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 is a subclass of Error.
AggregateError()
Creates a new AggregateError object.
Also inherits instance properties from its parent Error.
These properties are defined on AggregateError.prototype and shared by all AggregateError instances.
AggregateError.prototype.constructor
The constructor function that created the instance object. For AggregateError instances, the initial value is the AggregateError constructor.
AggregateError.prototype.name
Represents the name for the type of error. For AggregateError.prototype.name, the initial value is "AggregateError".
These properties are own properties of each AggregateError instance.
errors
An array representing the errors that were aggregated.
Inherits instance methods from its parent Error.
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" ]
}
