Discover why you can't JSON.stringify(your_object) and automaticly remove the causes.

npm i stringify-safe

const StringifySafe = require('stringify-safe')

StringifySafe checks if JSON.stringify(your_object) fails.

With .fixStringify() the causes will be recursively determined and removed.

var fixedObject = StringifySafe.fixStringify(brokenObject)

You can manually set a maximal recusion depth. The default is 10.

0 means recursion and if your brokenObject is broken {} will be returned.

// depth = 5
var fixedObject = StringifySafe.fixStringify(brokenObject, 5)

If you want to see wich childs fail to get stringified, set printing to true. The default is false.

// depth = 6
// printing = true
var fixedObject = StringifySafe.fixStringify(brokenObject, 5 true)

This function is a warpper for .fixStringify(), but it direclty JSON.stringify(your_object) you object.

The parametrs are working like .fixStringify().

var fixedStrigifiedObject = StringifySafe.stringify(brokenObject)

This function tells you if your object is broken by returning a boolean.

var isBroken = StringifySafe.isBroken(your_object)

This function tells you if your object contains broken childs by returning a boolean.

var hasBrokenChilds = StringifySafe.hasBrokenChilds(your_object)
