Getting Started

Before Use

Peer Dependencies

Install peer dependencies: npm i --save redux react-redux


Though they are optional, it is highly recommended that you used decorators with this library. The Simple Example shows implementation without decorators, while the Decorators Example shows the same application with decorators implemented.

A side by side comparison using react-redux's connect function/HOC is the best way to illustrate the difference:

class SomeComponent extends Component {

export default connect()(SomeComponent)


export default class SomeComponent extends Component {


In order to enable this functionality, you will most likely need to install a plugin (depending on your build setup). For Webpack and Babel, you will need to make sure you have installed and enabled babel-plugin-transform-decorators-legacy by doing the following:

  1. run npm i --save-dev babel-plugin-transform-decorators-legacy
  2. Add the following line to your .babelrc:
     "plugins": ["transform-decorators-legacy"]


npm install --save react-redux-firebase

Add Reducer

Include firebase in your combine reducers function:

import { combineReducers } from 'redux'
import { firebaseStateReducer } from 'react-redux-firebase'

// Add firebase to reducers
const rootReducer = combineReducers({
  firebase: firebaseStateReducer

Compose Function

import { compose } from 'redux'
import { reactReduxFirebase } from 'react-redux-firebase'

// Firebase config
const firebaseConfig = {
  apiKey: '<your-api-key>',
  authDomain: '<your-auth-domain>',
  databaseURL: '<your-database-url>',
  storageBucket: '<your-storage-bucket>'
// react-redux-firebase options
const config = {
  userProfile: 'users', // firebase root where user profiles are stored
  enableLogging: false, // enable/disable Firebase's database logging

// Add redux Firebase to compose
const createStoreWithFirebase = compose(
  reactReduxFirebase(firebaseConfig, config)

// Create store with reducers and initial state
const store = createStoreWithFirebase(rootReducer, initialState)

View the config section for full list of configuration options.

Use in Components

import React, { Component } from 'react'
import PropTypes from 'prop-types'
import { connect } from 'react-redux'
import { firebaseConnect, isLoaded, isEmpty, dataToJS } from 'react-redux-firebase'

  'todos' // corresponds to 'todos' root on firebase
  ({ firebase }) => ({
    // todos prop set to firebase data in redux under '/todos'
    todos: dataToJS(firebase, 'todos'),
export default class Todos extends Component {
  static propTypes = {
    todos: PropTypes.object,
    firebase: PropTypes.object

  handleAdd = () => {
    const {newTodo} = this.refs
    const { firebase } = this.props
    // Add a new todo to firebase
    firebase.push('/todos', { text: newTodo.value, done: false })
    newTodo.value = ''

  render() {
    const { todos } = this.props;

    // Build Todos list if todos exist and are loaded
    const todosList = !isLoaded(todos)
      ? 'Loading'
      : isEmpty(todos)
        ? 'Todo list is empty'
        : Object.keys(todos).map(
            (key, id) => (
              <TodoItem key={key} id={id} todo={todos[key]}/>

    return (
        <input type="text" ref="newTodo" />
        <button onClick={this.handleAdd}>

Alternatively, if you choose not to use decorators, your connect function will look like so:

const wrappedTodos = firebaseConnect([

export default connect(
  ({firebase}) => ({
    todos: dataToJS(firebase, 'todos'),
