In rstudio/shinycoreci: CI Testing for shiny

Custom inputs

In this example, the picture-taking control is a custom input control. shinyvalidate lets custom input controls decide where and how to display their input validation feedback.

Note: As of this writing, this app doesn't work in RStudio; view it in an external browser like Chrome or Firefox instead.

Try pressing the Submit button without taking a picture first; notice that the validation feedback message appears within the input control. This is because the custom input binding code for this control contains setInvalid() and clearInvalid() methods.

(If you'd like a packaged camera input widget for your actual Shiny app, consider the shinyviewr function from the shinysense package.)

This is a slimmed down version of the actual app so that testing is less complicated.
