What is Electron ?

Electron is framework to develop the native desktop application for all major platforms (windows, Mac and Linux)  using HTML , CSS and Javascript.

How to Install Electron?

To install Electron , we need to install nodejs and npm . To check if NodeJs and npm are installed in the system , you can run the below commands in the command line

node -v

npm  -v

Create directory where you will set up the electron project.

Cd myelectronproj

We’re going to run the npm init command to create a package.json, which will store our project settings and dependencies:

npm init -y

Note: The -y flag provides default options automatically

To install electron globally you can run the below command:

npm install electron -g

To install it as a development dependency in your app

npm install electron –save-dev –save-exact

Within your project folder, create a new file called main.js. After that open the package.json file and make a couple updates as shown below:



 “main”: “main.js”,            // Make sure that is main.js

 “scripts”: {

   “start”: “electron .”       // Update this




The scripts property will allow us to run npm start in the console to launch our Electron app, instead of writing electron .

In the main.js , we have to copy and paste the below code:

const {app, BrowserWindow} = require(‘electron’)

const path = require(‘path’)

const url = require(‘url’)

let win

function createWindow () {

 // Create the browser window.

 win = new BrowserWindow({width: 800, height: 600})

 // and load the index.html of the app.


   pathname: path.join(__dirname, ‘index.html’),

   protocol: ‘file:’,

   slashes: true


 // 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



app.on(‘ready’, createWindow)

app.on(‘window-all-closed’, () => {

 if (process.platform !== ‘darwin’) {




app.on(‘activate’, () => {

 if (win === null) {




createWindow() function helps define the actual application window that will be loaded once a user runs the application.

window-all-closed calls app.quote() on non-mac operating systems.

activate calls createWindow() if win is null.

Create an index.html file and copy and paste the below code in that.

<!DOCTYPE html>



   <meta charset=”UTF-8″>

   <title>Hello World!</title>



   <h1>Hello World!</h1>

    <script>We are running Electron <script>document.write(process.versions.electron)</script>.



Run the following command to run the application

npm start
