crunchyPublicBody function

Alternate UIs for unauthenticated and unauthorized users

crunchyServer() and crunchyBody() allow you to protect your app with Crunch authentication and authorization. Add these UI contents to your shiny::shinyUI() body to display different content for visitors who are not authenticated with Crunch (crunchyPublicBody()) or who are authenticated but not authorized to access your app (crunchyUnauthorizedBody).

crunchyPublicBody(...)

crunchyUnauthorizedBody(...)

Arguments

• ...: UI elements for your app, to be conditionally rendered

Returns

An empty string; these functions are called for their side effects of registering the UI elements so that crunchyServer() can render them as appropriate.

Examples

## Not run:

# This is the example from crunchyBody(), adding these alternate bodies:
shinyUI(fluidPage(
    tags$head(
        # This is content that will always be rendered
        tags$title("My secure app")
    ),
    crunchyBody(
        # This is content that only is rendered if the user is authorized
        fluidRow(
            column(6, h1("Column 1")),
            column(6, h1("Column 2"))
        )
    ),
    crunchyPublicBody(
        # This is shown to visitors who are not logged into Crunch at all
        h1("Please log into Crunch.")
    ),
    crunchyUnauthorizedBody(
        # This is for Crunch users who don't meet your authorization criteria
        # Perhaps they don't have access to a particular dataset
        h1("You don't have access to this app."),
        tags$div("Contact your_admin@example.com.")
    )
))
