BREAKING CHANGES

• component: ReactiveComponentModule is removed in favor of LetModule and PushModule.

BEFORE:

import { ReactiveComponentModule } from '@ngrx/component';

@NgModule({
  imports: [
    // ... other imports
    ReactiveComponentModule,
  ],
})
export class MyFeatureModule {}

AFTER:

import { LetModule, PushModule } from '@ngrx/component';

@NgModule({
  imports: [
    // ... other imports
    LetModule,
    PushModule,
  ],
})
export class MyFeatureModule {}

• store: The projector method has become strict

BEFORE:

You could pass any arguments to the projector method

const selector = createSelector( selectString, // returning a string selectNumber, // returning a number (s, n, prefix: string) => { return prefix + s.repeat(n); } )

// you could pass any argument selector.projector(1, 'a', true);

AFTER:

const selector = createSelector( selectString, // returning a string selectNumber, // returning a number (s, n, prefix: string) => { return prefix + s.repeat(n); } )

// this throws selector.projector(1, 'a', true); // this does not throw because the arguments have the correct type selector.projector(1, 'a', 'prefix');

• store: The projector function on the selector is type-safe by default.

BEFORE:

The projector is not type-safe by default, allowing for potential mismatch types in the projector function.

const mySelector = createSelector(
  () => 'one',
  () => 2,
  (one, two) => 3
);

mySelector.projector(); // <- type is projector(...args: any[]): number

AFTER:

The projector is strict by default, but can be bypassed with an any generic parameter.

const mySelector = createSelector(
  () => 'one',
  () => 2,
  (one, two) => 3
);

mySelector.projector(); // <- Results in type error. Type is projector(s1: string, s2: number): number

To retain previous behavior

const mySelector = createSelector(
  () => 'one',
  () => 2,
  (one, two) => 3
)(mySelector.projector as any)();

• effects: The @Effect decorator is removed

BEFORE:

Defining an effect is done with @Effect

@Effect() data$ = this.actions$.pipe();

AFTER:

Defining an effect is done with createEffect

data$ = createEffect(() => this.actions$.pipe());

• effects: The signature of provideEffects is changed to expect a spreaded array of effects.

BEFORE:

provideEffects expecteded the effects to be passed as an array.

// single effect
provideEffects([MyEffect])

// multiple effects
provideEffects([MyEffect, MySecondEffect])
```ts

AFTER:

`provideEffects` expects the effects as a spreaded array as argument.

```ts
// single effect
provideEffects(MyEffect)

// multiple effects
provideEffects(MyEffect, MySecondEffect)
```ts
