<h2>Print any JavaScript console.log messages in the R console</h2>

<h3>Description</h3>

<p>When developing and debugging a Shiny that uses custom JavaScript code,
it can be helpful to use <code>console.log()</code> messages in JavaScript. This
function allows you to see these messages printed in the R console directly
rather than having to open the JavaScript console in the browser to view the
messages.<br /><br />
This function must be called in a Shiny app's server.
</p>

<h3>Usage</h3>

<pre>
showLog()
</pre>

<p>Log messages that cannot be serialized in JavaScript (such as many
JavaScript Event objects that are cyclic) will not be printed in R.
</p>

<p><code><a href="messageFuncs.html">logjs()</a></code>
</p>

<h3>Examples</h3>

<pre>
if (interactive()) {
  library(shiny)

shinyApp(
    ui = fluidPage(
      useShinyjs(),
      textInput("text", "Type something")
    ),
    server = function(input, output) {
      showLog()
      logjs("App started")
      observe({
        logjs(paste("Length of text:", nchar(input$text)))
      })
    }
  )
}
</pre>
