Features

Example

import errorCustomClass from 'error-custom-class'

const UserError = errorCustomClass('UserError')
const DatabaseError = errorCustomClass('DatabaseError')

try {
  throw new UserError('message')
} catch (error) {
  console.log(error.name) // 'UserError'
  console.log(error instanceof UserError) // true
}

Install

npm install error-custom-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.

API

The API is designed for simplicity. For more customization, error-class-utils should be used instead.

errorCustomClass(errorName)

errorName string
Return value: CustomError

Creates a custom error class.
