...Keystone starts with best practices for setting up your MV* application, and makes it easy to manage your templates, views and routes. IDs, Strings, Booleans, Dates and Numbers are the building blocks of your database. Keystone builds on these with useful, real-world field types like name, email, password, address, image and relationship fields (and more). Whether you use it while you're building out your application, or in production as a database content management system, Keystone's Admin UI will save you time and make managing your data easy. Sometimes, async code can get complicated to do simple things.
