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:

``js
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:

`js
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

`bash
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.

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.
