## Quickstart

### Installing the client library

```bash
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.



The [Google Cloud Common Node.js Client API Reference][client-docs] documentation
also contains samples.

## Supported Node.js Versions

Our client libraries follow the [Node.js release schedule](https://nodejs.org/en/about/releases/).
Libraries are compatible with all current _active_ and _maintenance_ versions of
Node.js.

Client libraries targetting some end-of-life versions of Node.js are available, and
can be installed via npm [dist-tags](https://docs.npmjs.com/cli/dist-tag).
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](http://semver.org/).


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.
