Desktop application using Electron for Syncfusion Angular seed

24 May 20245 minutes to read

Electron is a framework which enables the development of cross-platform desktop application using web technologies(HTML,CSS,JavaScript).

The Syncfusion angular-seed application is fully configured to work with Essential Studio for JavaScript Angular components, in which we configured our ej-angular2 library and necessary changes to consume our Angular components.

The below steps depict how to create desktop app of Syncfusion Angular seed application(SystemJS) using Electron.


  • Node.js (v6.x.x or higher)
  • NPM (v5.4.2 or higher)


Clone the seed application

Clone the angular seed application from GitHub repository. Use below command to clone the application.

  • git clone -b systemjs

    To install NPM packages run the below command in root of the cloned seed application.

  • npm install

    Installing Electron dependencies

    electron - The Electron framework lets us write cross-platform desktop applications using JavaScript, HTML and CSS.

    electron-packager - Electron Packager is a command line tool that bundles Electron based application source code with a renamed Electron executable and supporting files into folders ready for distribution.

    Run below set of commands to install electron dependencies which need to run and package the Angular application as desktop app.

  • npm install electron --save-dev
    npm install electron-packager --save-dev

    Configure Electron application window for Electron

    Create JavaScript file main.js at root of application. This main.js file is the startup of electron application. It should create window and it handles the system events. To know more about main process of electron, refer the link here.

    Copy the below code into main.js file.

  • const {app, BrowserWindow} = require('electron')
    // Keep a global reference of the window object, if you don't, the window will
    // be closed automatically when the JavaScript object is garbage collected.
    let win
    function createWindow () {
      // Create the browser window.
      win = new BrowserWindow({width: 800, height: 600})
      // and load the index.html of the app.
      win.loadURL('file://' + __dirname + '/index.html')
      // Open the DevTools.
      // Emitted when the window is closed.
      win.on('closed', () => {
        // Dereference the window object, usually you would store windows
        // in an array if your app supports multi windows, this is the time
        // when you should delete the corresponding element.
        win = null
    // This method will be called when Electron has finished
    // initialization and is ready to create browser windows.
    // Some APIs can only be used after this event occurs.
    app.on('ready', createWindow)
    // Quit when all windows are closed.
    app.on('window-all-closed', () => {
      // On macOS it is common for applications and their menu bar
      // to stay active until the user quits explicitly with Cmd + Q
      if (process.platform !== 'darwin') {
    app.on('activate', () => {
      // On macOS it's common to re-create a window in the app when the
      // dock icon is clicked and there are no other windows open.
      if (win === null) {
    // In this file you can include the rest of your app's specific main process
    // code. You can also put them in separate files and require them here.

    Specify the main.js file in main field of package.json file, which is the startup script of your app. Refer below code snippet for adding main field.

    jQuery configuration

    To resolve the issue jQuery is not defined add below script section into index.html file. Refer the below code snippet.

  • HTML
  • <script>window.$ = window.jQuery = require('jquery');</script>

    Adding NPM script for running Electron app

    To transpile the typescript file run tsc compiler, before start electron app. Here we run the electron app from root folder, add below script into package.json file for running and packaging electron app.

  • "run-electron": "npm run tsc && electron .",
    "build-electron-app": "npm run tsc &&electron-packager . --overwrite"

    Run the electron app

    To run electron app, run below command.

  • npm run run-electron

    Packaging the app

    Packaging the electron app using below command.

  • npm run build-electron-app

    Run the Executable file

    • The electron executable file is created in the location ejangular2-systemjs-starter-win32-x64/ejangular2-systemjs-starter.exe. Double click on the .exe file to launch the application.
