我正在尝试减少使用redux键入的flow代码的样板。
特别是，我希望避免手动定义action types，但让flow使用typed action creators技巧从ExtractReturn中推断出它们（如type _ExtractReturn<B, F: (...args: any[]) => B> = B;
type ExtractReturn<F> = _ExtractReturn<*, F>;
中所述3}}或Shane Osbourne post）：
action.id但它没有发现简单错误，例如它应该发现number是string而不是reducer：Martin Hochel post。
如果操作是“手动”定义的，则会收到错误：Try Flow。
如何在Shane Osbourne post函数中正确捕获所有错误，而无需手动编写样板代码？
Flow Try提供的includeTeamDriveItems似乎有效。看着它。实际上，它也有同样的问题。试着在帖子上发表评论来发出信号。请参阅评论Try Flow 答案 0 :(得分：0)
如果您有兴趣，我设法让Flow抓住您的示例没有捕获的错误。 Here is the code
毫无疑问，黑客。我从this Github issue得到了这个想法。
除此之外，我无法提供更多见解。我自己在寻找更好的解决方案。
编辑：在挖掘了更多内容之后，我发现exception

实用程序类型可以提供一些帮助：
$Call在此之后，或许值得将type Action =
| $Call<typeof get, number>
| $Call<typeof del, number>
| $Call<typeof set, number, string>
模式抽象为自己的参数类型。但是，我对此时流量的了解是有限的，所以我的一些尝试并没有取得丰硕成果。
