question on mapping to collections

[alexfrieden]

So we have originally used mongo and are switching to neo4jReactivity. We have a collection bits,

Bits = new Meteor.Collection("bits");

In server, we have a publications.js file to publish what is in the mongo collection. I would like to change that to neo4j results.

Meteor.publish('bits', function() { return Bits.find(); });

What is the best way to do that with Neo4jReactivity? Thanks!

@alexfrieden as you know neo4j doesn't have any collections, so thereis nothing to publish except certain queries. For this purpose please use Meteor.neo4j.call and Meteor.neo4j.methods, they act just like publish/subscribe for mongo

[alexfrieden]

And keep those at the publication layer?

[dr-dimitru]

@alexfrieden Sorry I didn't get your question.

[alexfrieden]

@dr-dimitru let me rephrase, should the cypher queries happen in the client or the server and get pushed to the client, and how would you push it?

[dr-dimitru]

@alexfrieden You may run queries both client and server. But it has same security policy as original mongo isomorphic driver - to avoid security issues manage it via methods/call .

Once you get data via client's query() or from server via call() - retrieved data is reactive, so updates will be pushed automatically

Thanks for the info. We're working towards moving our app to neo4J. How does the fact that we're moving away from Meteor collection affect this: https://github.com/msavin/Mongol/blob/master/documentation/COMPATIBILITY.md

Do you think there's a way to get the best of both - neo4j, yet still retain ability to debug the neo4j "collections"?

[dr-dimitru]

@lifeinchords there is shouldn't be any issues in compatibility of neo4j driver with any other DB in Meteor. You can use Neo4j DB and any other simultaneously

Great this helps a lot!
