This document discusses ORM over REST in NodeJS. It introduces Node-Vger, a library inspired by HER that aims to provide an ORM-like interface for RESTful resources in NodeJS. Node-Vger handles HTTP requests to retrieve, create, update and delete resources and includes support for authorization, associations and middleware. The challenges of Node-Vger include managing authentication, implementing Active Relation-like scopes, and dealing with associations between resources.

1. ORM over REST in

3. NodeJS newbie
Tried hands on ExpressJS, Socket.IO
Understands basics of a RESTful applications
with NodeJS
Migrated RoR based Front-End to NodeJS

4. Service Oriented Architecture

5. Accessing RESTful Resources
How do we do it in now?
Using HTTP?
http.request(params,callback);

6. How about this?
User.where(name: “Prashant”)
HTTP GET http://api.example.com/users?name=Prashant
===> [{id: 1, name: “Prashant”,email: “prashant@jombay.
com”}]
Note.where(user_id: 1)
### HTTP GET http://api.example.com/notes?user_id=1
===> [{ id: 1, content: “JSFoo2014”, user_id: 1 }]

7. And probably this
var u = new User();
u.name = “Prashant”
u.save
# HTTP POST http://api.yourdomain.com/users
payload: { name: “Prashant” }
===> {id: 1, name: “Prashant”}

8. Introducing Node-Vger
Inspired by “HER” (Not some girl)
https://github.com/remiprev/her
Novice attempt to achieve something like this in
NodeJS
https://github.com/prcongithub/node-vger
Test App: https://github.com/prcongithub/node-vger-
test-app

9. Challenges
Managing Authorization and Authentication
Active Relation like scopes
Dealing with associations
Support for Middlewares
