Types not resolving correctly after 2.9.2 about json-schema-to-ts

[ThomasAribart]

Hi @hamanuha and thanks for reaching out!

This seems to be related to #165, you can look at https://github.com/ThomasAribart/json-schema-to-ts/blob/main/documentation/FAQs/applying-from-schema-on-generics.md

This worked for me:

type ContractRouteImplementation<
  CONTRACT_ROUTE extends ContractRoute,
  PARAMS = FromSchema<CONTRACT_ROUTE["params"]>,
  QUERY = FromSchema<CONTRACT_ROUTE["query"]>,
> = () => {
  handler: (request: { Params: PARAMS; Query: QUERY }) => void;
};

Hi @ThomasAribart,

thanks for the hint. Unfortunately this does not work for me.
I am using typescript 5.3.3. Maybe it's related to some config values?

Would you mind sharing your tsconfig?

Edit:
When using your asConst function it works with both versions of the ContractRouteImplementation.
But only if I use as const as well.

const contract = initContract({
  demo: {
    params: asConst({
      type: 'object',
      properties: {
        str: { type: 'string' },
      },
      required: ['str'],
      additionalProperties: false,
    } as const),
    query: externSchema,
  },
})

Edit2:
When using the Narrow type from your package inside FromSchema it works also for the inline schema without having to use asConst

type ParamsFromSchema<T extends ContractRoute, TParams = Narrow<T['params']>> = TParams extends JSONSchema
  ? FromSchema<TParams>
  : never

Hey @ThomasAribart,

did you see my second edit?
Can I help with something to resolve this issue?
