## Introduction

shinyMobile contains a set of useful functions to help you setting the layout as best as possible. It contains a predefined input, namely input$deviceInfo:

    shiny::shinyApp(
      ui = f7Page(
        title = "My app",
        f7SingleLayout(
          navbar = f7Navbar(
            title = "Access device info",
            hairline = FALSE,
            shadow = TRUE
          ),
          # main content
          verbatimTextOutput("info")
        )
      ),
      server = function(input, output) {
        output$info <- renderPrint({
          input$deviceInfo
        })
      }
    )

The following fields are returned:

- `input$deviceInfo$os`, returns a string containing your OS
- `input$deviceInfo$desktop`, TRUE or FALSE (if you are running the app on your laptop or desktop)
- `input$deviceInfo$standalone`, TRUE or FALSE (standalone, namely whether you access the app like a native app)
- `input$deviceInfo$webview`, TRUE or FALSE (webview)
- `input$deviceInfo$electron`, TRUE or FALSE (electron)

There are other fields, with less inportance:

- `input$deviceInfo$ios`, TRUE or FALSE (if you are running under iOS)
- `input$deviceInfo$android`, TRUE or FALSE (if you are running under android)
- `input$deviceInfo$androidChrome`, TRUE or FALSE (if you are running under android with Chrome)
- `input$deviceInfo$iphone`, TRUE or FALSE (if you have an iphone)
- `input$deviceInfo$ipod`, TRUE or FALSE (if you have an ipod)
- `input$deviceInfo$ipad`, TRUE or FALSE (if you have an ipad)
- `input$deviceInfo$edge`, TRUE or FALSE (if you are using edge)

## Example

Below the example displays a card only when the app is on desktop.

    shiny::shinyApp(
      ui = f7Page(
        title = "My app",
        f7SingleLayout(
          navbar = f7Navbar(
            title = "Access device info",
            hairline = FALSE,
            shadow = TRUE
          ),
          # main content
          uiOutput("card"),
          textOutput("userAgent"),
        )
      ),
      server = function(input, output) {

        output$userAgent <- renderText(input$deviceInfo$desktop)

        # generate a card inkly for desktop
        output$card <- renderUI({
          if (input$deviceInfo$desktop) {
            f7Card(
              "This is a simple card with plain text,
              but cards can also contain their own header,
              footer, list view, image, or any other element."
            )
          }
        })
      }
    )
