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.
