Dad

Composable data stores for node.js and the browser. Dad's small ~300 SLOC codebase implements only methods that are common in most datastores. This includes models, validation and persistance.

No assumptions about your backend are made. Through adapters you can synchronize your data with any backend. Official adapters are a WIP.

Installation

$ npm i --save dad
