【中文标题】如何迁移到 react-redux-firebase v3【英文标题】:How to migrate to v3 of react-redux-firebase 【发布时间】:2019-06-06 08:25:23 【问题描述】:我尝试使用新的 ReactReduxFirebaseProvider 和 createFirestoreInstance 将我的项目从 react-redux-firebase v2 迁移到 v3
我的代码现在可以正常工作。但是升级到 react-redux-firebase v3 之后,就不是了。我收到此错误:
这是我的 index.js:
import React from 'react';
import ReactDOM from 'react-dom';
import './index.css';
import App from './App';
import registerServiceWorker from './registerServiceWorker';
import createStore, applyMiddleware, compose from 'redux'
import rootReducer from './store/reducers/rootReducer'
import Provider from 'react-redux'
import thunk from 'redux-thunk'
import reduxFirestore, getFirestore from 'redux-firestore';
import reactReduxFirebase, getFirebase from 'react-redux-firebase';
import fbConfig from './config/fbConfig'
const store = createStore(rootReducer,
compose(
applyMiddleware(thunk.withExtraArgument(getFirebase,
getFirestore)),
reactReduxFirebase(fbConfig), // redux binding for firebase
reduxFirestore(fbConfig) // redux bindings for firestore
)
);
ReactDOM.render(<Provider store=store><App /></Provider>,
document.getElementById('root'));
registerServiceWorker();
我试图从他们自己的迁移指南中实现它:http://react-redux-firebase.com/docs/v3-migration-guide.html#what-changed 但我没有得到它......也许我还有很多东西要学。但是,如果有人能指出我正确的方向,那就太好了。
我尝试更改代码但没有任何好的结果:
import React from 'react';
import ReactDOM from 'react-dom';
import './index.css';
import App from './App';
import registerServiceWorker from './registerServiceWorker';
import createStore, applyMiddleware, compose from 'redux'
import rootReducer from './store/reducers/rootReducer'
import Provider from 'react-redux'
import thunk from 'redux-thunk'
import ReactReduxFirebaseProvider, getFirebase from 'react-redux-firebase';
import createFirestoreInstance, getFirestore from 'redux-firestore'
import fbConfig from './config/fbConfig'
const store = createStore(rootReducer,
compose(
applyMiddleware(thunk.withExtraArgument(getFirebase, getFirestore)),
)
);
const rrfProps =
firebase,
config: fbConfig,
dispatch: store.dispatch,
createFirestoreInstance
ReactDOM.render(
<Provider store=store>
<ReactReduxFirebaseProvider ...rrfProps>
<App />
</ReactReduxFirebaseProvider>
</Provider>, document.getElementById('root'));
registerServiceWorker();
【问题讨论】:
【参考方案1】:看起来你实际上没有将 react-redux-firebase 更新到 v3。
你能检查 package.json 中 react-redux-firebase 的版本吗?如果它仍然是 v2,那么您可以使用 npm install react-redux-firebase@next
将其更新到 v3
v3 是下一个主要版本,目前还不能使用npm install react-redux-firebase@latest
安装。
【讨论】:
【参考方案2】:您必须导入 firebase。请参阅下面的代码更新。
import React from 'react';
import ReactDOM from 'react-dom';
import './index.css';
import App from './App';
import registerServiceWorker from './registerServiceWorker';
import createStore, applyMiddleware, compose from 'redux'
import rootReducer from './store/reducers/rootReducer'
import Provider from 'react-redux'
import thunk from 'redux-thunk'
import ReactReduxFirebaseProvider, getFirebase from 'react-redux-firebase';
import createFirestoreInstance, getFirestore from 'redux-firestore'
//import fbConfig from './config/fbConfig'
import firebase from 'firebase/app';
import 'firebase/auth';
import 'firebase/analytics';
import 'firebase/firestore'
var fbConfig = ;
firebase.initializeApp(fbConfig);
firebase.analytics();
firebase.firestore();
const store = createStore(rootReducer,
compose(
applyMiddleware(thunk.withExtraArgument(getFirebase, getFirestore)),
)
);
const rrfProps =
firebase,
config: fbConfig,
dispatch: store.dispatch,
createFirestoreInstance
ReactDOM.render(
<Provider store=store>
<ReactReduxFirebaseProvider ...rrfProps>
<App />
</ReactReduxFirebaseProvider>
</Provider>, document.getElementById('root'));
registerServiceWorker();
【讨论】:
【参考方案3】:我是初级 React 开发人员,我在我的项目中使用 React、Redux 和 Firebase v3.8.2。我遇到了同样的问题,即使用您分享的这些将我的应用程序与 firebase 连接起来。
所以我已经找到解决方案了:
import React from 'react';
import ReactDOM from 'react-dom';
import './index.css';
import App from './App';
//redux
import createStore, applyMiddleware, compose from 'redux';
import Provider from 'react-redux';
import rootReducer from './store/reducers/rootReducer';
import thunk from 'redux-thunk';
//firebase
import ReactReduxFirebaseProvider, getFirebase from 'react-redux-firebase';
import createFirestoreInstance ,reduxFirestore, getFirestore from 'redux-firestore';
//config
import fbConfig from './config/fbConfig'; //to see
import firebase from 'firebase/app';
const store= createStore(rootReducer,
compose(
applyMiddleware(thunk.withExtraArgument(getFirebase, getFirestore)),
reduxFirestore(fbConfig)
)
);
const rrfProps =
firebase,
config: fbConfig,
dispatch: store.dispatch,
createFirestoreInstance
ReactDOM.render(<React.StrictMode>
<ReactReduxFirebaseProvider ...rrfProps>
<Provider store=store>
<App />
</Provider>
</ReactReduxFirebaseProvider>
</React.StrictMode>,
document.getElementById('root'));
祝大家好运??
