Thank you @ronenlu. It's a pleasure to contribute to such a useful tool, even though it was a relatively small increment.

Suggested change

	models: models,
	models: files.reduce((models, file) => {
	if (file !== "index.ts" && file.endsWith(".ts")) {
	models.push(absolutePath + "/" + file)
	}
	return models;
	}, []),

More JS'ish but just a suggestion.
