Cloud Pub/Sub is a fully-managed real-time messaging service that allows you to send and receive messages between independent applications.
-
Set up authentication with a service account so you can access the API from your local workstation.
-
Install the client library:
npm install --save @google-cloud/pubsub -
Try an example:
// Imports the Google Cloud client library
const {PubSub} = require('@google-cloud/pubsub');
async function quickstart(
projectId = 'your-project-id', // Your Google Cloud Platform project ID
topicName = 'my-topic' // Name for the new topic to create
) {
// Instantiates a client
const pubsub = new PubSub({projectId});
// Creates the new topic
const [topic] = await pubsub.createTopic(topicName);
console.log(`Topic ${topic.name} created.`);

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.
