node.js production settings

I made a small app in node.js for windows,

i followed a few guides and tips and i downloaded the 'config', and 'cross-env" packages.

I added this part to my package.json -

"scripts": {
        "start": "cross-env SET NODE_ENV=development& nodemon server.js",
        "qa": "cross-env SET NODE_ENV=qa& nodemon server.js",
        "prod": "cross-env SET NODE_ENV=production& nodemon server.js"
    }

I also added 3 json files under the config folder, default.json, production.json and qa.json.

An example which i am planning to use the config package for is :

var config = require('config');
var connectionString = config.get('connectionString');

Now i scanned quite a few posts about a solution but nothing seem to help so far, when i am trying to run "npm prod" or "npm qa" i am getting the following message :

F:\MeanApp>npm prod

Specify configs in the ini-formatted file:
    C:\Users\me\.npmrc
or on the command line via: npm <command> --key value
Config info can be viewed via: npm help config

So far i failed to figure out the root of the problem.

Solution

As the error message is trying to tell you, npm has no such command; custom scripts do not directly become npm commands.

Instead, use npm run to run a script.
