Properly update an error's stack.

In V8 (Chrome, Node.js, Deno, etc.), error.stack includes error.message. However, if error.stack is modified, error.message is not updated accordingly. This library fixes it.

In other JavaScript engines, this library just sets error.stack.

Without set-error-stack:

const error = new Error('one')
console.log(error.stack) // 'Error: one ...'
console.log(error.message) // 'one'

error.stack = error.stack.replace('one', 'two')
console.log(error.stack) // 'Error: two ...'
console.log(error.message) // 'one'

With set-error-stack:

import setErrorStack from 'set-error-stack'

const error = new Error('one')
console.log(error.stack) // 'Error: one ...'
console.log(error.message) // 'one'

setErrorStack(error, error.stack.replace('one', 'two'))
console.log(error.stack) // 'Error: two ...'
console.log(error.message) // 'two'


npm install set-error-stack

This package works in both Node.js >=18.18.0 and browsers.

This is an ES module. It must be loaded using an import or import() statement, not require(). If TypeScript is used, it must be configured to output ES modules, not CommonJS.


setErrorStack(error, stack)

error Error | any
stack string
Return value: Error

Sets error.stack = stack. If needed, also modifies error.message accordingly.

Returns error. If error is not an Error instance, it is converted to one.
