Anyway simpleschema, collection2 and peerdb can work together

[emmanuelbuah]

First of all, I want to say kudos for putting in the work to get a reactive layer on top of mongo (server-side) to handle declarative updates. Both collection2 and simpleschema solve specific issues, same as peerdb. I personally see peerdb more of a better package to replace collection-hooks but I wonder if peerdb api can be made to work with collection2 and simpleschema. I really see 3 concerns here:

Data schema integrity and validation -> SimpleSchema Collection data schema validation on insert, upsert and update -> Collection2 Provide Collection data hooks on insert, upsert, update and delete -> Collection-hooks || Peerdb

I will personally like to use Peerdb over collection-hooks because of its reactive nature and the ability to handle hooks even if the changes are made by another client. For me peerdb is a clear winner but I cant seem to feel like it will even be much better if it can work in tandem with SimpleSchema and Collection2.

My question is - how do I get the benefit of simpleschema + collection2 + peerdb. Is it be possible to integrate all 3 to work together. Will it be better to integrate peerdb definitions into simpleschema since both of them are in a way defining metadata information. Example, If would be great if we could do something like

//data validation provided by simpleschema 
PostSchema = new SimpleSchema({
    content: {
        type: String,
        optional: false,
    },
   author: {
     type:Object,
     optional: false
   },
   "author.username": {
      type: String
  },
   "author.displayName": {
      type: String
  },
   hits: {
        type: Number
    }
   //etc
});

//peerdb hook through SimpleSchema
PostSchema.References({
    fields: function() {
      return {
        author: Post.ReferenceField(Person, ['username', 'displayName']),
      };
    }
  });

PostSchema.Triggers({
    //trigger definition here ....
  });

Post = new Meteor.Collection('posts');
Post.attachSchema(PostSchema); //provided by collection2

In the approve sample code, simpleschema handles validation (i.e. make sure author's username and displayname is a string), collection2 handle running validation and peerdb extension to simpleschema + collection2 maintains data references and hooks. This is just a thought but I think something along these lines will provide the community with 80% of what its needed for data manipulation. I want to use peerdb now but I also don't want to loose my schema validation checks on my collection (as well as on the client through autoform)

What do you mean? You probably don't check in your template helper if document returned from the client-side copy of data has the document you are searching for. You render templates before all data is available.

I am trying to create some benchmarks and it would be useful to learn about db schemas people use PeerDB for. Care to share?

Reading @PiTopRyan's Nov 2014 remarks, I infer that he was able to use SimpleSchema with PeerDB to offer at least simple schema input validations while using PeerDB collections. This is a valid inference?

@lonniev is very new to meteor and peerdb...
