Using this component

Modes

The pwa-simulator can be used in 2 ways:

1. You can enter the PWA's URL in the initially rendered form, and via the pwabuilder-manifest-finder API, the component fetches the corresponding web manifest.
2. The site's URL can be passed as a property to the component, together with the web manifest. Note that the PWA's URL is still needed in this mode to display the icons and other images.

Configuration

All properties are optional and have default values, but for the optimal experience these should be modified as needed. Note that in the HTML markup, property names should be all in lowercase. For more information refer to lit's documentation.

• siteUrl: The PWA's URL. If not defined, the component will initially display a form to input the site's URL (see mode 1 above).
• manifest: The input manifest object. The siteUrl property should be defined if a manifest is given as input.
  • Default:

  {
    name: 'PWA App',
    background_color: '#FFF',
    theme_color: '#E3CEF6',
    categories: [],
    shortcuts: [],
    display: 'standalone',
    description: 'An amazing progressive web app!',
    icons: [
      {
        src: '/assets/icons/icon_512.png',
        sizes: '512x512',
        type: 'image/png'
      }
    ]
  }

• hideEditor: If true, the code editor is hidden and only the preview window is displayed.
  • Default: false
• explanations: Object containing the explanation messages that are displayed when the user interacts with the previewer. initial is the starting message (can be used to suggest an initial action to the user). appWindow, startMenu, jumpList and store are all shown when the respective window is open. If a value isn't specified, the default message is used.
  • Default:

  {
    initial: "Do you see something familiar on the taskbar?",
    appWindow: "The background color, theme color and display attributes determine several UI aspects of your PWA, such as the titlebar.",
    startMenu: "The application's name and icon are used in the start menu.",
    jumpList: "The actions listed on the shortcuts attribute define a context menu that is displayed when right-clicking on the taskbar icon.",
    store: "Screenshots, a complete description and categories will enhance your app's listing in the Microsoft Store."
  }

• explanationDisplayTime: The duration (in milliseconds) of the explanation message display, after which it fades out.
  • Default: 5000 (5 seconds)
