Questions tagged [waterline]

Waterline is an adapter-based ORM for Node. It is included with the Sails.js framework.

Waterline provides a uniform API for accessing stuff from different kinds of databases, protocols, and 3rd party APIs. That means you write the same code to get users, whether they live in MySQL, LDAP, MongoDB, or Facebook.

At the same time, Waterline aims to learn lessons and maintain the best features from both Rails' ActiveRecord and Grails' Hibernate ORMs.

Waterline uses the concept of an Adapter to translate a predefined set of methods into a query that can be understood by your data store. Adapters allow you to use various datastores such as MySQL, PostgreSQL, MongoDB, Redis, etc. and have a clear API for working with your model data.

It also allows an adapter to define it's own methods that don't necessarily fit into the CRUD methods defined by default in Waterline. If an adapter defines a custom method, Waterline will simply pass the function arguments down to the adapter.
