I would say do both. Allow a "handler" or submit events if there isn't one. Make a method on the main connection for modifying with an ID passed in (needed for when they didn't create it w/ your client) and make one in the returned object (though addNode would probably take a callback instead of returning) that doesn't require the ID.
Also, if you make a good one, claim your prize: http://gun.io/open/23/neo4j-nodejs-adapter On Saturday, March 10, 2012 7:44:13 AM UTC-6, Oni wrote: > > Hi everyone, > > As an exercise to learn node.js, I propossed myself to write a module to > connect node.js with a Neo4j database. > My problem is in how to design the module. > > Neo4j is a graph database, so it basicaly has nodes and relationships > between nodes.
