How to use the cli-color.erase function in cli-color

app.listen(options.port, options.host, function (err, result) {
    if (err) { throw err };
    console.log(clc.erase.screen);
    console.log(clc.red(banner));
    console.log(clc.red('> > > >  Galaxy of Covers dev server running at ' + clc.underline('http://' + options.host + ':' + options.port) + '  < < < <') + '\n');
  });
};

const erase = () => {
	return clc.move(0, -1) + clc.erase.line;
};

module.exports.moveUp = () => {
  process.stdout.write(clc.move.up(1));
  process.stdout.write(clc.erase.line);
};

var
	vm = require('vm'),

	Promise = require('promise'),

	specialColor = require('util').inspect.styles.special,
	clc = require('cli-color'),
	color = clc[specialColor],
	erase = clc.move.up(1) + clc.erase.line;

module.exports = function Evaler (options, console)
{
	var

	if (options.useGlobal)
	{
		vmEvaler = function (script)
		{
			return script.runInThisContext(noDisplay);
		}
	}

.then(function() {
        clearInterval(progressInterval);
        if (!debugging) {
