I want to understand quite advanced features of shiny:
- How to make Shiny faster
- How to make Shiny asynchronous
- How to make Shiny scalable
In order to demonstrate, I tried code available in various links such as https://speakerdeck.com/jcheng5/r-promises. But when I tried the code, there were only errors even after installing necessary packages and libraries.
Could you please share a demo code to understand these concept.
Thanks and Regards
