Shiny hyperlink relative path to a file

Question

This may be very simple, but I cannot find the right syntax despite searching through postings:

I want to create a hyperlink on my shiny web page which when clicked should open a file from the same location where the application is.

Here is a sample code :

 library(shiny); 
 shinyApp( ui = fluidPage(a("test_hyperlink",href="./readme.txt")), 
           server = function(input, output) {  } )

readme.txt is in the same location as this application .

I tried the following with no success :

file://readme.txt # relative path
file:///srv/shiny-server/myApp/readme.txt # absolute path
href://./readme.txt # relative path
href:///srv/shiny-server/myApp/readme.txt # absolute path

Any help?

Answer 1

create a folder called 'www' inside your shiny app directory 'appFolder'.

Put the file 'readme.txt' in the www folder.

File path is href="readme.txt"

You have to use 'runApp(appFolder)' command to start your shiny app. It then can access all local files inside the www folder.
