Usage Example

Retrieving an access token from the Google's OAuth 2.0 authorization server using a service account key (JSON), in Cloudflare Workers environment:

import { getAuthToken } from "web-auth-library";

export default {
  async fetch(req, env) {
    // Get an access token for interacting with Google Cloud Platform APIs.
    const token = await getAuthToken({
      credentials: env.GOOGLE_CLOUD_CREDENTIALS,
      scope: "https://www.googleapis.com/auth/cloud-platform",
    });
    // => {
    //   accessToken: "ya29.c.b0AXv0zTOQVv0...",
    //   type: "Bearer",
    //   expires: 1653855236,
    // }
    return fetch("https://cloudresourcemanager.googleapis.com/v1/projects", {
      headers: {
        authorization: `Bearer ${token.accessToken}`,
      },
    });
  },
} as ExportedHandler;

Where env.GOOGLE_CLOUD_CREDENTIALS is an environment variable / secret containing a base64-encoded service account key obtained from the Google Cloud Platform.
