[Select or create a Cloud Platform project][projects]. 1. [Enable billing for your project][billing]. 1. [Enable the Cloud Pub/Sub API API][enable_api]. 1. [Set up authentication][auth] so you can access the API from your local workstation. ### Installing the client library ```bash npm install @google-cloud/pubsub ``` [//]: # "partials.body" ## Samples Samples are in the [`samples/`][homepage_samples] directory. Each sample's `README.md` has instructions for running its sample. [//]: # "samples" ## Supported Node.js Versions Our client libraries follow the [Node.js release schedule](https://github.com/nodejs/release#release-schedule). Libraries are compatible with all current _active_ and _maintenance_ versions of Node.js. If you are using an end-of-life version of Node.js, we recommend that you update as soon as possible to an actively supported LTS version. Google's client libraries support legacy versions of Node.js runtimes on a best-efforts basis with the following warnings: * Legacy versions are not tested in continuous integration. * Some security patches and features cannot be backported. * Dependencies cannot be kept up-to-date. Client libraries targeting some end-of-life versions of Node.js are available, and can be installed through npm [dist-tags](https://docs.npmjs.com/cli/dist-tag). The dist-tags follow the naming convention `legacy-(version)`. For example, `npm install @google-cloud/pubsub@legacy-8` installs client libraries for versions compatible with Node.js 8. ## Versioning This library follows [Semantic Versioning](http://semver.org/).
