A Server-Side File System Viewer for Shiny

Provides functionality for client-side navigation of the server side file system in shiny apps. In case the app is running locally this gives the user direct access to the file system without the need to "download" files to a temporary location. Both file and folder selection as well as file saving is available.

This package extends the functionality of shiny by providing an API for client side access to the server file system. As many shiny apps are run locally this is equivalent to accessing the filesystem of the users own computer, without the overhead of copying files to temporary locations that is tied to the use of fileInput().

The package can be installed from CRAN using install.packages('shinyFiles').


The package is designed to make it extremely easy to implement file system access. An example of implementing a file chooser would be:

In the ui.R file

    shinyFilesButton('files', label='File select', title='Please select a file', multiple=FALSE)

In the server.R file

shinyServer(function(input, output) {
    shinyFileChoose(input, 'files', root=c(root='.'), filetypes=c('', 'txt'))

It is equally simple to implement directly in your custom html file as it only requires a single <button> element. The equivalent of the above in raw html would be:

<button id="files" type="button" class="shinyFiles btn" data-title="Please select a file" data-selecttype="single">
    File select

For an overview of all the different modules try the shinyFilesExample() function in the package. It gives an overview of all the necessary code, along with descriptions and working examples.
