[Reference][Snippet][MongooseJS]: Tailable cursor example

mongoosejs.cursors.tailable.js

// This example shows how to use tailable cursors in MongoDB using mongoosejs
// IMPORTANT:  The collection must be created as "capped" or this will raise err. 
//             At time of writing, there is no built-in way to create capped collection using MongooseJS.

var mongoose = require("mongoose");
mongoose.connect(connect_string);

Model = mongoose.model(model_name);
Model.connection.find(query, {tailable:true}, function(err, cursor){
  if (err){
    return console.log(err) 
  }

  cursor.each(function(err, doc){
    // do stuff to doc
  });
});
