Firebase Messaging + GraphQL on App Engine Flexible

[kushal kundanmal]

I have a NodeJS based web application backend hosted on App Engine Flexible. 

I wanted to create an Event Driven system with GraphQL on express as the main endpoint, and Cloud Function workers triggered by Cloud Pub Sub.

I was thinking of using Firebase Messaging as a provider of real-time updates to the client. 

I just wanted to see if anyone has had experience with a similar layout? 

Any feedback would be greatly appreciated.

Hello Kushal, 

To start with, it may be worthwhile mentioning that the Firebase Cloud Messaging SDK is supported only in pages served over HTTPS. This is due to its use of service workers, which are available only on HTTPS sites.

To assess feasibility and suitability of Firebase Cloud Messaging in your system, you may consider following a good example on the "Set Up a JavaScript Firebase Cloud Messaging Client App" documentation page. 

A quite instructive presentation of the subject in entertaining video format can be found on the "Getting Started with Firebase Cloud Messaging on the Web - Firecasts" page. 

If you'd prefer a fully coded example, you may have a look at "firebase/quickstart-js".
