Quickstart

Before you begin

1. Select or create a Cloud Platform project .
2. Enable billing for your project .
3. Enable the IAM Service Account Credentials 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/iam-credentials 

Using the client library

 // Imports the Google Cloud client library

const {IAMCredentialsClient} = require(' @google-cloud/iam-credentials 
');

// TODO(developer): replace with your prefered project values.
// The service account must be granted the roles/iam.serviceAccountTokenCreator role
// const serviceAccount = 'ACCOUNT_EMAIL_OR_UNIQUEID'
// const scopes = 'my-scopes', e.g., 'https://www.googleapis.com/auth/iam'

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

async function generateAccessToken() {
  const [token] = await client.generateAccessToken({
    name: `projects/-/serviceAccounts/${serviceAccount}`,
    scope: [scopes],
  });
  console.info(token);
}
generateAccessToken();

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 .
