[chuma2150]

When installing packages with latest angular v13, a warning is popping up: Processing legacy "View Engine" libraries:

• angular-plotly.js [module/esm2015] () Encourage the library authors to publish an Ivy distribution. Thea reason for this is: https://blog.angular.io/angular-v13-is-now-available-cce66f7bc296 Refer to point "State of View Engine"

I am also getting the following warning among others while compiling:

$ ng build -c demo
⠙ Generating browser application bundles (phase: setup)...Processing legacy "View Engine" libraries:

✔ Browser application bundle generation complete.
✔ Copying assets complete.
✔ Index html generation complete.

Any progress so far ? Same here.

Getting this error:

export declare class PlotlyViaCDNModule {
                           ~~~~~~~~~~~~~~~~~~
    This likely means that the library (angular-plotly.js) which declares PlotlyViaCDNModule has not been processed correctly by ngcc, or is not compatible with Angular Ivy. Check if a newer version of the library is available, and update if so. Also consider checking with the library's authors to see if the library is expected to be compatible with Ivy.

This is getting urgent as Angular will remove the Angular Compatibility Compiler (ngcc) in version 16:

https://github.com/angular/angular/pull/49101

Anything I can do to help the process along?
