Update data by uploading files

Hello,
Some users of a Shiny app need to update the data manually and without deploying it. So, I am looking for a way to:

  1. Upload the main file in a dashboard
  2. Save it and keep it there for future interactions until a new fie is uploaded
  3. So far, I have been able to upload the file and save it but:
    • Changes only happen when I turn off and restart the app
    • Using reactive updates the data, but not permanently, every time users reload it they have to upload the data file. This is not optimal.

Any ideas or suggestions on how to do it? Thank you!

I suggest starting here:
