javascript - 我可以在 Javascript 中再次导入吗？

Question

例如在App.js中我有

let store = createStore(CombinedReducers, applyMiddleware(promiseMiddleware));

export { store }

当我在另一个文件中 import { store as mainStore } from './App' 时，我认为它将在成为 mainStore 之前运行 createStore 。我可以重新导入以便稍后再次运行此代码吗？对于本例，我确实想在测试之间重置 store 变量的状态。 createStore 方法就可以做到这一点。

Answer 1

For this instance I do want to reset the store variable's state in between tests. And the createStore method can do just that.

解决方案1:

如果你想重置存储变量，那么在 redux 中你可以 dispatch action 并将特定的存储值设置为您想要的任何值

解决方案 2: 怀疑未满

创建不同的商店变量，例如

导出 const store1 = createStore(CombinedReducers, applyMiddleware(promiseMiddleware));

导出 const store2 = createStore(CombinedReducers, applyMiddleware(promiseMiddleware));
