    Google Cloud Datastore: Node.js Client

    release level npm version codecov

    Cloud Datastore Client Library for Node.js

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

    Table of contents:


    Before you begin

    1. Select or create a Cloud Platform project.
    2. Enable the Google Cloud Datastore API.
    3. Set up authentication with a service account so you can access the API from your local workstation.

    Installing the client library

    npm install @google-cloud/datastore

    Using the client library

    // Imports the Google Cloud client library
    const {Datastore} = require('@google-cloud/datastore');
    // Creates a client
    const datastore = new Datastore();
    async function quickstart() {
      // 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
      console.log(`Saved ${}: ${}`);

    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.
