Cyclical objects

Despite supporting recursive schemas, passing cyclical data into Zod will cause an infinite loop in some cases.

You can protect against cyclical objects starting an infinite loop (at a performance cost) with the following approach (using the above jsonSchema as an example):

Better local require() paths for Node.js

Problem

When the directory structure of your Node.js application (not library!) has some depth, you end up with a lot of annoying relative paths in your require calls like:

const Article = require('../../../../app/models/article');

Those suck for maintenance and they're ugly.

Possible solutions

Node.js core does its best to treat every platform equally. Even if most Node developers use OS X day to day, some use Windows, and most everyone deploys to Linux or Solaris. So it's important to keep your code portable between platforms, whether you're writing a library or an application.

Predictably, most cross-platform issues come from Windows. Things just work differently there! But if you're careful, and follow some simple best practices, your code can run just as well on Windows systems.

Paths and URLs

On Windows, paths are constructed with backslashes instead of forward slashes. So if you do your directory manipulation
