Demo

Progressive Web App (PWA)

Configuration

shinyMobile is PWA capable, meaning that it can be displayed full screen on many mobile devices. This feature is automatically handled by f7Page() if allowPWA is TRUE (it leverages the Google PWA compatibility script).

Below is an example showing the manifest.json file:

{
  "name": "My App",
  "short_name": "My App",
  "description": "My App",
  "lang": "en-US",
  "start_url": "https://dgranjon.shinyapps.io/miniUI2Demo/",
  "display": "standalone",
  "icons": [
    {
      "src": "icons/128x128.png",
      "sizes": "128x128",
      "type": "image/png"
    },
    {
      "src": "icons/144x144.png",
      "sizes": "144x144",
      "type": "image/png"
    },
    {
      "src": "icons/152x152.png",
      "sizes": "152x152",
      "type": "image/png"
    },
    {
      "src": "icons/192x192.png",
      "sizes": "192x192",
      "type": "image/png"
    },
    {
      "src": "icons/256x256.png",
      "sizes": "256x256",
      "type": "image/png"
    },
    {
      "src": "icons/512x512.png",
      "sizes": "512x512",
      "type": "image/png"
    }
  ]
}

Be sure to replace the start_url with your own app url. Also, add a custom name, even though this can be modified later when adding the PWA to your IOS apps. shinyMobile has an helper to create the manifest, that is create_manifest. Finally, there are tools such as appsco and app-manifest, to create those custom icons and splash screens, if you need to.

Add the PWA to your desktop Apps

Copy the url of your app in your mobile web browser (iOS: Safari and Andoid: Chrome). In this example this is: https://dgranjon.shinyapps.io/miniUI2Demo/. It opens like a classic web app, with top and bottom ugly navigation bars.

• Select the share button located in the bottom bar of your Iphone/Ipad. For Android, you may do something similar. Importantly, Chrome for iOS does not support this feature, that’s why I recommend using Safari.
• Click on “Add to Home Screen”
• Choose a relevant name and click on OK.
• The app will be added to your IOS/Android Apps. In case you want custom icons, replace the content of the www folder with your own.

Limitations

It is actually quite complex to guarantee that all mobile platforms are supported. The PWA compatibility script will work in most of the case. If not, please open an issue here, to help improving it!
