Class: ExtensibleError

ExtensibleError


<abstract> new ExtensibleError(message [, dropInternalStackFrames])

Base class of custom error classes, extending the native Error class.

This class has been introduced to fix the Babel-related issues with extending the native JavaScript (Error) classes.

Parameters:
Name Type Argument Default Description
message string

The message describing the cause of the error.

dropInternalStackFrames boolean <optional>
true

Whether or not the call stack frames referring to the constructors of the custom errors should be excluded from the stack of this error (just like the native platform call stack frames are dropped by the JS engine). This flag is enabled by default.

_dropInternalStackFrames :boolean

Type:
  • boolean

_nativeError :Error

Native error instance we use to generate the call stack. For some reason some browsers do not generate call stacks for instances of classes extending the native Error class, so we bypass this shortcoming this way.

Type:

<nullable> _stack :string

The internal cache of the generated stack. The cache is filled upon first access to the stack property.

Type:
  • string

message :string

The message describing the cause of the error.

Type:
  • string

name :string

The name of this error, used in the generated stack trace.

Methods


getHttpStatus()

Returns the HTTP status to send to the client.

If the error has occurred at the client-side, the status code is used to determine the error page to show to the user.

This method is a shorthand for the following code snippet: this.getParams().status || 500.
