Quickstart

Before you begin

1. Select or create a Cloud Platform project.
2. Enable the Google Cloud Functions 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/functions

Using the client library

// Imports the Google Cloud client library

// remove this line after package is released
// eslint-disable-next-line node/no-missing-require
const {CloudFunctionsServiceClient} = require('@google-cloud/functions');

// TODO(developer): replace with your prefered project ID.
// const projectId = 'my-project'

// Creates a client
const client = new CloudFunctionsServiceClient();

// project = 'my-project/*/locations/*' // Get the functions for a project.
async function listFunctions() {
  const [functions] = await client.listFunctions({
    parent: `projects/${projectId}/locations/-`,
  });
  console.info(functions);
}
listFunctions();

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/functions@legacy-8 installs client libraries for versions compatible with Node.js 8.

Versioning

This library follows Semantic Versioning.

This library is considered to be 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 stable libraries are addressed with the highest priority.
