Pre-loader with "No data found" conditional display

These 2 pages illustrate loading data page actions which seem to recommend that both of these conditional displays should ALWAYS be used TOGETHER for large data sets or slow connections, etc.

Being that a “No Data found” could display falsely before the page view has finished loading into the user browser in some cases
therefore Wappler recommends precede this action with a Pre-Loader view to prevent this.

Is this Best Practice almost always in every separate data view page?

Thank you!

You only need to do the Preloader. You don’t have to do both. With the preloader the page will not render until all data has been rendered.
