Cloud Firestore: Node.js Client

This is the Node.js Server SDK for Google Cloud Firestore. Google Cloud Firestore is a NoSQL document database built for automatic scaling, high performance, and ease of application development.

This Cloud Firestore Server SDK uses Google’s Cloud Identity and Access Management for authentication and should only be used in trusted environments. Your Cloud Identity credentials allow you bypass all access restrictions and provide read and write access to all data in your Cloud Firestore project.

The Cloud Firestore Server SDKs are designed to manage the full set of data in your Cloud Firestore project and work best with reliable network connectivity. Data operations performed via these SDKs directly access the Cloud Firestore backend and all document reads and writes are optimized for high throughput.

Applications that use Google's Server SDKs should not be used in end-user environments, such as on phones or on publicly hosted websites. If you are developing a Web or Node.js application that accesses Cloud Firestore on behalf of end users, use the firebase Client SDK.

Note: This Cloud Firestore Server SDK does not support Firestore databases created in Datastore mode. To access these databases, use the Datastore SDK.

A comprehensive list of changes in each version may be found in the CHANGELOG.

Quickstart

Before you begin

1. Select or create a Cloud Platform project.
2. Enable the Cloud Firestore 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/firestore

Using the client library

const {Firestore} = require('@google-cloud/firestore');

// Create a new client
const firestore = new Firestore();

async function quickstart() {
  // Obtain a document reference.
  const document = firestore.doc('posts/intro-to-firestore');

  // Enter new data into the document.
  await document.set({
    title: 'Welcome to Firestore',
    body: 'Hello World',
  });
  console.log('Entered new data into the document');

  // Update an existing document.
  await document.update({
    body: 'My first Firestore app',
  });
  console.log('Updated an existing document');

  // Read the document.
  const doc = await document.get();
  console.log('Read the document');

  // Delete the document.
  await document.delete();
  console.log('Deleted the document');
}
quickstart();

Samples

Samples are in the samples/ directory. Each sample's README.md has instructions for running its sample.

The Cloud Firestore Node.js Client API Reference documentation also contains samples.

Supported Node.js Versions

Our client libraries follow the Node.js release schedule. Libraries are compatible with all current active and maintenance versions of Node.js.

Client libraries targeting some end-of-life versions of Node.js are available, and can be installed via npm dist-tags. The dist-tags follow the naming convention legacy-(version).

Legacy Node.js versions are supported as a best effort:

• Legacy versions will not be tested in continuous integration.
• Some security patches may not be able to be backported.
• Dependencies will not be kept up-to-date, and features will not be backported.

Legacy tags available

• legacy-8: install client libraries from this dist-tag for versions compatible with Node.js 8.

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.
