AggregateError

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.

AggregateError()

Creates a new AggregateError object.

AggregateError.prototype.message

Error message, defaults to "".

AggregateError.prototype.name

Error name, defaults to AggregateError.

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" ]
}
