AggregateError
ponyfill.

> The AggregateError object represents an error when several errors need to be
> wrapped in a single error. It is thrown when multiple errors need to be
> reported by an operation, for example by Promise.any(), when all promises
> passed to it reject.

Install

``sh npm install aggregate-error-ponyfill --save`

`Usage`

`js import AggregateError from 'aggregate-error-ponyfill';

(async () => { try { await Promise.any([Promise.reject(new Error('some error'))]); } catch (e) { console.log(e instanceof AggregateError); // true console.log(e.message); // "All Promises rejected" console.log(e.name); // "AggregateError" console.log(e.errors); // [ Error: "some error" ] } })();

try { throw new AggregateError([new Error('some error')], 'Hello'); } catch (e) { console.log(e instanceof AggregateError); // true console.log(e.message); // "Hello" console.log(e.name); // "AggregateError" console.log(e.errors); // [ Error: "some error" ] }`

You can **use named export preferNativeif you wish to use native implementation if it’s available**. In all other cases, ponyfill will be used. Beware of caveats!

`API`

`$3`

Returns: AggregateError

Method description.

#### errors

Type: Iterable

An iterable of errors, may not actually be Error instances.

#### message

Type: string

An optional human-readable description of the aggregate error.

`Browser support`

Tested in IE11+ and all modern browsers.

It works in older IE versions such as IE9, but you can’t test forinstanceof AggregateErrordue to proper subclassing of native classes.

`Test`

Test suite is taken and modified fromes-shims/AggregateErrorpolyfill.

For automated tests, run npm run test:automated (append :watch` for watcher
support).
