Firebase Topic Counter

This little script will output the amount of tokens subscribed to a topic.
You will need to replace the variables with your personal ones in order for it to work.

We used this function in a Lambda which sends the results to a monitoring dashboard.

How to get the variables

Screenshots in the comments.

• Go to the Firebase Console.
