Unexpected Output with JSON.stringify in Node.js - implementing Circular References
I'm having trouble with I've been struggling with this for a few days now and could really use some help..... I tried several approaches but none seem to work. I'm working with a question with the `JSON.stringify` method in Node.js when trying to serialize an object that has circular references. I'm using Node.js version 14.17.0 and my object structure looks something like this: ```javascript const objA = {}; const objB = { a: objA }; objA.b = objB; // Creating a circular reference ``` When I attempt to serialize `objA` using `JSON.stringify(objA)`, I get the behavior `TypeError: Converting circular structure to JSON`. I've already tried using a custom replacer function to handle circular references like so: ```javascript const cyclicReplacer = (key, value) => { if (value === objA) return '[Circular: objA]'; return value; }; const jsonString = JSON.stringify(objA, cyclicReplacer); ``` However, this just ends up returning `undefined` for `objB` instead of the desired output. I also looked into using libraries like `flatted` and `circular-json`, but I prefer not to add extra dependencies if possible. Is there a way to handle this serialization scenario effectively in pure Node.js, or do I have to rely on external libraries? Any guidance or best practices would be greatly appreciated! I'd really appreciate any guidance on this. I'm working on a web app that needs to handle this. Any ideas what could be causing this? The project is a REST API built with Javascript.
