How to Tell Whether a Material Is in Edit Mode or Render Mode

Simple scenario

You can use props.__designMode:

In design mode, __designMode is "design".

In render mode, __designMode is not set.

Define editUrls in the asset package:

Create a new view.tsx under lowcode/xx/:

Then run:

npm run lowcode:build

After that, build/lowcode will contain view.js, which you can configure as editUrls in the asset package.
