How to deploy Reaction Commerce framework (meteor js) on heroku or digitalocean?

Question

MongoDB

Hi all. is someone using react commerce (on meteor js)? According to the description, it seemed interesting to me and I tried to deploy it on heroku and digital ocean. for DO tried this tutorial https://gist.github.com/jshimko/745ca6674884655169... but not sure about mongodb. how to install it correctly? (is it possible to specify an external link, for example, to the mongodb base on heroku). the DO installation option itself seemed more interesting (ssl, nginx, separate droplet) from heroku. but "easy heroku" installation ( https://docs.reactioncommerce.com/reaction-docs/ma... didn't work either. according to console messages tried to set configs Mail_url, meteor_settings...but no. maybe someone had recent experience framework installation on these cloud hostings?
