I have a requirement to use Google Cloud Pub/Sub API directly from Browser ( similar to GA script). I was wondering how can in handle Auth without requiring going through a back-end server.
I want to invoke the Cloud Pub/Sub API directly from the browser. I tried and it says i need to authenticate first , my issue is how to secure the Auth Token.
Is there any javascript library that is available which i can use in Browser ( not backend) to invoke the Google Pub/Sub API.
Thanks in advance

Google Cloud Pub/Sub provides messaging between applications. Cloud Pub/Sub is designed to provide reliable, many-to-many, asynchronous messaging between applications. Publisher applications can send messages to a "topic" and other applications can subscribe to that topic to receive the messages.
The Pub/Sub server sends each message as an HTTPS request to the subscriber client at a pre-configured endpoint.
The Pub/Sub service delivers messages to push endpoints from the same Google Cloud region that the Pub/Sub service stores the messages.
The general approach in Javascript for authorizing and making authorized requests to Google APIs is shown at https://developers.google.com/api-client-library/javascript/samples/samples#AuthorizingandMakingAuthorizedRequests -- it's not specific to the Cloud Pubsub API, but it should work for all Google APIs. Similarly, https://developers.google.com/api-client-library/javascript/start/start-js for general Javascript access to Google APIs.
