NativeScript Importing NGXS module in app.module throw an error in log console

Question

I'm new with NativeScript and I want to use a state management NGXS and implement to my app. I have installed NGXS with NPM: @ngxs/store @ngxs/logger-plugin and @ngxs/devtools-plugin.

So I added those NGXS module to my app.module.

import { NgModule, NO_ERRORS_SCHEMA } from "@angular/core";
import { NativeScriptModule } from "nativescript-angular/nativescript.module";
import { NativeScriptUISideDrawerModule } from "nativescript-ui-sidedrawer/angular";

import { NgxsModule } from '@ngxs/store';
import { NgxsLoggerPluginModule } from '@ngxs/logger-plugin';
import { NgxsReduxDevtoolsPluginModule } from '@ngxs/devtools-plugin';

import { AppRoutingModule } from "./app-routing.module";
import { AppComponent } from "./app.component";
import { PetState } from './_ngxs/pet/pet.state';

@NgModule({
  bootstrap: [
    AppComponent
  ],
  imports: [
    AppRoutingModule,
    NativeScriptModule,
    NativeScriptUISideDrawerModule,
    NgxsModule.forRoot([
        //if i uncomment PetState, in console log show me error, Failed to find module: "./pet.actions"
        // PetState
    ]),
    //if i uncomment `NgxsLoggerPluginModule.forRoot()`, in console log show me error, Failed to find module: "@ngxs/logger-plugin
    // NgxsLoggerPluginModule.forRoot(),
    //if i uncomment `NgxsReduxDevtoolsPluginModule.forRoot()`, in console log show me error, Failed to find module: "@ngxs/devstool-plugin
    // NgxsReduxDevtoolsPluginModule.forRoot() 
  ],
  declarations: [
    AppComponent
  ],
  schemas: [
    NO_ERRORS_SCHEMA
  ]
})
export class AppModule { }

After I added the ngxs module, I got 2 issues.

1. under NgxsModule.forRoot if I uncomment PetState it throw me error in console log, Failed to find module: "./pet.actions". Please refer

2. If I uncomment NgxsLoggerPluginModule.forRoot() / NgxsReduxDevtoolsPluginModule.forRoot() I will get error in console log and saying failed to find module @ngxs/logger-plugin / @ngxs/devstool-plugin

below is pet.state.ts codes

import { State, Action, Selector, StateContext } from '@ngxs/store';
import { Pet } from './pet.model';
import { AddPet, RemovePet } from './pet.actions';

export class PetStateModel {
  pets: Pet[];
}

@State<PetStateModel>({
  name: 'Pet',
  defaults: {
    pets: []
  }
})

export class PetState {

  @Selector()
  static getPet(state: PetStateModel) {
    return state.pets;
  }

  @Action(AddPet)
  addPet({getState, patchState}: StateContext<PetStateModel>, { payload }: AddPet) {
    const state = getState();
    patchState({
        pets: [...state.pets, payload]
    })
  }

  @Action(RemovePet)
  removePet({getState, patchState}: StateContext<PetStateModel>, { payload }: RemovePet) {
    const state = getState();
    patchState({
        pets: state.pets.filter(a => a.name !== payload )
    })
  }
}

I really need someone can give some hand to help me fix the issues, thanks,

Answer 1

Ok I found the solution. After few hours I found this solution here and with my solutions

Just need to remove node_modules, hook and platform folder then npm i and add the platform for both ios and android.

and 1 more thing I am not sure why, I uninstalled for @ngxs/logger-plugin and @ngxs/devtools-plugin and reinstall back to the dependency not in dev dependency.

anyway, for now it work for me.
