Before we dive in to the actual development, we need to do some preparation work.
1. Add Quasar Electron Mode
In order to develop/build a Quasar Electron app, we need to add the Electron mode to our Quasar project. What this does is that it yarn installs some Electron packages and creates
$ quasar mode add electron
Every Electron app has two threads: the main thread (deals with the window and initialization code – from the newly created folder
/src-electron) and the renderer thread (which deals with the actual content of your app from
The new folder has the following structure:
├── icons/ # Icons of your app for all platforms
| ├── icon.icns # Icon file for Darwin (MacOS) platform
| ├── icon.ico # Icon file for win32 (Windows) platform
| └── icon.png # Tray icon file for all platforms
├── electron-preload.js # (or .ts) Electron preload script (injects Node.js stuff into renderer thread)
└── electron-main.js # (or .ts) Main thread code
A note for Windows Users
If you run into errors during npm install about node-gyp, then you most likely do not have the proper build tools installed on your system. Build tools include items like Python and Visual Studio. Fortunately, there are a few packages to help simplify this process.
The first item we need to check is our npm version and ensure that it is not outdated. This is accomplished using npm-windows-upgrade. If you are using yarn, then you can skip this check.
Once that is complete, we can then continue to setup the needed build tools. Using windows-build-tools, most of the dirty work is done for us. Installing this globally will in turn setup Visual C++ packages, Python, and more.
Note: April 2019
In Powershell.exe (Run as Admin)
npm install --global windows-build-tools seems to fail at the moment with errors pointing to python2 and vctools. You can get around this with Chocolatey. One-liner install:
Set-ExecutionPolicy Bypass -Scope Process -Force; iex ((New-Object System.Net.WebClient).DownloadString(‘https://chocolatey.org/install.ps1’))
and then run
choco upgrade python2 visualstudio2017-workload-vctools.
At this point things should successfully install, but if not then you will need a clean installation of Visual Studio. Please note that these are not problems with Quasar, but they are related to NPM and Windows.
2. Start Developing
If you want to jump right in and start developing, you can skip the previous step with “quasar mode” command and issue:
$ quasar dev -m electron
# passing extra parameters and/or options to
# underlying "electron" executable:
$ quasar dev -m electron -- --no-sandbox --disable-setuid-sandbox
# when on Windows and using Powershell:
$ quasar dev -m electron '--' --no-sandbox --disable-setuid-sandbox
This will add Electron mode automatically, if it is missing. It will open up an Electron window which will render your app along with Developer Tools opened side by side.
