Utilizing Angular 7, Ngrx, and Rxjs 6 to efficiently share state data among lazily loaded modules

Currently, I am working with Angular 7 alongside Ngrx and Rxjs 6. In my project, I have two lazy loaded modules named A and B, each with its own selectors and reducers.

The challenge I am facing is accessing the data stored in module B's state from module A. Due to the nature of lazy loading, the components of module B are only initialized when the user navigates to that specific route. This leads to undefined errors if I try to select the state while on module A.

What would be the recommended approach for accessing the state of a lazy loaded module in this scenario?

Answer №1

From my perspective, his particular scenario is legitimate and ngrx should have the capability to accommodate it. However, there seems to be an issue with state dropping if a reducer is not included in ngrx via the forFeature function. This problem arises when dealing with lazy loaded modules that have not been fully loaded yet, thereby hindering the retrieval of the entire state from a backend database for usage in these specific modules.
