const { default: ReqError, catchError } = require('req-error')

  // Do your stuff...
  throw new ReqError('This is just a demo', 400)
})

  // Do your stuff...
  throw new ReqError('This is just another demo', 401)
})

Some possible usages of ReqError:

new ReqError('Message', 404)

new ReqError(['Message', 404])
// { message: "Message", statusCode: 404 }

new ReqError(['Message', 404], 500)
// { message: "Message", statusCode: 500 }

// Even more simple:
throw 'Error message'
throw ['Error message', 404]
