我喜欢 JSON-LD、Hydra 的优势，并且刚刚了解了 NgRx/data。

我尝试在没有自定义的情况下使用它，这显然不起作用。今天我花了几个小时在文档上，这给我留下了更多问题。

重要的是，我不想牺牲任何关于收藏的信息。所以我不能只使用自定义效果。

关于如何解决这个问题的任何想法？

我看到了一种方法：

  1. 在模型中添加“@”属性：
export interface HydraEntity {
    '@id': string;
    '@type': string;
}

export interface Author extends HydraEntity{
    id: number;
    name: string;
}
  1. 更改 Ngrx/data 处理 API 响应的方式，添加额外的“hydra:*”字段： https ://ngrx.io/guide/data/entity-metadata#additionalcollectionstate

您应该能够减少您所在州的结果。

我从未尝试过，但我认为它遵循了这个问题：https ://github.com/ngrx/platform/issues/1948
