save object in module and access it from different modules

Question

I am using the following code to parse json data and keep it internally in my module, for example when the server is (like npm server.js) I'm using the function parse which parses the json files.
At the end these parsed jsons are kept in the object configObj and I want that during user request's(via express) to get this object in the router module or other modules.

How do I achieve this?

var configObj;
parse = function () {
        return fs.readFileAsync(file, 'utf8')
            .then(function (res) {
                return JSON.parse(res)
            }).then(function (jsonObj) {
                configObj = jsonObj;
                return jsonObj;
            })
....
        })
    };
    module.exports = {
        parse: parse,
        configObj: configObj
    }

The parse function is called only once and I want to access to the configObj many times in different modules.

You could use something like node-persist:

var storage = require('node-persist');
storage.setItem('config', configObj);
console.log(storage.getItem('config'));
