set-error-stack

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.

Example

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'

Install

npm install set-error-stack

This package works in both Node.js >=14.18.0 and browsers. It is an ES module and must be loaded using an import or import() statement, not require().

API

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.
