  • file extension: .csv, .tsv, .rds
  • MIME type: application/JSON, image/png

9.1.2 Server

In the server, we work with a data frame with a special structure. There are 4 columns:

• name - name of the file on user’s computer
• size - file size in bytes. Default 5 MB; adjust with shiny.maxRequestSize option.
• type - MIME type of the file
• datapath - file path on the server. Temporary.
