您可以在 xstate 中将嵌套状态与字符串路径匹配吗？

Question

来自 @xstate/react GitHub 存储库：

... for hierarchical and parallel machines, the state values will be objects, not strings. In this case, it's better to use state.matches(...)

看起来像这样：

if (current.matches({ loading: 'user' })) {
  return /* ... */;
}

但是你可以用 "loading.user" 替换 { loading: 'user' } 吗？

当然！至少对于当前版本的 xstate (4.6.7) 和 @xstate/react (0.8.1)，下面的 if 语句是等价的：

if (current.matches({ loading: 'user' })) {
  return /* ... */;
}

if (current.matches("loading.user")) {
  return /* ... */;
}

Can you match a nested state with string paths in xstate?
