Redux bindings for Firebase. Includes Higher Order Component for use with React.

react-redux-firebase

Redux bindings for Firebase. Includes Higher Order Component (HOC) for use with React.

Demo

The Material Example is deployed to demo.react-redux-firebase.com.

Features

• Integrated into redux
• Out of the box support for authentication (with auto load user profile)
• Full Firebase Platform Support Including Real Time Database, Firestore, and Storage
• Automatic binding/unbinding of listeners using firebaseConnect Higher Order Component
• Population capability (similar to mongoose's populate or SQL's JOIN)
• Support small data ( using value ) or large datasets ( using child_added, child_removed, child_changed )
• queries support ( orderByChild, orderByKey, orderByValue, orderByPriority, limitToLast, limitToFirst, startAt, endAt, equalTo right now )
• Tons of examples of integrations including redux-thunk and redux-observable
• Server Side Rendering Support
• react-native support using native modules or web sdk

Install

npm install --save react-redux-firebase

Other Versions

The above install command will install the @latest tag. You may also use the following tags when installing to get different versions:

• @next - Most possible up to date code. Currently, points to active progress with v2.0.0-* pre-releases. Warning: Syntax is different than current stable version.

Be aware of changes when using a version that is not tagged @latest. Please report any issues you encounter, and try to keep an eye on the releases page for updates.

Use

Note: If you are just starting a new project, you may want to use v2.0.0 since it has an even easier syntax. For clarity on the transition, view the v1 -> v2 migration guide

Include reactReduxFirebase in your store compose function and firebaseStateReducer in your reducers:

import React from 'react'
import { render } from 'react-dom'
import { Provider } from 'react-redux'
import { createStore, combineReducers, compose } from 'redux'
import { reactReduxFirebase, firebaseStateReducer } from 'react-redux-firebase'
import Todos from './Todos' // find code below

const firebaseConfig = {
  apiKey: '<your-api-key>',
  authDomain: '<your-auth-domain>',
  databaseURL: '<your-database-url>',
  storageBucket: '<your-storage-bucket>'
}

const reduxFirebaseConfig = { userProfile: 'users' }

// Add reactReduxFirebase store enhancer
const createStoreWithFirebase = compose(
  reactReduxFirebase(firebaseConfig, reduxFirebaseConfig),
)(createStore)

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

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

// Setup react-redux so that connect HOC can be used
const App = () => (
  <Provider store={store}>
    <Todos />
  </Provider>
);

render(<App/>, document.getElementById('root'));

Todos component (./Todos):

import React from 'react'
import PropTypes from 'prop-types' // can also come from react if react <= 15.4.0
import { connect } from 'react-redux'
import { compose } from 'redux'
import { firebaseConnect, isLoaded, isEmpty, toJS } from 'react-redux-firebase'

const Todos = ({ todos }) => (
  <div>
    <h1>Todos</h1>
    <ul>
      {
        !isLoaded(todos)
          ? 'Loading'
          : isEmpty(todos)
            ? 'Todo list is empty'
            : toJS(todos).map(
                (key, id) => (
                  <TodoItem key={key} id={id} todo={todos[key]}/>
                )
              )
      }
    </ul>
  </div>
)

Todos.propTypes = {
  todos: PropTypes.object,
  firebase: PropTypes.object // comes from firebaseConnect
}

export default compose(
  firebaseConnect([
    'todos' // { path: 'todos' } // object notation
  ]),
  connect((state) => ({
    todos: state.firebase.getIn(['todos']), // in v2 todos: state.firebase.data.todos
  }))
)(Todos)

Alternatively, if you choose to use decorators:

@firebaseConnect([
  'todos' // { path: 'todos' } // object notation
])
@connect(
  ({ firebase }) => ({
    todos: state.firebase.getIn(['todos']) // in v2 todos: firebase.data.todos
  })
)
export default class Todos extends Component {
}

Examples

Examples folder is broken into two categories complete and snippets. /complete contains full applications that can be run as is, while /snippets contains small amounts of code to show functionality (dev tools and deps not included).

State Based Query Snippet

Snippet showing querying based on data in redux state. One of the most common examples of this is querying based on the current users auth UID.

Decorators Snippet

Snippet showing how to use decorators to simplify connect functions (redux's connect and react-redux-firebase's firebaseConnect)

Simple App Example

A simple example that was created using create-react-app's. Shows a list of todo items and allows you to add to them.

Material App Example

An example that user Material UI built on top of the output of create-react-app's eject command. Shows a list of todo items and allows you to add to them. This is what is deployed to redux-firebasev3.firebaseapp.com.

Generator

generator-react-firebase is a yeoman generator uses react-redux-firebase when opting to include redux.

FAQ

1. How is this different than redux-react-firebase?

   This library was actually originally forked from redux-react-firebase, but adds extended functionality such as:

   • populate functionality (similar to mongoose's populate or SQL's JOIN)
   • react-native support (web/js or native modules through react-native-firebase)
   • tons of integrations
   • profileFactory - change format of profile stored on Firebase
   • getFirebase - access to firebase instance that fires actions when methods are called
   • access to firebase's storage and messaging services
   • uniqueSet method helper for only setting if location doesn't already exist
   • Object or String notation for paths ([{ path: '/todos' }] equivalent to ['/todos'])
   • Action Types and other Constants are exposed for external usage (such as with redux-observable)
   • Server Side Rendering Support
   • Complete Firebase Auth Integration including signInWithRedirect compatibility for OAuth Providers

   Well why not combine?

   I have been talking to the author of redux-react-firebase about combining, but we are not sure that the users of both want that at this point. Join us on the redux-firebase gitter if you haven't already since a ton of this type of discussion goes on there.

   What about redux-firebase?

   The author of redux-firebase has agreed to share the npm namespace! Currently the plan is to take the framework agnostic redux core logic of react-redux-firebase and place it into redux-firebase). Eventually react-redux-firebase and potentially other framework libraries can depend on that core (the new redux-firebase).

2. Why use redux if I have Firebase to store state?

   This isn't a super quick answer, so I wrote up a medium article to explain

3. Where can I find some examples?

   • Recipes Section of the docs
   • examples folder contains complete example apps as well as useful snippets

4. How does connect relate to firebaseConnect?
