Issue with inferring types from pipes. about zod HOT 6 CLOSED

I'd recommend checking out this guide for some pointers on writing generic functions that accept Zod schemas: https://github.com/colinhacks/zod?tab=readme-ov-file#writing-generic-functions

from zod.

Thanks @colinhacks, although having to infer the return type of a generic parsing function feels a bit icky. Wonder if there is a way to avoid that

from zod.

As it means that we're actually short circuiting the return type when we return the value of schema.parse, which could lead to human error that is not caught by TS

from zod.

I have found that

const parseSchema = <Input, Output>(
  data: any,
  schema: z.ZodType<Output, ZodTypeDef, Input>,
): Output => {
  return schema.parse(data)
}

Fixes this without having to resort into type casting.

This is the recommended way to write that function:

// parse any data into schema or fail
const parseSchema = <U extends z.ZodType>(data: any, schema: U): z.infer<U> => {
  return schema.parse(data);
};

from zod.

This is the recommended way to write that function:

// parse any data into schema or fail
const parseSchema = <U extends z.ZodType>(data: any, schema: U): z.infer<U> => {
  return schema.parse(data);
};

Can I ask why is that recommended over what I've done? Just for my understanding
