This is a helper function for ExpressJS handler creation. The aim is factorization of code : querying - waiting for results - writing JSon response for a HTTP Rest Server.

Usage

Usage example :

var MONGOWH = require('mongo-web-handler');

app.route("/items")
  .get( MONGOWH.createMongoWebHandler( logger, "ItemListQuery"
    function( req, res, resultsCallbackFunc ){
      mongoItemsCollection.find( {}, resultsCallbackFunc );
      })
  );

The function createMongoWebHandler returns an ExpressJS handler function. It takes parameters :

• a logger : a log4js logger for tracing ;
• a query name : for log output
• a query function for your querying logic with one argument, the result callback function so the handler can parse the results end return a JSon response.
