How get a state in feature module?

this.todos$ = this.store.select(state => state.todos.data)

I use this tutorial but I cannot understand what is fromStore

Answer 1

if your reducer.ts export that

export function myList(state = [], action: Action) {
switch (action.type) {
    case 1:
        return data1;
    case 2:
        return data2;
    default:
        return state;
 }
}

your store.model.ts must be this:

 export interface AppStore {
     myList: element[];
     ...
 }

and you can get the state like this :

constructor(private store: Store<AppStore>) {}

this.todos$ = this.store.select("myList")

that will return an Observable of elements array
