Introduction

The @poppinss/exception package provides with a base Exception class that can be used to create custom errors with support for defining the error status, error code, and help description.

``ts import { Exception } from '@poppinss/exception'

class ResourceNotFound extends Exception { static code = 'E_RESOURCE_NOT_FOUND' static status = 404 static message = 'Unable to find resource' }

throw new ResourceNotFound()`

`$3`

You can also create an anonymous exception class using the createError method. The return value is a class constructor that accepts an array of values to use for message interpolation.

The interpolation of error message is performed using the util.format method.

`ts import { createError } from '@poppinss/exception'

const E_RESOURCE_NOT_FOUND = createError<[number]>( 'Unable to find resource with id %d', 'E_RESOURCE_NOT_FOUND' )

const id = 1 throw new E_RESOURCE_NOT_FOUND([id])``
