You can pass a parser function to return your own custom type

import { createEnv } from 'typed-env';

const env = createEnv({
HOMEPAGE: { parser: url => new URL(url) }
});

env.HOMEPAGE; // URL

If you want to use a custom env, pass env in the options parameter, otherwise it will load from process.env

`ts
interface Options {
env?: Record | NodeJS.ProcessEnv;
}
