Simple, stupid zod FormData validation

zod-form-data.ts

import { z } from 'zod';

// If you feel zod-form-data is too bulky for what 
// you're trying to do, try this:
export const zfd = <T extends z.ZodRawShape>(shape: T) => {
  return z.custom<FormData>().transform(
    (fd) => Object.fromEntries(
      fd.entries() as IterableIterator<[string, string]>
    )
  ).pipe(z.object(shape));
}

const schema = zfd({
  username: z.string().min(3),
  email: z.string().email(),
  age: z.coerce.number(),
})

const formData = // get your FormData from somewhere

const {
  username,
  email,
  age,
} = schema.parse(formData);
