💻 Code

import ZodRoute from "zod-route-schemas";
import z from "zod";

export const organization = new ZodRoute(
  "/org/:organizationId",
  z.object({ organizationId: z.number() }),
);

🙁 Actual behavior

    4 export const organization = new ZodRoute(
                   ~~~~~~~~~~~~

I don't see what the problem is here, because as you can see below, the generated .d.ts would have the private field types from the class declaration in zod-route-schemas.

🙂 Expected behavior

Outputs the following .d.ts like TS5/6:

import ZodRoute from "zod-route-schemas";
import z from "zod";
export declare const organization: ZodRoute<"/org/:organizationId", z.ZodObject<{
    organizationId: z.ZodNumber;
}, "strip", z.ZodTypeAny, {
    organizationId: number;
}, {
    organizationId: number;
}>, z.ZodType<{
    organizationId: number;
}, any, {
    organizationId: number;
}>, z.ZodType<{
    organizationId: number;
}, any, {
    organizationId: number;
}>>;
//# sourceMappingURL=index.d.ts.map

Additional information about the issue

Doesn't happen with "module": "preserve", but happens with "commonjs", "nodenext", maybe others

ZodRoute declaration in zod-route-schemas/index.d.ts:

declare class ZodRoute<Pattern extends string, Schema extends SchemaForPattern<Pattern>, FormatSchema extends InvertSchema<Schema> = InvertSchema<Schema>, PartialFormatSchema extends PartialSchema<FormatSchema> = PartialSchema<FormatSchema>> {
  readonly pattern: Pattern;
  readonly schema: Schema;
  private parts;
  readonly formatSchema: FormatSchema;
  readonly partialFormatSchema: PartialFormatSchema;
  readonly exact: boolean;
  private typeHints?;
