How can I print a circular structure in a JSON-like format?

The Solution to How can I print a circular structure in a JSON-like format? is


In Node.js, you can use util.inspect(object). It automatically replaces circular links with "[Circular]".


Albeit being built-in (no installation is required), you must import it

import * as util from 'util' // has no default export
import { inspect } from 'util' // or directly
// or 
var util = require('util')
To use it, simply call
console.log(util.inspect(myObject))

Also be aware that you can pass options object to inspect (see link above)

inspect(myObject[, options: {showHidden, depth, colors, showProxy, ...moreOptions}])
