Getting started

Unsubscribe helper: UnsubscriptionHandler

import { UnsubscriptionHandler } from 'arxjs';
import {select, Store} from '@ngrx/store';
import {ActivatedRoute} from '@angular/router';
import {takeUntil} from 'rxjs/operators';

export class UsersComponent extends UnsubscriptionHandler {
 constructor(
    protected store: Store<any>,
    protected route: ActivatedRoute, 
   ) {
    super();
 }

 // Subscribe any type of stream and use this.unsubscribe$ to unsubscribe them. 
 test() {
    this.store.pipe(select(fromStore.getUsers), takeUntil(this.unsubscribe$)).subscribe(data => {
      ...
    });

    this.route.paramMap.pipe(takeUntil(this.unsubscribe$)).subscribe(params => {
      ...
    });
 }
}

NgRx action helpers: Action & Action Payload

import {UserInterface} from './interfaces/user.interface';
import { Action, PayloadAction } from 'arxjs';

export const LOAD_USERS = '[Admin] LOAD_USERS';
export const LOAD_USERS_SUCCESS = '[Admin] LOAD_USERS_SUCCESS';
export const LOAD_USERS_FAIL = '[Admin] LOAD_USERS_FAIL';

export class LoadUsers implements Action {
  readonly type = LOAD_USERS;
}

export class LoadUsersSuccess extends PayloadAction<UsersInterface[]> {
  readonly type = LOAD_USERS_SUCCESS;
}

export class LoadUsersFail extends PayloadAction<any> {
  readonly type = LOAD_USERS_FAIL;
}

export type AdminAction = LoadUsers
  | LoadUsersSuccess
  | LoadUsersFail;

So instead of writing

export class LoadUsersSuccess implemant Action {
  readonly type = ADMIN_USER_LIST_SUCCESS;
  constructor(public payload: UsersInterface[]) {}
}

export class LoadUsersFail implemant Action {
  readonly type = LOAD_USERS_FAIL;
  constructor(public payload: any) {}
}

Use PayloadAction class

export class AdminUserListSuccess extends PayloadAction<UsersInterface[]> {
  readonly type = ADMIN_USER_LIST_SUCCESS;
}

export class LoadUsersFail extends PayloadAction<any> {
  readonly type = LOAD_USERS_FAIL;
}
