Answer 1

The original library does not enable ivy by default and no one knows whether they change it in the near future.

You can use @bugsplat/angular-tree-component which is a fork of angular-tree-component which was original an upgrade to Angular 13, but it seems to work fine with 16 as well.

https://www.npmjs.com/package/@bugsplat/angular-tree-component

The other option is this one: https://www.npmjs.com/package/@ali-hm/angular-tree-component

Answer 2

Angular v16 has dropped the support for non-ivy libraries.

This library choose to not enable ivy by default.

So you won't be able to use it in a v16 project !
