JSON.stringify doesn't work in circulative JSON object. What to do?

Question

e.g., in Node.js, if I do this:

JSON.stringify(req);

Then I will fail because of circulative structure.

is there any setting or way to stringify it easily and skip the circulative part of structure?

Is it possible to have a circulative structure in JSON? I thought Crockford did a talk where he explicitly said those couldn't be done. — sdleihssirhc

if you can serialize the object, than you can stringify it. If object can't be serialized than it can't be stringify. — Gagandeep Singh

It is possible. Default req object in node.js or any DOM object contains circulative structure. how to serialize the object? — murvinlai

You might be confusing JSON with JavaScript objects. JSON is a subset of JavaScript. Native objects can do things that JSON can't. — sdleihssirhc

Crockford's library (see cycle.js) https://github.com/douglascrockford/JSON-js supports encoding and decoding of circular objects into json (+ jsonpath).
