# @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.

    • '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?" 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 or for InjectManifest.

  • 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 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:

      {
        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.
