Cbez

Couchbase Made Easy for Node.js, the original Couchbase Node.js module is not quick and easy for map/reduce, no chained queries, etc. This project Cbez tries to make everything as simple as possible for developers when utilising Couchbase in a project.

This is an ES6 module to be imported with ES6 'import' keyword.
