⚠️ Breaking Changes

Promises have arrived!

Issue: #551
PR: #1704

It's been a long time coming, but we're finally here. We've shipped promise support in the Google Cloud Datastore module!

Do I have to use promises?

Nope, carry on. (But keep reading if you use streams)

How do I use promises?

Don't pass a callback:

var datastore = require('@google-cloud/datastore')();
var query = datastore.createQuery('Kind');

query.run()
  .then(function(data) {
    var entities = data[0];
  })
  .catch(function(err) {});

How do I use a method as a stream?

All of the streaming functionality from our methods have been moved to their own method.

var datastore = require('@google-cloud/datastore')();

- datastore.get()
+ datastore.createReadStream()
   .on('data', function(entity) {})

- datastore.runQuery()
+ datastore.runQueryStream()
   .on('data', function(entity) {})

var transaction = datastore.transaction('transaction-id');

- transaction.get()
+ transaction.createReadStream()
   .on('data', function(entity) {})

- transaction.runQuery()
+ transaction.runQueryStream()
   .on('data', function(entity) {})

var query = datastore.createQuery('Kind');

- query.run()
+ query.runStream()
   .on('data', function(entity) {})
