First of all, we need steps on how we would like to deploy our app to npm.
So far I know, there is a too to manage it https://docs.npm js.com/cli/update.html
we can use it and have both git tags and package.json with specified version

As a second step, we need to add a workflow to publish this package based on the version in package.json, here is the link
https://docs.npmjs.com/creating-and-publishing-scoped-public-packages

Let's start from npm commands we have to run to publish app and going to automate this workflow with CircleCI (WiseEngineering/crispy#4)
