DT::renderDataTable not render using HTML UI - MIME type error


using the DT::renderDataTable function is working ok using RStudio and ShinyApps.io, but when I change the UI tu use HTML is still working in RStudio but in ShinyApps.io I have an error in tje browser

"Refused to apply style from because its MIME type ('text/html') is not a supported stylesheet MIME type, and strict MIME checking is enabled"

This is the code

server <- function(input, output) {
output$mytable = DT::renderDataTable({
shinyApp(ui = htmlTemplate("www/index.html"), server)


you can see the error in https://cege.shinyapps.io/TestTabla/

Don't put your template in the www/ directory:


To use an HTML template for the UI, first create an HTML file in your app directory, at the same level as the ui.R , server.R , or app.R files (not in a www/ subdirectory). Here’s an example template for a complete web page,

I can see in the console that the external JS and CSS files are not loaded. Did you include the headcontent() tag in your html file like below:

<!DOCTYPE html>
    <script src="//d3js.org/d3.v3.min.js" charset="utf-8"></script>
    {{ suppressDependencies("d3") }}
    {{ headContent() }}


thanks for your help, finally I use the addResourcePath() to upload all the necessary files and folders. Was useful the resourcePaths() with the working example to understand the folders necessary to add.
