Google Cloud Internet of Things (IoT) Core: Node.js Client

Node.js idiomatic client for Cloud IoT Core.

Google Cloud Internet of Things (IoT) Core is a fully managed service for securely connecting and managing IoT devices, from a few to millions. Ingest data from connected devices and build rich applications that integrate with the other big data services of Google Cloud Platform.

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

Quickstart

Before you begin

Select or create a Cloud Platform project.
Enable billing for your project.
Enable the Google Cloud Internet of Things (IoT) Core API.
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/iot

Using the client library

const iot = require('@google-cloud/iot');
const client = new iot.v1.DeviceManagerClient();

async function quickstart() {
  const projectId = await client.getProjectId();
  const parent = client.locationPath(projectId, 'us-central1');
  const [resources] = await client.listDeviceRegistries({parent});
  console.log(`${resources.length} resource(s) found.`);
  for (const resource of resources) {
    console.log(resource);
  }
}
quickstart();

Samples

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

The Google Cloud Internet of Things (IoT) Core 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.
