如何将猫鼬模式解析为javascript对象？

Question

我有一个场景，我必须解析猫鼬对象并将其转换为标准javascript对象，但是我无法做到这一点，因为猫鼬在对象内部具有方法。有人可以帮我吗？

猫鼬对象

{
    key: {
      type: String,
      unique: true,
      min: 2,
      max: 50,
      validate: {
        validator: function(value: string) {
          return /^[A-Za-z0-9 ]{3,20}$/.test(value);
        },
        message: 'key is invalid.',
      },
      required: [true, 'key is required'],
    },
    key1: {
      type: String,
      validate: {
        validator: function(value: string) {
          return /^[A-Za-z0-9 ]{3,20}$/.test(value);
        },
        message: 'key1 is invalid',
      },
      required: [true, 'key1 is required'],
    },
  };

预期产量

{
key:{
  unique: true, 
  type: 'string', 
  min:2, 
  max:50, 
  validation: /^[A-Za-z0-9 ]{3,20}$/
  }, 
key1: {
  type: 'string', 
  validation: /^[A-Za-z0-9 ]{3,20}$/
  }
}
