Upgrading from version 2.0.1 to 2.1.0 or 2.2.0 breaks vite build with TS (TS7006) errors

[acostaf]

Hi Team

I just upgraded to version 2.2.0 and the change creates those this really weird issue, I am not changing anything on my tsconfig and eslinyrc and suddenly running vite build throws more than 600 implicit any type

Have anyone seen these before?

[EskiMojo14]

could you give an example of a piece of code which now errors?

[acostaf]

const user = useAppSelector(selectedUser)

user?.uid used to work properly not errors but now the new versions says that user is any but the selector was created from a proper type.

[acostaf]

Funny enough the selector is now returning unknown, which force the error on build

[EskiMojo14]

any chance you could put together a reproduction in typescript playground, codesandbox or a repo? none of our tests broke 😕

[acostaf]

Actually I think the issue is coming from createDrafSafeSelector the function does not detect the original type returning any or unknown

[EskiMojo14]

could you show how you're using it?

[acostaf]

Sorry about no been able to provide a proper example, I am behind a proxy so cannot copy and paste the real code.

store/Index.ts

const selectOriginalThing = (state: Rootstate) => state.myState.thing; (thing is properly typed as Type? from slice)

export const selectThing = createDraftSafeSelector(selectOriginalThing, (thing) (here is the type error, thing is now “any” instead of inferring type from selectOriginalThing

[EskiMojo14]

seems to be working in a playground - what typescript version are you using?

[acostaf]

5.3.3

[EskiMojo14]

not sure what to suggest at this point then, sorry - without a replication i can't really look into it further

I had the same issue, I removed the package and then deleted node_modules, after which I installed the package again and it worked

The problem is probably that you have a store slice which use a strongly typed app-specific dispatch.
To create a type for that app-specific dispatch, you need the fully constructed store.
To craete the fully constructed store, you need all the slices.
To make that one slice, you need the app-specific dispatch.

Things tend to become, literally, a bit loopy in those type of scenarios unless you very, very carefully order your imports in meticulous ways and ensure that type-only references are imported with import type.

I had a similar error

node_modules/@reduxjs/toolkit/dist/createDraftSafeSelector.d.ts:10:47 - error TS2707: Generic type 'CreateSelectorFunction<MemoizeFunction, ArgsMemoizeFunction>' requires between 0 and 2 type arguments.

10 export declare const createDraftSafeSelector: import("reselect").CreateSelectorFunction<typeof weakMapMemoize, typeof weakMapMemoize, any>;

and was able to fix it by updating the reselect dependency (from v5.0.1 to 5.1.0 in my case).

Similar to @AlbericoD I just removed and re-added rtk...

yarn remove @reduxjs/toolkit
yarn add @reduxjs/toolkit

I think the issue here is that the new createDraftSafeSelector.withTypes() is derived from createSelector.withTypes() which is a feature that was added in reselect v5.1.0 but reselect is listed as a dependency of RTK with the version of ^5.0.1 so if the installed version of reselect is 5.0.1 and not 5.1.0 we get this type error and it goes away once we bump reselect to 5.1.0. I think we might have to update the dependency version of reselect to 5.1.0 in RTK since the .withTypes() feature of createDraftSafeSelector comes directly from reselect v5.1.0. @EskiMojo14 I can put up a PR to fix it tomorrow if you want.
