State management refers to the management of the state of one or more user interface controls such as text fields, submit buttons, radio buttons, etc.
As applications grow, this can end up becoming one of the most complex development problems.
For the Angular framework there exist multiple community options: NgRx (based on Redux, with a lightweight alternative using Signals), NGXS and RxAngular.
As the documentation in Redux alludes, many of these state management libraries are lightweight and can be replaced by each other.
