Introducing the Socket Python SDK
The initial version of the Socket Python SDK is now on PyPI, enabling developers to more easily interact with the Socket REST API in Python projects.
set-error-message
Advanced tools
Properly update an error's message.
In V8 (Chrome, Node.js, Deno, etc.),
error.stack
includes
error.message
.
However, if error.message
is modified, error.stack
might not be updated and
still contain the previous message.
This library fixes it by setting error.message
while updating error.stack
accordingly. This works on any JavaScript engine.
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.
Without set-error-message
:
const error = new Error('one')
console.log(error.message) // 'one'
console.log(error.stack) // 'Error: one ...'
error.message = 'two'
console.log(error.message) // 'two'
console.log(error.stack) // 'Error: one ...'
With set-error-message
:
import setErrorMessage from 'set-error-message'
const error = new Error('one')
console.log(error.message) // 'one'
console.log(error.stack) // 'Error: one ...'
setErrorMessage(error, 'two')
console.log(error.message) // 'two'
console.log(error.stack) // 'Error: two ...'
npm install set-error-message
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.

newMessage

Return value: Error
Sets error.message = newMessage
