extended-error
ExtendedError makes it easier to create Error with custom properties
installation
npm install @tfso/extended-error
Usage
const ExtendedError = require('extended-error')
let error = new ExtendedError('Not found', {status:404})
console.log(error.message) // Not found
console.log(error.status) // 404
console.log(error instanceof Error) // true
console.log(error instanceof ExtendedError) // true
console.log(error.stack) // 'Error: Not found\n at repl:1:9\n ...
This:
throw new ExtendedError('Not found', {status:404})
is equivalent to:
let error = new Error('Not found')
error.status = 400
throw error
