redux - uncaught TypeError: Cannot read property 'apply' of undefined(…)

Last updated on Feb 17, 2024 1 min read

剛剛在寫 reactjs publish 上去 Firebase 之後出現了以一的 error message
``
之後便顯示唔到這個 react page 了

做了一會 research 之後發現應該是 redux compose 既問題

解決方法: 我改了之前的

const store = createStore(
  reducers,
  initialState,
  compose(
    applyMiddleware(...middleware),
    window.__REDUX_DEVTOOLS_EXTENSION__ && window.__REDUX_DEVTOOLS_EXTENSION__()
  )
);

改成這樣便可以了

const store = createStore(
  reducers,
  initialState,
  compose(
    applyMiddleware(...middleware),
    window.REDUX_DEVTOOLS_EXTENSION
      ? window.REDUX_DEVTOOLS_EXTENSION()
      : (f) => f
  )
);

Hope you find it useful
