I have just updated my contentful-to-neo4j project so that it will by default work on a graphene database hosted in Heroku.
Steps to get this working:
Clone the repo:
git clone https://github.com/chriseyre2000/contentful-to-neo4j
Sign up to heroku, add a credit card, create an empty heroku app.
Add the free graphene db addon (assuming that you have less than 1000 content types).
Install the heroku cli
Open a terminal in the directory that you checked out the repo.
This may require you to login to heroku on the cli.
heroku git:remote -a YOUR_APP_NAME
set the two keys that identify the contentful space:
Once the app has finished restarting:
heroku run loader -a YOUR_APP_NAME
You should now have a full populate graphene database.
You may need to move to a paid tier big enough for your contentful space…
This is surprisingly painless. I only had to add environment variable fallbacks and a Procfile.
