Client API Reference

Quickstart

Before you begin

Select or create a Cloud Platform project.

Go to the projects page
Enable billing for your project.

Enable billing
Enable the Google Cloud Datastore API.

Enable the API
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.
