Endless loop, re-runs code every time file change is detected.

hotload.js

var co = require('co')
var Promise = require("bluebird")
var chokidar = require('chokidar')

var hotloadFile = 'hotload.js'

var watcher = chokidar.watch( hotloadFile )
function waitForHotload()
{
	return new Promise( (fulfill, reject) => watcher.once( 'change', fulfill ) )
}

co( function*()
{ 
	try 
	{
		// Wait for hotload file change loop
		while (true)
		{
			try
			{
				delete require.cache[ require.resolve( `./${hotloadFile}`) ]
				var ret = yield require( `./${hotloadFile}` )(rl, driver, crawler)
				if ( ret )
					break
			}
			catch (err)
			{
				console.log( err )
			}
			yield waitForHotload();
		}
	} catch (err) {
		console.log(err)
	}
