ORM that uses Keyword 'await'

Waterline is a next-generation storage and retrieval engine, and the default ORM used in the Sails framework ( I prefer using hapi ) 

It provides a uniform API for accessing stuff from different kinds of databases and protocols. That means you write the same code to get and store things like users, whether they live in MySQL, MongoDB, neDB, or Postgres.

Waterline strives to inherit the best parts of ORMs like ActiveRecord, Hibernate, and Mongoose, but with a fresh perspective and emphasis on modularity, testability, and consistency across adapters.
