Before you begin

  1. Select or create a Cloud Platform project.
  2. Enable billing for your project.
  3. Enable the App Hub API API.
  4. 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/apphub

Using the client library

 * This snippet has been automatically generated and should be regarded as a code template only.
 * It will require modifications to work.
 * It may require correct/in-range values for request initialization.
 * TODO(developer): Uncomment these variables before running the sample.
 *  Required. Project and location to list Discovered Services on.
 *  Expected format: `projects/{project}/locations/{location}`.
// const parent = 'abc123'
 *  Optional. Requested page size. Server may return fewer items than
 *  requested. If unspecified, server will pick an appropriate default.
// const pageSize = 1234
 *  Optional. A token identifying a page of results the server should return.
// const pageToken = 'abc123'
 *  Optional. Filtering results.
// const filter = 'abc123'
 *  Optional. Hint for how to order the results.
// const orderBy = 'abc123'

// Imports the Apphub library
const {AppHubClient} = require('@google-cloud/apphub').v1;

// Instantiates a client
const apphubClient = new AppHubClient();

async function callListDiscoveredServices() {
  // Construct request
  const request = {

  // Run request
  const iterable = apphubClient.listDiscoveredServicesAsync(request);
  for await (const response of iterable) {



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

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. If you are using an end-of-life version of Node.js, we recommend that you update as soon as possible to an actively supported LTS version.

Google's client libraries support legacy versions of Node.js runtimes on a best-efforts basis with the following warnings:

  • Legacy versions are not tested in continuous integration.
  • Some security patches and features cannot be backported.
  • Dependencies cannot be kept up-to-date.

Client libraries targeting some end-of-life versions of Node.js are available, and can be installed through npm dist-tags. The dist-tags follow the naming convention legacy-(version). For example, npm install @google-cloud/apphub@legacy-8 installs client libraries for versions compatible with Node.js 8.


This library follows Semantic Versioning.

This library is considered to be in preview. This means it is still a work-in-progress and under active development. Any release is subject to backwards-incompatible changes at any time.
