mongodb-data-service

MongoDB Data Service: an API on top of (currently) the MongoDB Node Driver and (some day) mongodb-scope-client.

Installation

npm install --save mongodb-data-service

Usage

Instantiating the service.

const Connection = require('mongodb-connection-model');
const DataService = require('mongodb-data-service');
 
var service = new DataService(new Connection({
  hostname: '127.0.0.1',
  port: 27018,
  ns: 'data-service'
}));

Connecting to the server.

Once the service is ready, it will also emit a readable event.

service.connect((err) => assert.equal(null, err)})
  .on('readable', () => console.log('Connected!'));

API
