Launching from the command line
Installing Node.js® and NPM on Mac What’s Node.js® and NPM? Node.js® is a JavaScript-based environment which you can use to create web-servers and networked applications. To run a script application, double-click the script in the Finder, just like you would do to launch any other application. The script opens and begins running. When running a script app outside of Script Editor, you can’t view a list of the script’s events and results.
You can also run VS Code from the terminal by typing 'code' after adding it to the path:
- Launch VS Code.
- Open the Command Palette (⇧⌘P (Windows, Linux Ctrl+Shift+P)) and type 'shell command' to find the Shell Command: Install 'code' command in PATH command.
- Restart the terminal for the new
$PATH
value to take effect. You'll be able to type 'code .' in any folder to start editing files in that folder.
Note: If you still have the old
code
alias in your .bash_profile
(or equivalent) from an early VS Code version, remove it and replace it by executing the Shell Command: Install 'code' command in PATH command.Alternative manual instructions
Instead of running the command above, you can manually add VS Code to your path, to do so run the following commands:

Mojave privacy protections
After upgrading to macOS Mojave version, you may see dialogs saying 'Visual Studio Code would like to access your {calendar/contacts/photos}.' This is due to the new privacy protections in Mojave and is not specific to VS Code. The same dialogs may be displayed when running other applications as well. The dialog is shown once for each type of personal data and it is fine to choose Don't Allow since VS Code does not need access to those folders. You can read a more detailed explanation in this blog post.
Updates
VS Code ships monthly releases and supports auto-update when a new release is available. If you're prompted by VS Code, accept the newest update and it will get installed (you won't need to do anything else to get the latest bits).
Note: You can disable auto-update if you prefer to update VS Code on your own schedule.
Preferences menu
You can configure VS Code through settings, color themes, and custom keybindings and you will often see mention of the File > Preferences menu group. On a macOS, the Preferences menu group is under Code, not File.

Common questions
Why do I see 'Visual Studio Code would like access to your calendar.'
If you are running macOS Mojave version, you may see dialogs saying 'Visual Studio Code would like to access your {calendar/contacts/photos}.' This is due to the new privacy protections in Mojave discussed above. It is fine to choose Don't Allow since VS Code does not need access to those folders.

VS Code fails to update
If VS Code doesn't update once it restarts, it might be set under quarantine by macOS. Follow the steps in this issue for resolution.
In developing the DSM2 HYDRO Viz Tool, we were faced with deciding how to deploy a Shiny app that required interaction with large local files. I first heard about the possibility of using Electron to deploy Shiny apps as standalone desktop applications in this talk by Katie Sasso, but it wasn't until I discovered the R Shiny Electron (RSE) template that I decided to take the plunge.
UPDATE (2020-09-06): The approach described in this post is fragile and I no longer use it. Here are a couple of alternatives: electricShine and photon.
R Shiny Electron Build Process
The R Shiny Electron (RSE) template includes only very basic instructions for how to get started with this process (and they clearly specify that it is not ready for production). There were considerable gaps in my understanding that left me flailing while trying to get things to work (especially on Windows). Below I am describing what I did to get up and running but I make no argument that this process represents best practices.
Basic setup
The RSE template doesn't mention anything about the arguably obvious steps of installing Node, Electron, and Electron Forge.
- Install Node with one of the pre-built installers available from the Node website.
After installing Node, Electron and Electron Forge are installed using
npm
from the command line. On Windows, Node installs a Node.js command prompt that I used for any npm
and electron-forge
commands (rather than the default Windows command prompt). The Node installer provides Windows users with the option to automatically install the necessary tools, including Chocolatey. I checked the box to automatically install these tools, but I'm not sure if this step is necessary to build the Electron app. - Run
npm install -g electron-forge
in the Terminal (macOS) [1] or Node.js command prompt (Windows) to install Electron Forge globally. - Clone or download the GitHub repository for the RSE template.
Edit: The RSE template hasn't been updated in over a year and the Node ecosystem evolves rapidly. I forked the repository, searched for each dependency package in
package.json
via the npm website, and updated version numbers to the latest version found in the npm package search. I also removed electron-forge
from the devDependencies because it is installed globally. If you are having trouble with the original repository, you should try the forked version of the RSE template repository.Run Js Online
Build process on macOS
The RSE template repository includes a simple Shiny app. As a first step, I recommend following the steps below to confirm that you can build the executable with the simple app before trying your own app. At the end of this post, I will write more about extra steps required to build the executable for the DSM2 Viz Tool.
- Open the Terminal and change the directory to the location of
r-shiny-electron
orr-shiny-electron-master
(see how to use the Terminal). - Run
npm install --save-dev electron
in the Terminal to install Electron locally. - Run
npm install
to set up the project in ther-shiny-electron
directory.
You will get lots of warnings about outdated packages [2]. I tried to fix the warnings with
npm audit fix
, but ran into problems and started over with a fresh clone of the RSE template.- Download R binary for macOS by running
./get-r-mac.sh
[3]. - Identify and download packages used in Shiny app by running
Rscript add-cran-binary-pkgs.R
. - Run
npm start
to test if app launches (and works correctly). - If the app works correctly, run
electron-forge make
to build the macOS executable.
The build process will create a folder called
Out
in the r-shiny-electron
directory. In Out/r-shiny-electron-darwin-x64
, you will have an executable (r-shiny-electron.app
) that you can run to test that the app is working correctly. In Out/make
, you will have a zip file that contains the executable but is better for distributing because of the smaller file size [4].It is possible to build a Windows installer on macOS, but it 'takes forever.' I tried going down this road, but bailed after the process had run for 2 hours without finishing because I had access to a Windows machine for building the app.
Build process on Windows
As mentioned in the macOS section, I recommend following the steps below to confirm that you can build the executable with the simple Shiny app available through the RSE template before trying your own app.
- Install Cygwin and the wget package, which is not installed by default. The
wget
function is used in./get-r-win.sh
. If you havewget
from another installation process, then you might be able to skip this step. - Install
innoextract
with Chocolatey by runningchoco install innoextract
from the command prompt with administrative privileges, i.e., right click on the command prompt and chooseRun as administrator
.innoextract 1.8
is required. If you have a previous version of innoextract installed, then runchoco upgrade innoextract
[5]. - Open the Node.js command prompt and change the directory to the location of
r-shiny-electron
orr-shiny-electron-master
. - Run
npm install --save-dev electron
in the Node.js command prompt to install Electron locally. - Run
npm install
in the Node.js command prompt to set up the project in ther-shiny-electron
directory. - Change the directory to
r-shiny-electron
in Cygwin, e.g., typecd
in the Cygwin terminal and drag ther-shiny-electron
folder to Cygwin to paste the path. Use Notepad++ to open./get-r-win.sh
and confirm that the EOL characters are in Unix format. Download R binary for Windows by running./get-r-win.sh
in Cygwin. - Identify and download packages used in the Shiny app by running
Rscript add-cran-binary-pkgs.R
from the RStudio Terminal. Remember to first change the directory tor-shiny-electron
. You may also need to install theautomagic
package first. - Run
npm start
in the Node.js command prompt to test if the app launches (and works correctly) [6]. - If the app works correctly, run
electron-forge make
in the Node.js command prompt to build the Windows executable. https://popbrown374.weebly.com/blog/downloaded-excel-allow-apps-keychain-mac-not-working.You can triage your inbox by scheduling when you are going to take care of an email. The essential mac apps.
The build process will create a folder called
Out
in the r-shiny-electron
directory. In Out/make/squirrel.windows/x64
, you will have an installer executable called r-shiny-electron-1.0.0 Setup.exe

Customizing build process for DSM2 Viz Tool
After working through the build process on the r-shiny-electron example app, I downloaded a fresh version of the RSE template, renamed the
r-shiny-electron
directory to DSM2-Viz-Tool
, removed the app.R
file from DSM2-Viz-Tool/shiny
, and replaced it with the files for the DSM2 Viz Tool Shiny app. I also opened package.json
in a text editor and changed a few fields (e.g., name, productName, version, description, author). Run Js App Mac Pro
Next, I started working through the build process described above. However, before running
npm start
I needed to add the binary files for the rhdf5
and Rhdf5lib
packages because Rscript add-cran-binary-pkgs.R
doesn't find Bioconductor packages. You can find where R packages are installed on your machine by running .libPaths()
from the R console. I manually copied and pasted the rhdf5
and Rhdf5lib
folders from the location indicated by the output of .libPaths()
to DSM2-Viz-Tool/r-mac/library
and DSM2-Viz-Tool/r-win/library
on macOS and Windows, respectively. Then, I was able to finish the build process.Working through this process involved plenty of frustration (because of my knowledge gaps), but it was extremely satisfying to arrive at the end goal of packaging the DSM2 Viz Tool as a standalone desktop application.
[1] On macOS, you may need to provide permission to access
/usr/local/lib/node_modules
. Solve the permission error by running sudo chown -R $USER /usr/local/lib/node_modules
from the Terminal. [2] I personally find all the security warnings alarming, but this article suggests that I shouldn't worry about it.
[3] The R version specified in this shell script should be the same R version that was used to build the shiny app.
[4] On macOS Catalina, the first time that you run the app, you will be prompted to give permmission to access the file system. After granting permission, you may need to quit the app and then launch it again.
[5] If that doesn't work, run
choco uninstall innoextract
and then run choco install innoextract
. [6] One of the requirements is that
git
is installed. An installer is available here.
