Progressive Web App (PWA)

Configuration

{shinyMobile} is PWA capable, meaning that you can make sure your app uses the correct assets to be used as a PWA. This feature is automatically handled by f7Page() if allowPWA is TRUE.


When set to TRUE, your app is set up to use both a service-worker.js script and a manifest.webmanifest file that you will provide.


To create these necessary assets for your PWA, you can use {charpente}:

remotes::install_github("RinteRface/charpente")
library(charpente)
set_pwa(APP_PATH, ...)

Where APP_PATH is the app location. Currently, it only works if the app is inside a package like with {golem}. If your app is not in a package, you may copy the www folder of the gallery app, which provides:

It is really easier with {charpente}, the reason why we strongly recommend to develop your app inside a package.


But that’s not all that’s needed! When you set allowPWA = TRUE in f7Page(), the app will also attach the Google PWA compatibility script, called PWACompat, which will help with PWA compatibility. More specifically, PWACompat brings the Web App Manifest to non-compliant browsers for better PWAs. This mostly means creating splash screens and icons for Mobile Safari, as well as supporting IE/Edge’s Pinned Sites feature. It basically assures that the manifest.webmanifest file has a wider support.

Using your PWA

The first step is to deploy your app somewhere. It doesn’t matter where (shinyapps.io, Posit Connect, your own server, etc.), but you will need a URL to access it.


Then, you can follow these steps to install your app on your mobile device.


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 that are part of the browser UI.

Limitations

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