React-Component: How to load existing react-component into dash?

Hello everyone,

I’m a newbie with web-app. Now I want to build an alert popup in my dash-app by using Reactjs-Popup ( The total reacts-popup files were downloaded and I read the introduction " React for Python Developers: a primer" (, so I know, with commands below “Build the project”, the both bundles and the languages classes files can be generated.
The question now is, how the exist Reactjs-Pop files get coupled with dash package?
I would like to call these self-built package in my (such like dash-core-component).

Thanks in advance.
