process.env.GC_PROJECTID = 'gc-project-id'
process.env.GC_KEYPATH = path.join('path/to/gc-key.json')
var GCD = require('gcdatastore')
var namespace = 'example'
var gcd = new GCD(namespace)

var coll = gcd.collection('samples')
var data;

// save object to gcd 
coll.save({test: 'data', one: 'one', date: new Date()}).then(function(res) {
  console.log('save ok')
}).catch(function(err) {
  console.log('save failed', err)
})

// get list, where test='data', result contains list of {_id: 123456, one:'one'}} and is sorted by date, 0 is skipped and count is limited to 1.   
coll.get({test: 'data'}, {one:1}, {limit:1, skip:0, sort:{date:1}}).then(function(res) {
  console.log(res)
  data = res[0]
})

// delete data by _id
coll.delete(data._id).then(function(res) {
  console.log(res)
})
