v2.*.* to v3.*.* Migration Guide

What Changed

Features

• Support react-redux v6 and new React Context API - #581. This mean no more reactReduxFirebase and reduxFirestore store enhancers (instance is passed through the new React context API) - #581
• React hooks (requires react ^16.8.0) useFirebase, useFirestore, useFirestoreConnect, and useFirebaseConnect - (Tons of work by @illuminist)

Breaking Changes

• Removed from API:
  • reactReduxFirebase store enhancer (firebase instance is now created by context providers)
  • createFirebaseConnect and createFirestoreConnect (see below)
  • signIn option from createUser (new user is automatically signed in through Firebase SDK) - #513
• componentDidMount used in place of componentWillMount for data loading in firebaseConnect and firestoreConnect
• helpers is no longer exported in top level API - import helpers directly instead
• firebaseStateReducer is no longer exported in top level API - import reducer or firebaseReducer
• authIsReady should only be used for SSR - if you are waiting for auth to be ready, state should be used. For an example see the wait for auth to load recipe.

Change Snippets

Remove createFirebaseConnect and createFirestoreConnect

These are no longer needed since the extended firebase instance is now loaded through react context instead of through store.firebase.

- const firebaseConnect = createFirebaseConnect('otherStoreKey') - const firestoreConnect = createFirestoreConnect('otherStoreKey') 

Remove Store Enhancer

Replace store enhancer with ReactReduxFirebaseProvider

Code Examples

v2.*.*

• Pass Firebase Instance in place of
• firebaseReducer is now available to use in place of firebaseStateReducer (which is still available)

reducer.js

import { combineReducers } from 'redux' import { firebaseReducer } from 'react-redux-firebase' // import { firestoreReducer } from 'redux-firestore' // <- needed if using firestore // Add firebase to reducers export default combineReducers({ firebase: firebaseReducer, // firestore: firestoreReducer // <- needed if using firestore }) 

createReduxStore.js

import { createStore } from 'redux' import { reactReduxFirebase } from 'react-redux-firebase' // import { reduxFirestore } from 'redux-firestore' // <- needed if using firestore import reducer from './reducer' const initialState = {} const fbConfig = {} // object containing Firebase config const rrfConfig = { userProfile: 'users' } // react-redux-firebase config // Initialize firebase instance firebase.initializeApp(fbConfig) export default () => { return createStore( rootReducer, initialState, compose( reactReduxFirebase(firebase, rrfConfig), // pass in firebase instance instead of config // reduxFirestore(firebase) // <- needed if using firestore // applyMiddleware(...middleware) // to add other middleware ) ) } 

App.js

createReduxStore.js
