True Myth / task / AggregateRejection

Class: AggregateRejection<E> ​

An error type produced when any produces any rejections. All rejections are aggregated into this type.

NOTE

This error type is not allowed to be subclassed.

Extends ​

  • Error

Type Parameters ​

E ​

E extends unknown[]

The type of the rejection reasons.

Constructors ​

Constructor ​

new AggregateRejection<E>(errors): AggregateRejection<E>

Parameters ​

errors ​

E

Returns ​

AggregateRejection<E>

Overrides ​

Error.constructor

Properties ​

cause? ​

optional cause: unknown

Inherited from ​

Error.cause

errors ​

readonly errors: E

message ​

message: string

Inherited from ​

Error.message

name ​

readonly name: "AggregateRejection" = 'AggregateRejection'

Overrides ​

Error.name

stack? ​

optional stack: string

Inherited from ​

Error.stack

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.

Error.stackTraceLimit

Methods ​

toString() ​

toString(): string

Returns a string representation of an object.

Returns ​

string

captureStackTrace() ​

static captureStackTrace(targetObject, constructorOpt?): 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.

js
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:

js
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();
