After upgrading my project from Angular 8 to Angular 9, I encountered a warning when trying to build the library:
The '__read' is imported from external module 'tslib', but never usedhttps://i.stack.imgur.com/Xg4Eu.png
This warning was not present in Angular 8. Despite efforts to identify the cause, I have been unable to find a solution. A related issue on Github here does not provide a fix or workaround.
Your assistance with this issue would be greatly appreciated.
Have you incorporated the spread operator (...) into your project lately?
It seems that the webpack build configuration utilized by Angular CLI in version 9 is importing this functionality from tslib, yet not actually utilizing it. It's possible that in future updates, they will eliminate this superfluous import.
