Class: ToorError

A base class for errors.

Extends

• Error

Extended by

• NotFoundToorError
• BadRequestToorError

Constructors

Constructor

new ToorError(errorCode: string, message: string, httpStatusCode: number): ToorError

Creates a new ToorError.

Parameters

Parameter	Type	Description
errorCode	string	Typically the class name of the error.
message	string	The error message.
httpStatusCode	number	The HTTP status code.

Returns

ToorError

Overrides

Error.constructor

cause?

optional cause?: unknown

Error.message

stack?

optional stack?: string

stackTraceLimit

static stackTraceLimit: number

The Error.stackTraceLimit property specifies the number of stack frames collected by a stack trace (whether generated by new Error().stack or Error.captureStackTrace(obj)).

The default value is 10 but may be set to any valid JavaScript number. Changes will affect any stack trace captured after the value has been changed.

If set to a non-number value, or set to a negative number, stack traces will not capture any frames.

string

Returns

number

captureStackTrace()

static captureStackTrace(targetObject: object, constructorOpt?: Function): void

Creates a .stack property on targetObject, which when accessed returns a string representing the location in the code at which Error.captureStackTrace() was called.

const myObject = {};
Error.captureStackTrace(myObject);
myObject.stack;  // Similar to `new Error().stack`

The first line of the trace will be prefixed with ${myObject.name}: ${myObject.message}.

The optional constructorOpt argument accepts a function. If given, all frames above constructorOpt, including constructorOpt, will be omitted from the generated stack trace.

The constructorOpt argument is useful for hiding implementation details of error generation from the user. For instance:

function a() {
  b();
}

function b() {
  c();
}

function c() {
  // Create an error without stack trace to avoid calculating the stack trace twice.
  const { stackTraceLimit } = Error;
  Error.stackTraceLimit = 0;
  const error = new Error();
  Error.stackTraceLimit = stackTraceLimit;

  // Capture the stack trace above function b
  Error.captureStackTrace(error, b); // Neither function c, nor b is included in the stack trace
  throw error;
}

a();

Parameters

Parameter	Type
targetObject	object
constructorOpt?	Function

Returns

void
