I created React component which shows data retrieved from DB via API (The API is not ArcGIS API for JavaScript, just for searching data) and it works fine.
Then I want to replace the component as a widget on the map.
I created the widget by extending widget class by following references about widget development.
Then I added the component to the widget and compiled the widget.
However it throw an error when I add the widget to the map.
It seems that the app references React module under dojo (https://js.arcgis.com/4.6/dojo/react/).
So I think I need to set some options when I compile the widget.
I am new to React, TypeScript and widget development.
So I probably miss something very basic, but it would be great if I get infromation about how to use React component in widget.
P.S.
I have already checked the React sample Esri and odoe provided, but it does not follow widget development workflow and it uses compiler library. So unfortunately it does not help.
