zod-form-data/dist/index.mjs

Validation helpers for [zod](https://github.com/colinhacks/zod) specifically for parsing `FormData` or `URLSearchParams`. This is particularly useful when using [Remix](https://github.com/remix-run/remix) and combos well with [remix-validated-form](https:

var __defProp = Object.defineProperty;
var __export = (target, all) => {
  for (var name in all)
    __defProp(target, name, { get: all[name], enumerable: true });
