### Initializing Sketchfab OAuth2 Client and Handling Connection in JavaScript

Source: https://github.com/sketchfab/sketchfab-oauth2/blob/master/index.html

This snippet initializes the Sketchfab OAuth2 client with a predefined configuration including hostname, client ID, and redirect URI. It then attaches an event listener to a 'connect' button, which, when clicked, initiates the OAuth2 connection process. Upon successful authentication, the grant object is logged; otherwise, any errors are caught and logged to the console.

```JavaScript
var config = { hostname: 'sketchfab.com', client_id: 'ig-3miFgAznsYmxUP9VGoN@Chj7ZIrUfAG!UWwne', redirect_uri: 'http://localhost:8000/authSuccess.html' };
var connectButton = document.querySelector('.connect');
var output = document.querySelector('.output');
connectButton.addEventListener('click', function(e){
    var client = new SketchfabOAuth2( config );
    client.connect().then( function onSuccess( grant ) {
        console.log( grant );
    } ).catch( function onError( error ) {
        console.error( error );
    } );
}, false);
```

### Connecting to Sketchfab with OAuth2 in JavaScript

Source: https://github.com/sketchfab/sketchfab-oauth2/blob/master/README.md

This JavaScript snippet initializes the SketchfabOAuth2 client with necessary configuration details, including the hostname, client ID, and redirect URI. It then attempts to establish a connection, handling both successful grant acquisition and potential errors using Promises.

```JavaScript
var config = {
    hostname: 'sketchfab.com',
    client_id: 'INSERT_YOUR_CLIENT_ID_HERE',
    redirect_uri: 'http://example.com/authSuccess.html'
};

var client = new SketchfabOAuth2( config );

client.connect().then( function onSuccess( grant ) {
    console.log( grant );
} ).catch( function onError( error ) {
    console.error( error );
} );
```

### Including SketchfabOAuth2 Library in HTML

Source: https://github.com/sketchfab/sketchfab-oauth2/blob/master/README.md

This snippet demonstrates how to include the SketchfabOAuth2 JavaScript library in an HTML page using a <script> tag. It specifies the source path and type for the script, making the library available for use in the browser.

```HTML
<script src="../dist/sketchfab-oauth2-1.2.0.js" type="text/javascript"></script>
```

### Closing Browser Window with JavaScript

Source: https://github.com/sketchfab/sketchfab-oauth2/blob/master/authSuccess.html

This JavaScript snippet uses `setTimeout` to close the current browser window after a 2-second delay. It's commonly used in OAuth2 flows where a pop-up window needs to close itself after successful authentication, returning control to the parent window or application. No specific dependencies are required beyond a standard browser environment.

```JavaScript
setTimeout(function(){ window.close(); }, 2000);
```
