Question

given a RESTful web service that allows different users to post different articles

For defining the GET function on the server-sidem
i suppose there should be async functions like list, getTopViewed, getTopFavorite etc functions on the server-side

is the following correct then?

exports.get = function(req, res) {

    db.articles.list(function etc)
    db.articles.getTopViewed(function etc)
    db.articles.getTopFavorite(function etc)
}

NOTE: where list, getTopViewed and getTopFavorite are defined in another JavaScript file

In another JS file:

exports.list = function(callback){
  // acts as async callback 
  var result = ArticleModel.find({}, function(err, articles){
    callback(null, articles)                                                    
  });
  return result;
}

Answer 1

I recommend using something like Connect or Express. It has a router that makes this a bit easier. Setup and usage look something like this:

var express = require("express"),
    db = require('./yourdb.js');

var app = express.createServer();

app.configure(function(){
    app.use(app.router);
});

app.get("/articles/", function(req, res){
    db.list(function(err, articles){
       res.writeHead(200);
       // you probably want to do something more complex here
       res.end(JSON.stringify(articles));
    });
});

app.get("/articles/top", function(req, res){
    // res.end(<top articles go here>);
});

Here’s a link to the docs for Express’ router: Application Routing
