Quickstart

Before you begin

1. Select or create a Cloud Platform project.
2. Enable billing for your project.
3. Enable the Dataflow API.
4. Set up authentication with a service account so you can access the API from your local workstation.

Installing the client library

npm install @google-cloud/dataflow

Using the client library

// Imports the Google Cloud client library

const {TemplatesServiceClient} = require('@google-cloud/dataflow');

// TODO(developer): replace with your prefered project ID.
// const projectId = 'my-project'
// TODO(developer): replace with your bucket path.
// const gcsPath = 'gs://<bucket>/path'

// Creates a client
const client = new TemplatesServiceClient();

//TODO(library generator): write the actual function you will be testing
async function getTemplate() {
  const template = await client.getTemplate({
    projectId,
    gcsPath,
  });
  console.info(template);
}
getTemplate();

Supported Node.js Versions

Our client libraries follow the Node.js 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. The dist-tags follow the naming convention legacy-(version). For example, npm install @google-cloud/dataflow@legacy-8 installs client libraries for versions compatible with Node.js 8.

Versioning

This library follows Semantic Versioning.

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