Properly update an error's class.
Please reach out if you're looking for a Node.js API or CLI engineer (11 years of experience). Most recently I have been Netlify Build's and Netlify Plugins' technical lead for 2.5 years. I am available for full-time remote positions.
stack
with its new name
import setErrorClass from 'set-error-class'
const typeError = new TypeError('test')
console.log(typeError instanceof TypeError) // true
console.log(typeError.name) // 'TypeError'
console.log(typeError.constructor) // TypeError
console.log(typeError.stack) // TypeError: test ...
const rangeError = setErrorClass(typeError, RangeError)
console.log(rangeError === typeError) // true
console.log(rangeError instanceof RangeError) // true
console.log(rangeError.name) // 'RangeError'
console.log(rangeError.constructor) // RangeError
console.log(rangeError.stack) // RangeError: test ...
npm install set-error-class
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.
error
Error | unknown
ErrorClass
typeof Error
Return value: Error
Sets the error
's
prototype,
name
and
constructor
.
error
is returned. If error
is not an Error
instance, it is converted to
one.
error.stack
In V8 (Chrome, Node.js, Deno, etc.),
error.stack
includes
error.name
.
It is updated accordingly.
ErrorClass
is assigned to error
, but its constructor is not called. In some
instances, this might lead to invalid errors. If ErrorClass
's constructor is
doing anything significant, that logic should be performed on error
as well.
