如何在 Django 應用程序中用 react ContextAPI 替換 Redux (How can you replace Redux by the react ContextAPI in a Django App)

我最近學會瞭如何使用 createContext() 來模仿 redux 的行為。我知道如何使用 react contextAPI 和 react hooks。但是現在，我嘗試連接 django 和 react，但是每個教程都提到了 Redux。如何用 createContext + react hooks 替換 Redux？

參考解法

方法 1:

You can combine createContext and useReducer like this:

const StoreContext = React.createContext();

const App = () => {
  const [state, dispatch] = useReducer(reducer, initialState);
  return (
    <StoreContext.Provider value={{ state, dispatch }}>
      <Content />
    </StoreContext.Provider>
  );
}

Inside your components you could then use useContext(StoreContext) to get access to your state and dispatch.
