19.1 triggers angular import warning: swimlane-ngx-charts.js depends on 'clone-deep'. CommonJS or AMD dependencies can cause optimization bailouts.

Describe the bug

Warning: C:\temp\updatecheck\node_modules\@swimlane\ngx-charts\__ivy_ngcc__\fesm2015\swimlane-ngx-charts.js depends on 'clone-deep'. CommonJS or AMD dependencies can cause optimization bailouts.

in a new angular cli app using ngx-charts 19.1.0

For more info see: https://angular.io/guide/build#configuring-commonjs-dependencies To Reproduce Steps to reproduce the behavior:

1. ng new a temp app
2. script (note: npm installs other than ngx-charts here are undocumented dependencies necessary to fix build errors):

   cd updatecheck
   npm i @angular/cdk --save
   npm i @swimlanes/ngx-charts --save
   npm i @types/d3 --save-dev
   

3. add NgxChartsModule to AppModule
4. put <ngx-charts-legend></ngx-charts-legend> in app.component.html
5. run ng serve

Expected behavior

app builds without warnings

ngx-charts version

19.1.0

Additional context Add any other context about the problem here.

The clone-deep package is only used in one spot where is it completely unnecessary. It looks like clone-deep was not even added as a dependency. It is in node_modules only because of:

Hoisted from “@angular-devkit#build-angular#webpack-merge#clone-deep”

The warning should not be ignored, the usage should be removed.

Agreed - usage should be removed if at all possible
