Google Cloud Datastore: Node.js Client

release level CircleCI AppVeyor codecov

Node.js idiomatic client for Cloud Datastore.

Cloud Datastore is a NoSQL document database built for automatic scaling, high performance, and ease of application development. While the Cloud Datastore interface has many of the same features as traditional databases, as a NoSQL database it differs from them in the way it describes relationships between data objects.

Read more about the client libraries for Cloud APIs, including the older Google APIs Client Libraries, in Client Libraries Explained.

  3. Enable the Google Cloud Datastore API.

    Enable the API

  4. Set up authentication with a service account so you can access the API from your local workstation.

Installing the client library

npm install --save @google-cloud/datastore

Using the client library

// Imports the Google Cloud client library
const Datastore = require('@google-cloud/datastore');
 
// Your Google Cloud Platform project ID
const projectId = 'YOUR_PROJECT_ID';
 
// Creates a client
const datastore = new Datastore({
  projectId: projectId,
});
 
// The kind for the new entity
const kind = 'Task';
// The name/ID for the new entity
const name = 'sampletask1';
// The Cloud Datastore key for the new entity
const taskKey = datastore.key([kind, name]);
 
// Prepares the new entity
const task = {
  key: taskKey,
  data: {
    description: 'Buy milk',
  },
};
 
// Saves the entity
datastore
  .save(task)
  .then(() => {
    console.log(`Saved ${task.key.name}${task.data.description}`);
  })
  .catch(err => {
    console.error('ERROR:', err);
  });

Versioning

This library follows Semantic Versioning.

This library is considered to be General Availability (GA). This means it is stable; the code surface will not change in backwards-incompatible ways unless absolutely necessary (e.g. because of critical security issues) or with an extensive deprecation period. Issues and requests against GA libraries are addressed with the highest priority.
