I thought of shifting this app from npm global command to a curl based app. I can add the country filter but for the country filter, there is a separate file /lib/byCountry.js.

Also, country filter checks needs to be done in /bin/index.js. If the argument is coming fetch data from /lib/byCountry.js file. I am using a module country-code-lookup to search the country from user input. Check app.js.

I am happy to make it a global npm app, which would also reduce some load on my server :)
