runUrl {shiny} | R Documentation

## Run a Shiny application from a URL

### Description

`runUrl()` downloads and launches a Shiny application that is hosted at a downloadable URL. The Shiny application must be saved in a .zip, .tar, or .tar.gz file. The Shiny application files must be contained in the root directory or a subdirectory in the archive. For example, the files might be `myapp/server.r` and `myapp/ui.r`. The functions `runGitHub()` and `runGist()` are based on `runUrl()`, using URL's from GitHub (https://github.com) and GitHub gists (https://gist.github.com), respectively.

### Usage

    runUrl(url, filetype = NULL, subdir = NULL, destdir = NULL, ...)

    runGist(gist, destdir = NULL, ...)

    runGitHub(repo, username = getOption("github.user"), ref = "master",
      subdir = NULL, destdir = NULL, ...)

### Arguments

`url` | URL of the application.
`filetype` | The file type (`".zip"`, `".tar"`, or `".tar.gz"`. Defaults to the file extension taken from the url.
`subdir` | A subdirectory in the repository that contains the app. By default, this function will run an app from the top level of the repo, but you can use a path such as '`"inst/shinyapp"`.
`destdir` | Directory to store the downloaded application files. If `NULL` (the default), the application files will be stored in a temporary directory and removed when the app exits
`...` | Other arguments to be passed to `runApp()`, such as `port` and `launch.browser`.
`gist` | The identifier of the gist. For example, if the gist is https://gist.github.com/jcheng5/3239667, then `3239667`, `'3239667'`, and `'https://gist.github.com/jcheng5/3239667'` are all valid values.
`repo` | Name of the repository.
`username` | GitHub username. If `repo` is of the form `"username/repo"`, `username` will be taken from `repo`.
`ref` | Desired git reference. Could be a commit, tag, or branch name. Defaults to `"master"`.

      # Can run an app from a subdirectory in the archive
      runUrl("https://github.com/rstudio/shiny_example/archive/master.zip",
        subdir = "inst/shinyapp/")
    }
