Hello. Does anyone know how to hook-into the ngrx bootstrap life-cycle? I’d like to know when ngrx (state, effects, reducers) has been initialized. thoughts anyone?

Hey guys I have a problem while building project with ngrx/effects :
Error: node_modules/@ngrx/effects/src/concat_latest_from.d.ts:2:145 - error TS2574: A rest element type must be an array type. export declare function concatLatestFrom<T extends Observable<unknown>[], V>(observablesFactory: (value: V) => [...T]): OperatorFunction<V, [V, ...{ [i in keyof T]: ObservedValueOf<T[i]>; }]>;
installed : "@ngrx/effects": "11.1.1", does anybody know what is going on ?

@zoinho I am getting the same error after upgrading to rxJS 7. I had to downgrade to rxjs 6.6.3 and it started working again. Looks like the effects library will have to be updated before we can upgrade our own apps to rxJS 7.

Hi, is there a way to turn on and off StoreDevtoolsModule on runtime from initializer value or something?

@bab2683 Where you able to find the fix for pipe_1.pipeFromArray(...) is not a function?
Braulio
@bab2683
@Dixit199213bafna didn't find a solution per se, but it was caused by a misconfiguration on my store, try double-checking everything, it could be even a typo

still active community here? question about entityAdapter,
it seems like deeper object key data is overwritten completely instead of concat, what i would expect.
if this is my entity:

'93dd0fd6-fd8c-4c70-a213-cb76d1ef6eda': {
            guid: '93dd0fd6-fd8c-4c70-a213-cb76d1ef6eda',
            languageSettings: {
                DE: {
                    slug: 'velows',
                },
                EN: {
                    slug: 'velows',
                },
                FR: {
                    slug: 'velows',
                },
                NL: {
                    slug: 'veluwe',
                },
            },
        },

and i update the object with a specific language for content like

```
'93dd0fd6-fd8c-4c70-a213-cb76d1ef6eda': {
            guid: '93dd0fd6-fd8c-4c70-a213-cb76d1ef6eda',
            languageSettings: {
                EN: {
                    slug: 'velows',
                    title: 'Testing EN',
                    content: 'Test',
                },
            },
        },

How do i concat with the entityAdapter?

Hi, I am having massive issues with NGRX
https://stackoverflow.com/questions/66592750/ngrx-unrelated-select-firing-when-updates-another-slice-of-state
^ basically this exact thing is happening to me.
Unrelated selectors are firing when I change a different slice of the app state...
I don't see anywhere that I can put "distinctUntilChanged" with the "new" ngrx syntax... 🤔
export const selectConnectedAccount = (state: AppState) => state.login
  ngOnInit() {

    this.store
      .pipe(
        map(state => {
          console.log('mapping state header: ', state)
          return selectConnectedAccount(state);          
        }),
        filter(val => val !== undefined),
        filter((val: any) => val.currentAccount !== undefined),
        // distinctUntilChanged
        )
        .subscribe(
          state => {
            if (state.currentAccount) {

              console.log('got new connected address: ', state)
              this.connectedAddress = state.currentAccount;


              // Uncommenting below line causes infinite loop of ngrx actions firing...
              // this.store.dispatch(loadHydrants({ account: this.connectedAddress }))
              console.log('got address, dispatching call for hydrants... ', this.connectedAddress)
            }
            else 
              console.log('got empty state: ', state)
        }
      )
  }
export interface AppState {
    login: any;
    hydrants: any;
}

^ can anyone see what's wrong with this code?
Jim Lynch
@JimLynchCodes
Seems like I was using a wrong selecting syntax (for 9.2.1 ngrx, at least).
It's working for me with this syntax:
this.store.select(state => selectLoginState(state))
      .subscribe(
        state => {

            console.log('got some state stuff: ', state)

        }
)

@bab2683 I was able to find the fix the change that is required to fix error for pipe_1.pipeFromArray(...) and that is replace this.store.pipe(select(getValue)) -> this.store.select(getValue)

i'm using angular 12 + ngrx 12.2 + router-store. i have a ItemListComponent that shows a list of items and ItemDetailsComponent that shows details about one item. if i go to the list component and get the list of all items and then from there router.navigate to the Details component e.g. /itemDetails/1 everything works fine using <div *ngIf="item$ | async as item" however, if i navigate directly to the /itemDetails/1 the item details don't show up. in my facade, i have

    selectedItems$ = this.store
        .pipe(select(ItemsSelectors.getSelected))
        .pipe(
            tap(project => {
                if (!project) {
                    this.loadAllItems();
                }
            }),
            filter(project => {
                console.log('item: ', item);
                return item !== undefined;
            })
        );

i can see it logging the empty item before it pulls the list and the item with data after

@syndesis it has been quite a while I used router-store, but I could remember that there seemed to be a race condition between the declaration of the effects, and the router events. Basically I was missing actions because the ROUTER events were not caught by the effects on navigating directly to the components as the effects were not loaded at that time. it was about 3 or 4 years ago though, this might have changed, but I would look into this if I were you
Frank Sheiness
@syndesis
i discovered that if i wrap my component in an outer component that uses the store variable | async as Input it works
i don't know why that's different from an outer div on the original component, though

hi guys any example for authentification model with spring boot +angular (ngrx)
Mark
@bhalash
Just wondering if there is a good way forward for using factory selectors with MockStore#overrideSelector, not that props are deprecated. I cannot seem to find a good fit that works
There exists plenty of documentation to migrate the selector itself, but nothing clear. If anyone has a path I'm quite happy to throw up a docfix PR :)

Hi guys, does ngrx/data worth to use it instead of ngrx?
Matt Erman
@CodeLiftSleep
@alexandrupintilei Yse....using both data and entities have streamlined everything for us...no actions, reducers, effects or anything else...it just works by looking for the properly named API...it's amazing and has reduced the numbe of lines of code tremendously
if you need to do something customized you can still use all of those things, but you shouldn't need to in most cases
BertrandMarechal
@BertrandMarechal
@CodeLiftSleep is it easy to teach newcomers on the app ?
Matt Erman
@CodeLiftSleep
Highly, highly recommend it...basicaly its like an ORM for the front end
It isn't hard...angular university has a great course on it..I would recommend taking that
basically if you have an entity names car, if you make a getAll call, the API would look for an endpoint named cars
if you are using getById() it would look for an endpoint named car
etc
and it basicaly just works like magic
Alex
@alexandrupintilei
@BertrandMarechal @CodeLiftSleep this guy explain very well how it works:
https://www.youtube.com/watch?v=TenetyDn4XM&ab_channel=ApplicableProgramming
consider ngrx/data can you have different slice for each enitity? if you need lets say slice1 state into slice2, can you access it?
Alex
@alexandrupintilei
@CodeLiftSleep do i need ngrx entity if i will use data?
as i understood ngrx data does not neet reducer, effects etc in order to store data

@tzamora
every time we subscribe to an selector, the current value is emited inmediately after subscription, is there a way to subscribe to a selector but only get the subsequent emitions after the subscription not the current value?
I need to subscribe to a selector observable but only get the values AFTER the subscription. Thanks

I'm using ngrx/data -- what is the best-practice for displaying errors to the user in a HTTP request failed scenario? Does ngrx offer anything out of the box?

hi! Is there anything prohibiting us from adding the ngrx forRoot into a module other than app.module? I am aware and have worked extensively with feature states but need to see if forRoot store can be moved into another lazyloaded module instead of app.module.ts. thoughts?
