Electron Apps can easily be debugged and tested using nodejs.
Install curl and nvm:
sudo apt install curl curl -sL https://raw.githubusercontent.com/creationix/nvm/v0.33.11/install.sh -o install_nvm.sh bash install_nvm.sh source ~/.profile
Install an older LTS version of npm: nvm ls-remote can be used to see a list of available versions
nvm ls-remote nvm install 8.17.0 nvm use 8.17.0
Electron Example Apps
There is a couple of example apps available on the electron github page:
Hello World App
git clone https://github.com/electron/electron-quick-start
Electron API Demos
git clone https://github.com/electron/electron-api-demos
Electron Simple Samples
git clone https://github.com/electron/simple-samples
Installing and launching the example apps
To install the apps navigate to the apps in the terminal and install them.
cd electron-api-demos npm install
or
cd simple-samples/activity-monitor npm install
Electron apps can be launched when logged in remotely via UART or SSH:
DISPLAY=:0 npm start
… or when logged in locally using a keyboard on the eval kit:
npm start
Electron Packager
The electron packager is used to package Electron apps into OS-specific executables.
For use from the CLI
npm install electron-packager -g
Package an application for Trizeps 8 with Debian:
electron-packager <PATHTOSOURCE> <PROJECTNAME> --platform=linux --arch=arm64
The application will be placed in a subfolder of the active directory.
Running Electron Apps in Kiosk Mode
Electron apps can be set up to be launched in kiosk mode by adding that option to the main BrowserWindow in the main .js file (usually app.js or main.js)
Simply add
WINDOWNAME.setKiosk(true);
to the options below the WINDOWNAME = new BrowserWindow({ … }) section.
