Overview of Electron
Electron is an open-source system made by GitHub that lets you use web tools to make desktop apps. It bundles your web code with a Chromium browser and Node.js runtime.
Key Components:
- Main Process: Manages the application lifecycle and native interface.
- Renderer Process: Runs the user interface using Chromium.
- Preload Scripts: Provide controlled access to Node.js APIs in the renderer process.
Electron apps are essentially web applications that can access operating system-level APIs.
Setting Up Your Development Environment
Create desktop application using React and Electron:
Prerequisites:
- js (v16 or above recommended)
- npm or yarn
- A code editor (Visual Studio Code preferred)
Installation:
Verify your Node and npm versions:
node -v
npm -v
Install create-react-app:
npx create-react-app react-desktop-app
cd react-desktop-app
Install Electron as a development dependency:
npm install –save-dev electron
Creating a React Application
React provides a solid foundation for UI development. Step-by-step guide to React desktop app development.
Use create-react-app to bootstrap the app quickly:
npx create-react-app my-desktop-app
cd my-desktop-app
This generates a basic React project structure with pre-configured tooling.
Integrating Electron with React
Create Electron Main Process File
Create a new file public/electron.js:
const { app, BrowserWindow } = require(‘electron’);
const path = require(‘path’);
function createWindow() {
const win = new BrowserWindow({
width: 800,
height: 600,
webPreferences: {
preload: path.join(__dirname, ‘preload.js’),
contextIsolation: true,
},
});
win.loadURL(‘http://localhost:3000’);
}
app.whenReady().then(createWindow);
Add Electron Start Script to package.json
“main”: “public/electron.js”,
“scripts”: {
“start”: “react-scripts start”,
“electron”: “concurrently \”npm start\” \”wait-on http://localhost:3000 && electron .\””
}
Install supporting tools:
npm install concurrently wait-on –save-dev
Run the app:
npm run electron
Project Structure and Configuration
Recommended structure:
my-desktop-app/
├── public/
│ ├── electron.js
│ └── preload.js
├── src/
│ ├── components/
│ ├── App.js
│ └── index.js
├── package.json
└── README.md
This structure separates Electron-specific and React-specific code.
Using Electron Features in Your App
File System Access
const fs = require(‘fs’);
fs.writeFile(‘example.txt’, ‘Hello from Electron!’, err => {
if (err) throw err;
});
Notifications
new Notification({ title: ‘Notification’, body: ‘Electron works!’ }).show();
Dialogs
const { dialog } = require(‘electron’);
dialog.showOpenDialog({ properties: [‘openFile’] }).then(result => {
console.log(result.filePaths);
});
Use contextBridge in preload.js to expose functions securely:
const { contextBridge, ipcRenderer } = require(‘electron’);
contextBridge.exposeInMainWorld(‘api’, {
notify: (message) => ipcRenderer.send(‘notify’, message),
});
Building and Packaging the Application
Use electron-builder to package your app:
Install electron-builder:
npm install –save-dev electron-builder
Update package.json:
“build”: {
“appId”: “com.example.reactdesktopapp”,
“mac”: { “target”: “dmg” },
“win”: { “target”: “nsis” },
“linux”: { “target”: “AppImage” }
},
“scripts”: {
“pack”: “electron-builder –dir”,
“dist”: “electron-builder”
}
Build the App:
npm run build
npm run dist
Output installers will be available in the dist/ directory.
Distributing the Desktop App
Once packaged, distribute your app via:
- GitHub Releases
- Your website
- Microsoft Store (Windows)
- Mac App Store (requires notarization)
