DSRethinkDBAdapter

rethinkdb adapter for js-data

js-data-rethinkdb Slack Status npm version Travis CI npm downloads Coverage Status

Example App

js-data-examples/server/rethinkdb

Quick Start

npm install --save js-data js-data-rethinkdb

The adapter will look for a table option on your resource definitions, or default to using the name of your resource to select from the right table.

var JSData = require('js-data');
var DSRethinkDBAdapter = require('js-data-rethinkdb');

var adapter = new DSRethinkDBAdapter({
  host: '123.456.68.987',
  db: 'my_db'
});
var store = new JSData.DS();
store.registerAdapter('rethinkdb', adapter, { default: true });

// "store" will now use the rethinkdb adapter for all async operations
