Setup your environment

Install Git

There are multiple Git clients available. Install one or install many. Listed below are some of our top picks.

• Windows

• Mac

If you're using Linux, install Git through your distribution's package manager. For example, apt-get -y install git or yum -y install git.

Read Getting Started - Installing Git for more information.

Note that all the examples in this tutorial will be using Git on the command line. You will use command.exe or powershell (your choice) in Windows, Terminal in OS X, or any terminal emulator in Linux.

Ensure a compatible version of R is installed.

You should have R and optionally RStudio installed. Shiny at IQSS supports R 3.5.x to 3.6.x. If you're using R < 3.5.x, upgrade now as there is no guarantee that code built for R < 3.5.x will function when deployed to the Heroku environment.

You can find out the version of R you have installed through RStudio. Enter the following into the R Console.

> R.version.string
[1] "R version 3.6.1 (2019-07-05)"

Install Docker

This step is optional, but, highly reccomended. While you don't need Docker to deploy your Shiny applications to Heroku or develop applications locally, using Docker you'll be able run your Shiny application with the exact same tooling and libraries as in production.

You can download Docker for Windows, OS X, or Linux.

• Mac

• Windows

Alternatively, if using OS X, you can use brew to install docker.

brew cask install docker

Install Heroku

You will need the Heroku CLI in order to properly configure and deploy your R Shiny application.

Follow the Heroku CLI installation instructions.

Now, you'll deploy the Shiny example application to Heroku.
