Chrome sendrequest error: TypeError: Converting circular structure to JSON

Question

I\'ve got the following...

chrome.extension.sendRequest({
  req: \"getDocument\",
  docu: pagedoc,
  name: \'name\'
}, function(response){
  var efjs = respo         


        

Answer 1

I normally use the circular-json npm package to solve this.

// Felix Kling's example
var a = {};
a.b = a;
// load circular-json module
var CircularJSON = require('circular-json');
console.log(CircularJSON.stringify(a));
//result
{"b":"~"}

Note: circular-json has been deprecated, I now use flatted (from the creator of CircularJSON):

// ESM
import {parse, stringify} from 'flatted/esm';

// CJS
const {parse, stringify} = require('flatted/cjs');

const a = [{}];
a[0].a = a;
a.push(a);

stringify(a); // [["1","0"],{"a":"0"}]
