Using Electron and TypeScript

What are Electron and TypeScript?

Electron is a framework used to develop desktop applications. It allows you to create cross-platform applications using HTML, CSS, and JavaScript. TypeScript, on the other hand, is a superset of JavaScript that provides type safety and makes it easier to develop larger applications. When these two technologies are combined, it is possible to develop powerful and scalable desktop applications.

Getting Started with Electron and TypeScript

Installation

To develop an application using Electron and TypeScript, you first need to have Node.js installed on your system. Then, let’s follow the steps to include Electron and TypeScript in your project.

npm init -y
npm install electron typescript --save-dev

With the above commands, we have created a new Node.js project and installed the Electron and TypeScript libraries.

Creating the Project Structure

You should set up your project’s file structure. You can start with a structure like this:

• src/
     main.ts
     index.html
• package.json
• tsconfig.json

After setting up this structure, you can configure your tsconfig.json file as follows:

{
  "compilerOptions": {
    "target": "ES6",
    "module": "commonjs",
    "outDir": "dist",
    "strict": true,
    "esModuleInterop": true
  }
}

Creating a Simple Electron Application

Now, in your main.ts file, you can create a simple Electron application:

import { app, BrowserWindow } from 'electron';

function createWindow() {
  const win = new BrowserWindow({
    width: 800,
    height: 600,
    webPreferences: {
      nodeIntegration: true
    }
  });

  win.loadFile('index.html');
}

app.whenReady().then(createWindow);

app.on('window-all-closed', () => {
  if (process.platform !== 'darwin') {
    app.quit();
  }
});

app.on('activate', () => {
  if (BrowserWindow.getAllWindows().length === 0) {
    createWindow();
  }
});

This code sample creates the main window of your Electron application. To start the application, you can use the npx electron . command.

Conclusion

It is quite easy to develop cross-platform desktop applications using Electron and TypeScript. In this article, we learned how to integrate the Electron framework and TypeScript and how to create a simple application. You can add more details on top of this basic information to develop more complex applications.
