Signal store not see feature requirements

[frenzymind]

Which @ngrx/* package(s) are the source of the bug?

signals

Minimal reproduction of the bug/regression with instructions

stackblitz

When I specify type in my withCRUD feature the error occurs of incorrect type, that there is no _http property in store. If ignore the error, in main.ts file no error and type of create function changed correctly.

During creation this issue I suddenly found if move withState after withCRUD - all works fine. I understand order is matter, but I give required prop before. So, any extra field will fall into error?

if I declare extra requirement in withCRUD, for example: state: type<{ foo: number }>() then I have to specify withState({ foo: 42, }) first, then withCRUD and just after this step I can to declare other state fields I need. Otherwise there is always be an error.
I always think I have to present all required fields and any extra are welcome, like with ts interfaces. I was wrong?

This is expected ?

Thanks for you time!

I'll take a closer look if this is something we can fix on the SignalStore side or if it's a TypeScript limitation. In the meantime, you can provide the entity type by using the type<>() helper function. Here is the workaround: https://stackblitz.com/edit/github-zizimitu-ljnae5fr?file=src%2FwithCRUD.feature.ts

In general, custom features with input should be used only when needed to avoid overcomplication. Instead, independent features should be preferred, or you can use withFeature.

• Option 1 - HttpClient can be injected directly inside the custom feature: https://stackblitz.com/edit/github-zizimitu-d277cmrt?file=src%2FwithCRUD.feature.ts
• Option 2 - Use withFeature: https://stackblitz.com/edit/github-zizimitu-fkv5drbr?file=src%2FwithCRUD.feature.ts

I try options 1 and 2, but I think inputs are better, but if you say

Instead, independent features should be preferred

so, no problem I can change my mind and use these options. It is totally solve my issue.
