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 - Next upcoming release. Currently, points to active progress with v1.5.0-* pre-releases
  • @canary - 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.

Other versions docs are available using the dropdown on the above docs link. For quick access:

Be aware of changes when using a version that is 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 { createStore, combineReducers, compose } from 'redux'
import { reactReduxFirebase, firebaseStateReducer } from 'react-redux-firebase'

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

const reduxFirebaseConfig = { userProfile: 'users' }

// Add redux Firebase to compose
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)

In components:

import React, { Component } 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,
  dataToJS,
  pathToJS
} from 'react-redux-firebase'

class Todos extends Component {
  static propTypes = {
    todos: PropTypes.object,
    auth: PropTypes.object,
    firebase: PropTypes.object
  }

  addTodo = () => {
    const { newTodo } = this.refs
    return this.props.firebase
      .push('/todos', { text: newTodo.value, done: false })
      .then(() => {
        newTodo.value = ''
        console.log('Todo Created!')
      })
      .catch((err) => {
        console.log('Error creating todo:', err) // error is also set to state.firebase.authError
      })
  }

  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 (
      <div>
        <h1>Todos</h1>
        <ul>
          {todosList}
        </ul>
        <input type="text" ref="newTodo" />
        <button onClick={this.handleAdd}>
          Add
        </button>
      </div>
    )
  }
}

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

Alternatively, if you choose to use decorators:

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

}

Decorators

Though they are optional, it is highly recommended that you use 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:

Without Decorators

class SomeComponent extends Component {

}
export default connect()(SomeComponent)

vs.

With Decorators

@connect()
export default class SomeComponent extends Component {

}

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"]
}

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.

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?

  4. How does connect relate to firebaseConnect?

    data flow
