Deploy without exposing app keys

[gilfuser]

Hi.
I'm making an app based on yours.
I would like to ask you how could I deploy it, let's say also in Heroku, without exposing the Pusher app keys.

best regards,
Gil

Hi 👋
I’d recommend including your key and secret I’m environment variables when deploying to heroku. You can find out more about how to do that in the heroku docs on config vars

That’s how we solve similar problems at pusher!

Hi @leesio
Thank you for your response.
I managed to use config vars in server.js but not in datachannel-demo.js because I can not require there. Is there a way to do it?

EDIT: Answering to myself: no, there isn't and is not necessary to do it.
