Quickstart

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
  await datastore.save(task);
  console.log(`Saved ${task.key.name}: ${task.data.description}`);
}
quickstart();

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.
