googleapis-common

What is googleapis-common?

The googleapis-common npm package provides common utilities and types for Google API clients. It is used internally by other Google API client libraries to handle common tasks such as authentication, request handling, and response parsing.

What are googleapis-common's main functionalities?

Authentication

This feature allows you to authenticate with Google APIs using the GoogleAuth class. The code sample demonstrates how to create an instance of GoogleAuth, obtain a client, and retrieve the project ID.

const { GoogleAuth } = require('googleapis-common');
const auth = new GoogleAuth({
  scopes: ['https://www.googleapis.com/auth/cloud-platform'],
});

async function authenticate() {
  const client = await auth.getClient();
  const projectId = await auth.getProjectId();
  console.log(`Authenticated with project ID: ${projectId}`);
}
authenticate();

Request Handling

This feature provides a way to handle API requests using the createAPIRequest function. The code sample shows how to set up the parameters for a GET request to a hypothetical Google API endpoint and handle the response.

const { createAPIRequest } = require('googleapis-common');

async function makeRequest() {
  const parameters = {
    options: {
      url: 'https://www.googleapis.com/someapi/v1/resource',
      method: 'GET',
    },
    params: {},
    requiredParams: [],
    pathParams: [],
    context: {},
  };

  const response = await createAPIRequest(parameters);
  console.log(response.data);
}
makeRequest();

Response Parsing

This feature allows you to parse responses from Google API requests. The code sample demonstrates how to make a request and parse the response data.

const { createAPIRequest } = require('googleapis-common');

async function parseResponse() {
  const parameters = {
    options: {
      url: 'https://www.googleapis.com/someapi/v1/resource',
      method: 'GET',
    },
    params: {},
    requiredParams: [],
    pathParams: [],
    context: {},
  };

  const response = await createAPIRequest(parameters);
  const data = response.data;
  console.log(`Parsed data: ${JSON.stringify(data)}`);
}
parseResponse();

Other packages similar to googleapis-common

google-auth-library

The google-auth-library package provides authentication support for Google APIs. It is similar to the authentication feature in googleapis-common but focuses solely on authentication and authorization.

axios

Axios is a popular HTTP client for making requests. While it is not specific to Google APIs, it can be used to handle HTTP requests and responses similarly to the request handling feature in googleapis-common.

googleapis

The googleapis package is a comprehensive client library for accessing Google APIs. It uses googleapis-common internally but provides a higher-level interface for interacting with various Google services.

Quickstart

Before you begin

1. Select or create a Cloud Platform project.

   Go to the projects page

2. Enable billing for your project.

   Enable billing

3. Set up authentication with a service account so you can access the API from your local workstation.

Installing the package

npm install --save googleapis-common

It's unlikely you will need to install this package directly, as it will be installed as a dependency when you install other @google packages.

Versioning

This library follows Semantic Versioning.

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