v2.4.2

• Improved ESM TypeScript types.
• More precise TypeScript replacer type.

v2.3.0

• Accept the Error constructor as circularValue option to throw on circular references as the regular JSON.stringify would:

import { configure } from 'safe-stable-stringify'

const object = {}
object.circular = object;

const stringify = configure({ circularValue: TypeError })

stringify(object)
// TypeError: Converting circular structure to JSON

• Fixed escaping wrong surrogates. Only lone surrogates are now escaped.

v2.0.0

• [BREAKING] Convert BigInt to number by default instead of ignoring these values If you wish to ignore these values similar to earlier versions, just use the new bigint option and set it to false.
• [BREAKING] Support ESM
• [BREAKING] Requires ES6
• Optional BigInt support
• Deterministic behavior is now optional
• The value to indicate a circular structure is now adjustable
• Significantly faster TypedArray stringification
• Smaller Codebase
• Removed stateful indentation to guarantee side-effect freeness
