title: How can I deploy a shiny app to Heroku
body: <p>I have a shiny app and want to deploy it to Heroku. I tried to follow the steps as mentioned in:
  <a href="https://github.com/btubbs/heroku-buildpack-shiny" rel="noreferrer">https://github.com/btubbs/heroku-buildpack-shiny</a></p>
  
  <p>I created a git Git repository and put the R files into it. Then, I created an app in heroku and tell Heroku to use a custom buildpack for my app. But, I was not be able to enable Heroku websockets support.
  Error is:
  Couldn't find that feature.</p>
  
  <p>I can't figure out how to deal with this problem. Is there any other way to deploy the shiny app to Heroku?</p>
