How to make mongoose connection available globally

in your models folder create index.js

e.g.

    module.exports = function (mongoose,  dbconn) {        return {            modelname:  require("./file" )(mongoose, dbconn),            modelname2:  require("./file2" )(mongoose,  dbconn),   };};

then load it in your main startup file file where you create your db connection via

var models    = require("./models")(mongoose,dbconn);

the example model file in the models folder should look something like this:

module.exports = function (mongoose,  dbconn) {    /*     *      */    var schema = new mongoose.Schema({        /**         * field         * @type String         */        field: String......      });  return dbconn.model("modelname", schema, "collectioname");};

and so on....

I know it has been a while, but i have found this article and i was wondering what you guys think about it, it looks elegant.https://productbuilder.wordpress.com/2013/09/06/using-a-single-global-db-connection-in-node-js/

It basically say to use Node.js global.varName mechanism to share the connection globally.

BTW, i have tried it my self, and it worked seamlessly.

This sample project on GitHub is a brilliantly simple way to accomplish your goal. It's elegant and effective:https://github.com/fbeshears/register_models. The main code is:

(function(){  module.exports = function(){    var mongoose = require('mongoose');    var Schema = mongoose.Schema;     var files = ['kitten.js', 'comments.js'];    var fn = 0;            for(fn in files) {            var path_fn = "./" + files[fn];            var exported_model = require(path_fn);            exported_model(mongoose, Schema);        }    };})();

I make a dir called 'models' under my main app dir and put this in the folder and require it, then call register_models();
