Real-Time Data Updates Issue in Shiny Dashboard with tea

[hyfzi]

1. When building a Shiny dashboard using teal, the running app.r does not display the latest data contents in real-time when the data is updated。
   2.I have consulted relevant resources, which suggest using functions like reactiveFileReader. However, when building a Shiny app with teal, teal provides encapsulated modules. How should I proceed to make modifications?
   3.I'm a beginner in R Shiny. Can anyone help me solve this issue?

I don't think real-time data updates is possible at the moment within teal framework.

The closest that I could think of is to create some event to re-trigger the data read using teal_data_module(), then run something like invalidateLater() combined with JS (i.e sendCustomMessage) to automatically run the event (i.e. click a button) on a time interval.

Yes, I think so too. A while ago, my colleague asked the person in charge, and their response was that real-time data updates cannot be implemented for the time being.

If this is still an issue, have you tried adding your data to the teal app with teal_data_module and using reactiveFileReader there?

Thank you for your response. I haven't had much time to learn teal recently, but when I have some free time, I'll try the methods you mentioned. Thank you!
