javascript - Defining a Mongoose schema on-the-fly from a JSON-formatted 'description'

Question

I'm making a web app which allows users to create their own custom MongoDB collections on my server by first 'registering' the schema in a client-side form.

So the user will create a schema client side - say using a form like this: http://r.github.com/annotationsformatter/

So the client-side Js will generate a JSON object of the form, for example:

{
    "collection_name": "person",
    "data": 
    {
        "name": "String",
        "email": "String",
        "id", "Number",
    }
}

Next, the page will send this object to the server, which should convert the stuff in data to a proper Mongoose Schema and create a collection from it, of collection name person.

I'm lost - how would I go about doing this? I'm talking about the conversion-to-schema part.

Answer 1

I have written a node.js library for exactly this purpose: generate mongoose models from .json configuration files.

It's called mongoose-gen. It supports all mongoose types, it has hooks for validators, setters, getters and default values.

Hope it helps.
