I want to use Nodejitsu to host my Node.js app. The app also uses Neo4j. Does Nodejitsu provide any kind of support for that? Or do I need to host Neo4j separately (and pay for all network traffic)?
Nodejitsu doesn't support native Neo4j integration. If you can host a Neo4j service or find one you can use it, and for node.js applications you can use the neo4j api with https://github.com/thingdom/node-neo4j
I will try to find the best answer for you, if I can find anything about Neo4j hosting i will update this question.
