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);
}
});

winston
Winston is a versatile logging library for Node.js. It offers more advanced logging features compared to @google-cloud/common but does not include other utilities like error handling or authenticated requests.
request
Request is a simplified HTTP client for Node.js. It provides similar functionality for making HTTP requests but is now deprecated in favor of more modern alternatives like axios.

Quickstart
Installing the client library
npm install @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.
Versioning
This library follows Semantic Versioning.
This library is considered to be General Availability (GA). This means it
is 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 GA libraries
are addressed with the highest priority.
