Error Handling

This sections focuses on client and server-side error handling during development and in production.


Represents custom error class that poses a structure for http errors. This should be preferred way of throwing custom errors as it adds an ability to define http status code with additional custom params. To create such error you need to import GenericError from @ima/core and instantiate it:

import { GenericError } from '@ima/core';

throw new GenericError(
'Something went wrong.',
{ status: 500, custom: 'param' } // error parameters

GenericError instance has 2 methods:

  • getParams() - Returns params argument (2nd argument) provided to the constructor.
  • getHttpStatus() - Returns status property from the params.
