Google Cloud Pub/Sub: Node.js Client

release level CircleCI AppVeyor codecov

Cloud Pub/Sub is a fully-managed real-time messaging service that allows you to send and receive messages between independent applications.

Using the client library

  1. Select or create a Cloud Platform project.

  2. Enable billing for your project.

  3. Enable the Google Cloud Pub/Sub API.

  4. Set up authentication with a service account so you can access the API from your local workstation.

  5. Install the client library:

    npm install --save @google-cloud/pubsub

  6. Try an example:

// Imports the Google Cloud client library
const PubSub = require('@google-cloud/pubsub');

// Your Google Cloud Platform project ID
const projectId = 'YOUR_PROJECT_ID';

// Instantiates a client
const pubsubClient = new PubSub({
  projectId: projectId,
});

// The name for the new topic
const topicName = 'my-new-topic';

// Creates the new topic
pubsubClient
  .createTopic(topicName)
  .then(results => {
    const topic = results[0];
    console.log(`Topic ${topic.name} created.`);
  })
  .catch(err => {
    console.error('ERROR:', err);
  });

Versioning

This library follows Semantic Versioning.

This library is considered to be in beta. This means it is expected to be mostly stable while we work toward a general availability release; however, complete stability is not guaranteed. We will address issues and requests against beta libraries with a high priority.
