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 ([https://www.npmjs.com/package/reactjs-popup](https://www.npmjs.com/package/reactjs-popup)). The total reacts-popup files were downloaded and I read the introduction " React for Python Developers: a primer" ([https://dash.plot.ly/react-for-python-developers](https://dash.plot.ly/react-for-python-developers)), 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 app.py (such like dash-core-component).

Thanks in advance.
