bie*_*ier 3 redux redux-saga react-redux
尝试使用redux saga运行reduxdevtools:
收到此错误:
Error
Before running a Saga, you must mount the Saga middleware on the Store using applyMiddleware

这是我的jscode:
const store = createStore(
reducer,
applyMiddleware(sagaMiddleware),
window.__REDUX_DEVTOOLS_EXTENSION__ && window.__REDUX_DEVTOOLS_EXTENSION__()
);

如何使用saga运行此devtool?或者,否则会起作用吗? 码笔
上一个答案(由 trkaplan 提供)使用来自“redux-devtools-extension”包的导入方法 composeWithDevTools。如果你不想安装这个包,你可以使用这个代码(基于文档):
const composeEnhancers = typeof window === 'object' && window['__REDUX_DEVTOOLS_EXTENSION_COMPOSE__'] ?
window['__REDUX_DEVTOOLS_EXTENSION_COMPOSE__']({ }) : compose;
const enhancer = composeEnhancers(
applyMiddleware(thunkMiddleware, sagaMiddleware, /*other middleware*/),
/* other store enhancers if any */
);
const emptyReducer = () => {};
const store = createStore(emptyReducer, enhancer);

我用终极版-devtools扩展包这里所描述的,终极版-devtools扩展文档。
添加软件包后,我将商店定义替换为:
const store = createStore(
reducer,
composeWithDevTools(
applyMiddleware(sagaMiddleware)
)
);
