@google-cloud/common

What is @google-cloud/common?

@google-cloud/common is a library that provides common functionality for Google Cloud Node.js client libraries. It includes utilities for logging, error handling, and making authenticated API requests.

What are @google-cloud/common's main functionalities?

Logging

The logging feature allows you to create and use a logger to log messages at different levels (info, error, etc.).

const { logger } = require('@google-cloud/common');
const log = logger();
log.info('This is an info message');
log.error('This is an error message');

Error Handling

The error handling feature provides a standardized way to create and handle API errors.

const { ApiError } = require('@google-cloud/common');
try {
  throw new ApiError({ message: 'An error occurred', code: 500 });
} catch (err) {
  console.error(err.message); // 'An error occurred'
  console.error(err.code); // 500
}

Authenticated API Requests

This feature allows you to make authenticated API requests to Google Cloud services.

const { Service } = require('@google-cloud/common');
const service = new Service({
  baseUrl: 'https://example.googleapis.com',
  scopes: ['https://www.googleapis.com/auth/cloud-platform']
});
service.request({
  method: 'GET',
  uri: '/v1/resource'
}, (err, response) => {
  if (err) {
    console.error(err);
  } else {
    console.log(response);
  }
});

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 @google-cloud/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-cloud packages.
