> How to use Node.js and Electron APIs.
2015-08-29 05:46:31 +00:00
All of [Node.js's built-in modules](http://nodejs.org/api/) are available in
Electron and third-party node modules also fully supported as well (including
the [native modules](../tutorial/using-native-node-modules.md)).

Electron also provides some extra built-in modules for developing native
2015-09-04 20:44:40 +00:00
desktop applications. Some modules are only available in the main process, some
2015-09-01 22:42:10 +00:00
are only available in the renderer process (web page), and some can be used in
2015-08-29 05:46:31 +00:00
both processes.
2015-11-12 14:24:11 +00:00
The basic rule is: if a module is [GUI][gui] or low-level system related, then
it should be only available in the main process. You need to be familiar with
the concept of [main process vs. renderer process](../tutorial/quick-start.md#the-main-process)
scripts to be able to use those modules.

2015-08-29 05:46:31 +00:00
The main process script is just like a normal Node.js script:
2014-05-05 06:49:05 +00:00
```javascript
const electron = require('electron');
const app = electron.app;
const BrowserWindow = electron.BrowserWindow;
2014-05-05 06:49:05 +00:00
var window = null;
app.on('ready', function() {
window = new BrowserWindow({width: 800, height: 600});
2015-11-13 08:03:40 +00:00
window.loadURL('https://github.com');
2014-05-05 06:49:05 +00:00
});
```
2015-11-12 14:24:11 +00:00
The renderer process is no different than a normal web page, except for the
extra ability to use node modules:
2014-05-05 06:49:05 +00:00
```html
<!DOCTYPE html>
<html>
2015-11-12 14:24:11 +00:00
<body>
<script>
const remote = require('electron').remote;
console.log(remote.app.getVersion());
2015-11-12 14:24:11 +00:00
</script>
</body>
2014-05-05 06:49:05 +00:00
</html>
```
To run your app, read [Run your app](../tutorial/quick-start.md#run-your-app).

## Destructuring assignment
If you are using CoffeeScript or Babel, you can also use
2016-03-06 07:28:39 +00:00
[destructuring assignment][destructuring-assignment] to make it easier to use
2015-11-12 14:24:11 +00:00
built-in modules:
```javascript
const {app, BrowserWindow} = require('electron')
```
However if you are using plain JavaScript, you have to wait until Chrome fully
supports ES6.
