@Lykhoyda how do we envision to deploy the react package? I have this question after reading the deploy files for the react package

[mpetrunic]

We don't need prod deployment (we are building library here), we just need deploy previews.
It's probably best to rebase against #58

@wainola the deployment will serve the static file like index.html. The react project is empty for now, so it's just a preparation of the code for future code deployments.
