// main.js (MAIN PROCESS)
function createWindow () {
// Create the browser window.
mainWindow = new BrowserWindow({width: 800, height: 600})
// and load the index.html of the app.
mainWindow.loadFile('index.html')
//...
}
<!-- index.html --->
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Hello World!</title>
</head>
<body>
<h1>Hello World!</h1>
<!-- All of the Node.js APIs are available in this renderer process. -->
We are using Node.js <script>document.write(process.versions.node)</script>,
Chromium <script>document.write(process.versions.chrome)</script>,
and Electron <script>document.write(process.versions.electron)</script>.
</body>
<script>
// You can also require other files to run in this process
require('./renderer.js')
</script>
</html>
Demo!
Node.js as a first class citizenĀ
- ECMAScript 2015/ES6 support
- Leverage ~700k npm modules
- You can do what previously had to be done server side
