    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.

    Before you begin

    1. Select or create a Cloud Platform project.

      Go to the projects page

    2. Enable billing for your project.

      Enable billing

    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
      .then(() => {
        console.log(`Saved ${}${}`);
      .catch(err => {
        console.error('ERROR:', err);

    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.
