As of version 8.0.0 node has exposed a serialization api which is compatible with structured clone. https://nodejs.org/api/v8.html#v8_serialization_api

    const v8 = require('v8');
    const buf = v8.serialize({a: 'foo', b: new Date()});
    const cloned = v8.deserialize(buf);
    cloned.b.getMonth();
