Here is my code:
store.js
import {createStore, applyMiddleware, compose} from 'redux';
import {fromJS} from 'immutable';
import {routerMiddleware} from 'react-router-redux';
import createSagaMiddleware from 'redux-saga';
import createReducer from './reducers';
const sagaMiddleware = createSagaMiddleware();
export default function configureStore(initialState = {}, history) {
// Create the store with two middlewares
// 1. sagaMiddleware: Makes redux-sagas work
// 2. routerMiddleware: Syncs the location/URL path to the state
const middlewares = [sagaMiddleware, routerMiddleware(history)];
const enhancers = [applyMiddleware(...middlewares)];
const store = createStore(createReducer, fromJS(initialState), enhancers);
// Extensions
store.runSaga = sagaMiddleware.run;
store.asyncReducers = {}; // Async reducer registry
return store;
}
Routes.js
import React from 'react';
import {Route, Router, IndexRoute, browserHistory} from 'react-router';
import {syncHistoryWithStore} from 'react-router-redux';
import store from './store';
import Welcome from './containers/Welcome';
const history = syncHistoryWithStore(browserHistory, store);
const routes = (
<Router history={history}>
<Route path="/">
<IndexRoute component={Welcome} />
</Route>
</Router>
);
export default routes;
Index.js
import React from 'react';
import ReactDOM from 'react-dom';
import {browserHistory} from 'react-router';
import { Providers } from 'react-redux';
import configureStore from './store';
import routes from './routes';
const initialState = {};
const store = configureStore(initialState, browserHistory);
ReactDOM.render(
<Provider store={store}>
{routes}
</Provider>, document.getElementById('main-content')
);
I can't find where the culprit is. I tried to debug it, but can't found what really make it those error. error: Uncaught TypeError: store.getState is not a function
Any solution?
getState()Returns the current state tree of your application. It is equal to the last value returned by the store's reducer.
The way Redux works is simple. There is a central store that holds the entire state of the application. Each component can access the stored state without having to send down props from one component to another. There are three core components in Redux — actions, store, and reducers.
A store is an immutable object tree in Redux. A store is a state container which holds the application's state. Redux can have only a single store in your application. Whenever a store is created in Redux, you need to specify the reducer.
dispatch is a function of the Redux store. You call store. dispatch to dispatch an action. This is the only way to trigger a state change. With React Redux, your components never access the store directly - connect does it for you.
This is a typo that generated the error: TypeError: store.getState is not a function
Wrong
const store = createStore(()=>[], {}, applyMiddleware);
Correct
const store = createStore(()=>[], {}, applyMiddleware());
Notice the added parenthesis ()
on applyMiddleware
.
Notice that in your Routes.js
the store
is not being initialized properly. You should add these lines:
const initialState = {};
const store = configureStore(initialState, browserHistory);
as in your index.js
file.
