高级序列化

¥Advanced serialization

子进程支持基于 node:v8 模块的序列化 API 的 IPC 序列化机制，基于 HTML 结构化克隆算法。这通常更强大，支持更多的内置 JavaScript 对象类型，如 BigInt、Map 和 Set、ArrayBuffer 和 TypedArray、Buffer、Error、RegExp 等。

¥Child processes support a serialization mechanism for IPC that is based on the serialization API of the node:v8 module, based on the HTML structured clone algorithm. This is generally more powerful and supports more built-in JavaScript object types, such as BigInt, Map and Set, ArrayBuffer and TypedArray, Buffer, Error, RegExp etc.

但是，这种格式不是 JSON 的完整超集，例如 在此类内置类型的对象上设置的属性将不会通过序列化步骤传递。此外，性能可能不等同于 JSON，具体取决于传递数据的结构。因此，此功能需要在调用 child_process.spawn() 或 child_process.fork() 时通过将 serialization 选项设置为 'advanced' 来选择启用。

¥However, this format is not a full superset of JSON, and e.g. properties set on objects of such built-in types will not be passed on through the serialization step. Additionally, performance may not be equivalent to that of JSON, depending on the structure of the passed data. Therefore, this feature requires opting in by setting the serialization option to 'advanced' when calling child_process.spawn() or child_process.fork().
