This template provides a rough and ready rudimentary example of how to use ArcGIS Maps SDK for JS with React and Typescript to display a simple map with points.
Clone the repo and then run npm install to install the dependencies.
The ArcGIS SDK is huge and will take a while.
Run locally by npm run dev and you should see an interactive map and table.
The point data is mocked JSON for random location in the middle of WA desert.
