Unable to get latest state value using ngrx in Angular

Question

Hello guys I am new to angular. These days I am trying to learn state management in angular. well, I tried following some tutorials but some of their code was already depreciated so I am a bit stuck in a problem. I am unable to get the latest state value in my ts file even after subscribing to it.

//Action File
import { Action } from '@ngrx/store';

export enum CategoriesActionTypes {
  LoadCategoriess = '[Categories] Load Categoriess',
  LoadCategoriessSuccess = '[Categories] Load Categoriess Success',
  LoadCategoriessFailure = '[Categories] Load Categoriess Failure',
}

export class LoadCategoriess implements Action {
  readonly type = CategoriesActionTypes.LoadCategoriess;
}

export class LoadCategoriessSuccess implements Action {
  readonly type = CategoriesActionTypes.LoadCategoriessSuccess;
  constructor(public payload: { data: any }) { }
}

export class LoadCategoriessFailure implements Action {
  readonly type = CategoriesActionTypes.LoadCategoriessFailure;
  constructor(public payload: { error: any }) { }
}

export type CategoriesActions = LoadCategoriess | LoadCategoriessSuccess | LoadCategoriessFailure;

//Reducer file

import { CategoriesActions, CategoriesActionTypes } from '../Actions/categories.actions';
import { Action } from '@ngrx/store';


export const categoriesFeatureKey = 'categoriesState';

export interface State {
categories :any,
error: any
}

export const initialState: State = {
  categories:[{name:'name'}],
  error :null,
};

export function reducer(state = initialState, action: CategoriesActions): State {
  
  switch (action.type) {
    case CategoriesActionTypes.LoadCategoriess:
    return{
      ...state
    }
    case CategoriesActionTypes.LoadCategoriessSuccess:
      // debugger
      console.log(action.payload.data);
      
      return {
        ...state,
        categories: action.payload.data,
        error: ''
      }

    case CategoriesActionTypes.LoadCategoriessFailure:
      return {
        ...state,
        categories: [],
        error: action.payload.error
      }
    default:
      return state;
  }
}

//Effects File

import { FrontserveiceService } from './../front/frontserveice.service';
import { Injectable } from '@angular/core';
import { Actions, Effect, createEffect, ofType } from '@ngrx/effects';

import { Observable, of } from 'rxjs';
import { Action } from '@ngrx/store';
import * as CategoriesActions from './../Actions/categories.actions';
import { mergeMap, map, catchError } from 'rxjs/operators';

@Injectable()
export class CategoriesEffects {



  constructor(private actions$: Actions,private service:FrontserveiceService) {}


  // @Effect()
  loadCategories$: Observable<any> = createEffect(() =>
  this.actions$.pipe(
    ofType(CategoriesActions.CategoriesActionTypes.LoadCategoriess),
    mergeMap(
      action => this.service.CategoryList({ image: true }).pipe(
        map(users => {
          return (new CategoriesActions.LoadCategoriessSuccess({ data: users }));
        }),
        catchError(err => of(new CategoriesActions.LoadCategoriessFailure({ error: err })))
      )
    )
  ));
  
}

I hope someone can guide me. My angular version is 10.2.

EDITED Subscription

this.store.dispatch(new CategoriesActions.LoadCategoriess());
    // console.log(select(fromcategory.getUsers));
    
    this.store.pipe(select(fromcategory.getUsers)).subscribe(
      users => {
        console.log(users);
        this.categories = users.categories;
        this.service.CategoryData = users.categories != undefined ? users.categories : [];
        this.Scategory = this.StoreSelect(this.categories);

      }
    )
    this.store.pipe(select(fromcategory.getError)).subscribe(
      err => {
        console.log(err);
      }
    )

Redux Devtools

//Selector

import { State } from './../Reducerss/categories.reducer';
import { createFeatureSelector, createSelector } from '@ngrx/store';

const getCategoryFeatureState = createFeatureSelector<State>('categoriesState');

export const getUsers = createSelector(
    getCategoryFeatureState,
    state => state.categories
)

export const getError = createSelector(
    getCategoryFeatureState,
    state => state.error
)

Answer 1

I got it now. I was trying to access a portion of the state which is not allowed that's why I was unable to access the state in the subscription.
