+ First, install gcloud with npm and require it into your project:
+
+
$ npm install --save gcloud
+
var gcloud = require('gcloud');
+
+
+
+ The gcloud.datastore object gives you some convenience methods, as well as exposes a Dataset function. This will allow you to create a Dataset, which is the object from which you will interact with the Google Cloud Datastore.
+
+
+var datastore = gcloud.datastore;
+var dataset = new datastore.Dataset();
+
+ See the Dataset documentation for examples of how to query the datastore, save entities, run a transaction, and others.
+
+
+
+
+
+ The gcloud.storage object contains a Bucket object, which is how you will interact with your Google Cloud Storage bucket.
+
// The following call will create 100 new IDs from the Company kind, which
-// exists under the default namespace.
-var incompleteKey = datastore.key('Company', null);
-dataset.allocateIds(incompleteKey, 100, function(err, keys) {});
-
-// You may prefer to create IDs from a non-default namespace by providing an
-// incomplete key with a namespace. Similar to the previous example, the call
-// below will create 100 new IDs, but from the Company kind that exists under
-// the "ns-test" namespace.
-var incompleteKey = datastore.key('ns-test', 'Company', null);
-dataset.allocateIds(incompleteKey, 100, function(err, keys) {});
// Delete a single entity.
-dataset.delete(datastore.key('Company', 123), function(err) {});
-
-// Delete multiple entities at once.
-dataset.delete([
- datastore.key('Company', 123),
- datastore.key('Product', 'Computer')
-], function(err) {});
-
-
-
-
-
-
-
-
get(key, callback)
-
-
-
-
-
-
-
-
Retrieve the entities identified with the specified key(s) in the current
-transaction. Get operations require a valid key to retrieve the
-key-identified entity from Datastore.
var key;
-
-// Create a key from the dataset's namespace.
-key = dataset.key('Company', 123);
-
-// Create a key from a provided namespace and path.
-key = dataset.key({
- namespace: 'My-NS',
- path: ['Company', 123]
-});
-
-
-
-
-
-
-
-
runInTransaction(fn, callback)
-
-
-
-
-
-
-
-
Run a function in the context of a new transaction. Transactions allow you to
-perform multiple operations, committing your changes atomically.
-
-
-
-
-
-
-
-
-
Parameters:

Description

-
-
-
-
fn
-
-
-
-
-
-function
-
-
-
-
-
-
-
-
-
-
The function to run in the context of a transaction.
dataset.transaction(function(transaction, done) {
- // From the `transaction` object, execute dataset methods as usual.
- // Call `done` when you're ready to commit all of the changes.
- transaction.get(datastore.key('Company', 123), function(err, entity) {
- if (err) {
- transaction.rollback(done);
- return;
- }
-
- done();
- });
-}, function(err) {});
-
-
-
-
-
-
-
-
runQuery(query, callback)
-
-
-
-
-
-
-
-
Datastore allows you to query entities by kind, filter them by property
-filters, and sort them by a property name. Projection and pagination are also
-supported. If more results are available, a query to retrieve the next page
-is provided to the callback function.
// Retrieve 5 companies.
-dataset.runQuery(queryObject, function(err, entities, nextQuery) {
- // `nextQuery` is not null if there are more results.
- if (nextQuery) {
- dataset.runQuery(nextQuery, function(err, entities, nextQuery) {});
- }
-});
-
-
-
-
-
-
-
-
save(entities, callback)
-
-
-
-
-
-
-
-
Insert or update the specified object(s) in the current transaction. If a
-key is incomplete, its associated object is inserted and its generated
-identifier is returned to the callback.
Google Cloud Datastore is a
-fully managed, schemaless database for storing non-relational data. Use this
-object to create a Dataset to interact with your data, an "Int", and a
-"Double" representation.
Google Cloud Pub/Sub
-is a reliable, many-to-many, asynchronous messaging service from Google Cloud
-Platform.
-
Note: Google Cloud Pub/Sub API is available as a Limited Preview and the
-client library we provide is currently experimental. The API and/or the
-client might be changed in backward-incompatible ways. This API is not
-subject to any SLA or deprecation policy. Request to be whitelisted to use it
-by filling the
-Limited Preview application form.
