z.object().coerce() please? Same as z.object().partial() or .required(), making some or all properties "coerced"

[sebastienbarre]

Given a schema, I'm trying to get the equivalent schema where specific fields are now z.coerce....

const Recipe = z.object({
  title: z.string(),
  createdAt: z.date(),
});

then

const RecipeCoercedDate = Recipe.coerce({
  createdAt: true,
});

would return:

z.object({
  title: z.string(),
  createdAt: z.coerce.date(),
});

Not going to lie, I’m a TypeScript and Zod newbie, so I asked an AI for help (sorry), and the resulting function was so massive it pretty much confirmed this is non-trivial. I’d really prefer to get some human input on how to implement this.

Thank you
