• commit lint : اول اجازه نداد که کامیت را انجام دهم! با این توضیح که متن کامیت شما باید فرمت کامیت‌های این پروژه را رعایت کند. اگر به تصویر زیر دقت کنید، کامیت‌ها در این پروژه بسیار منظم هستند و هر کسی با هر متنی که دلش خواست کامیتی انجام نمی‌دهد. با یک بررسی کوچک متوجه شدم چطور باید فرمت این پروژه را رعایت کنم و مشکل رفع شد.
