An Nx plugin & Angular module set that allows you to build documentation applications natively in Angular! This project has a focus on documenting Angular components (e.g. component library), but it can be used for any documentation needs you might have in Angular.
Rxjs not being a peer dependency here https://github.com/OasisDigital/ng-doc-portal/blob/main/libs/ng-doc-portal-plugin/package.json. Need to add it similar to what Angular does here https://github.com/angular/angular/blob/main/packages/core/package.json so that there can be overrides for repos that have multiple versions.
