How to create schema for neo4j graph database in nodejs?

Question

I was thinking, How we can prevent user/developer from adding unwanted nodes/relationships/properties?

What I read was - we should impose those schema's at application level. So, how can we do that in Node.js?

Is there any example on this? Or can someone post some code here?

Answer 1

It depends how your applications works.

1. You can create your own validation in your application, but it depends on the type of your application.

2. Better option is to create your own unmanaged extension for Neo4j. You can use Transaction Event API for that - http://graphaware.com/neo4j/transactions/2014/07/11/neo4j-transaction-event-api.html

3. GraphAware provides paid extensions for schema enforcemen - http://graphaware.com/enterprise/
