Error subclasses are lost when deserializing

const {serializeError, deserializeError} = require('serialize-error');

class MyError extends Error {
    constructor(message) {
        super(message);
        this.name = 'MyError'
    }
}

const original = new MyError('This is my error');
const serialized = serializeError(original);
const deserialized = deserializeError(serialized);

original will be a MyError but deserialized will be a plain Error

I think deserializeError should support custom error types, if passed as an argument (so they are known and explicit):

const deserialized = deserializeError(serialized, {constructors: [MyError, BusinessError, ErrorError]});

Native errors also should be automatically supported, like TypeError

Sure. I don’t think it should contain the built-in error types though. We don’t want users to be able to remove those. So maybe it should be named customErrorClasses? I would go with Set. It’s the correct data structure for this.

You can open a new issue. Given it’s a complex error, it first needs proper serialization support.
