileWebAppStatusBarStyle: 'black',
+
+    // configure the workbox plugin
+    workboxPluginMode: 'InjectManifest',
+    workboxOptions: {
+      // swSrc is required in InjectManifest mode.
+      swSrc: 'dev/sw.js',
+      // ...other Workbox options...
+    }
+  }
+}
+```
+
+## Installing in an Already Created Project
+
+``` sh
+vue add pwa
+```
+
+## Injected webpack-chain Rules
+
+- `config.plugin('workbox')`
