This blog post shows how to build a real-time dashboard solution for stream data analytics using Apache Flink, Elasticsearch, and Kibana., The point from @jcblum above is that Shiny does use websockets, so this functionality is technically available. The problem is that the display libraries you are using are not taking advantage of streaming data. They are doing batch oriented data processing. This is just a function of the (1) easier thing to program, (2) most common use case..
A custom HTML tag in GTM collects the data you want to stream then calls an App Engine URL with its data payload. The app engine URL is sent to a queue to add the data to BigQuery. The data plus a timestamp is put into a BigQuery row. Then to read the data: The Shiny app calls Big Query every X seconds. The data is aggregated Each Shiny application runs in its own protected environment and access is always SSL encrypted. Standard and Professional plans offer user authentication, preventing anonymous visitors from being able to access your applications.
Preparing an application in Shiny requires creating the back end processing code, which has to be stored in a file named server.R and a front end graphical user interface (GUI), placed in a file named ui.R. Both these file names are mandated, as the shiny package will look for these files. I am trying to create a Shiny app to display data that is collected real time.
