		### Node.js
		The following example shows how to start `run-headless-chromium` from Node.js,
		and terminate the process in a graceful way. Note that the page from the example
		does not call `console.info('All tests completed!0')`, so the browser would stay
		around indefinitely if we do not explicitly kill it.

		```javascript
		// spawn has the same API as child_process.spawn, minus the command argument.
		// See the "spawn" method at https://nodejs.org/api/child_process.html
		var spawnHeadlessChromium = require('run-headless-chromium').spawn;

		var proc = spawnHeadlessChromium([
		// Flags forwarded to Chromium:
		'https://example.com/some_page_that_does_not_print_exit_message',
		], {
		stdio: 'inherit',
		});
		proc.on('close', function() {
		clearTimeout(delayedExit);
		console.log('Headless Chromium exited!');
		});
		var delayedExit = setTimeout(function() {
		console.log('Chrome did not exit within a few seconds, sending SIGINT...');
		// Graceful exit - allow run-headless-chromium to exit Chrome and Xvfb.
		proc.kill('SIGINT');
		// If you do proc.kill(); then Chrome and Xvfb may still hang around.
