I love the way the @rematch/loading plugin keeps my app's loading state all in one place. Something that stuck out to me as odd was that there's no similar plugin for handling error/success state. So I can now avoid writing a { loading, error, success } object for every reducer, but error and success are still required if I want to perform some action after the effect finishes, so the ret

Navigator 2.0 and Router have been released and are now the recommended approach:

When using the *ngrxLet structural directive in an app, the view is cleared as soon as ngOnDestroy() is called. This causes an issue with animations: the view that is animated out changes as all ngrxLet templates get cleared.

To illustrate the problem see this StackBlitz, compare the ngIf behavior with ngrxLet: https://stackblitz.com/edit/ngrx-bug-ngrxlet

I believe the problem could be fixed

When I use removeItem state operator then TypeScript complains that message object can be possibly undefined even though I specified the type for removeItem operator. I could fix the issue with optional chaining but that is not possible if I want to use a utility library like Ramda

Hello, I'm trying to type my application which is using redux-orm. I came across an issue with the new createSelector API. My code is as simple as:

import { createSelector } from 'redux-orm'
import orm from 'features/regulation/orm'

export const selectTest = createSelector(orm.Policy)

The error I get is that

Expected 2-9 arguments, but got 1.ts(2554)

I have a very big app and do not want to make a placeholder for each screen I would like to provide context to about what is loading. (And also do not want a general 'loading' message). Is there currently a way to change the title/subtitle easily for each ViewController, from the ViewController itself?

This needs to be done for:

• mobx
• flutter_mobx
• mobx_codegen

I would love to have native examples of all the state systems in https://snack.expo.io/

This is a bit of a haul, help needed.
