ReactJS application as a library [on hold]

Before I ask a question, let me tell you that I am pretty new in ReactJS.

So, few months ago, we created an application that client requred from us using create-react-app command, which means that webpack.confing.js and .babelrc are closed for modifications.

Currently, we have to switch the same one into JS Snippet, actually to have only one file included in head tag, and new instance of it like:

...
new Application({name: "Firstname Lastname"}).render();
...

…which can be embeded every where…

It would be good if you could send me some solutions or hints. I would appreciate it.

Thanks :-)
