Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Installation

npm install --save react-redux-firebase

This assumes you are using npm as your package manager.

If you're not, you can access the library on unpkg, download it, or point your package manager to it. Theres more on this in the Builds section below.

Older Versions

Interested in support for versions of react-redux before v6 or the new react context API? Checkout the v2.*.* versions (installed through npm i --save react-redux-firebase^@2.5.0).

Use

Include firebaseReducer (reducer) while creating your redux store then pass dispatch and your firebase instance to ReactReduxFirebaseProvider (context provider):

import React from 'react'
import { render } from 'react-dom'
import { Provider } from 'react-redux'
import firebase from 'firebase/app'
import 'firebase/auth'
// import 'firebase/firestore' // <- needed if using firestore
// import 'firebase/functions' // <- needed if using httpsCallable
import { createStore, combineReducers, compose } from 'redux'
import { ReactReduxFirebaseProvider, firebaseReducer } from 'react-redux-firebase'
// import { createFirestoreInstance, firestoreReducer } from 'redux-firestore' // <- needed if using firestore

const fbConfig = {}

// react-redux-firebase config
const rrfConfig = {
  userProfile: 'users'
  // useFirestoreForProfile: true // Firestore for Profile instead of Realtime DB
}

// Initialize firebase instance
firebase.initializeApp(fbConfig)

// Initialize other services on firebase instance
// firebase.firestore() // <- needed if using firestore
// firebase.functions() // <- needed if using httpsCallable

// Add firebase to reducers
const rootReducer = combineReducers({
  firebase: firebaseReducer
  // firestore: firestoreReducer // <- needed if using firestore
})

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

const rrfProps = {
  firebase,
  config: rrfConfig,
  dispatch: store.dispatch,
  // createFirestoreInstance // <- needed if using firestore
}

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

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

The Firebase instance can then be grabbed from context within your components (withFirebase and firebaseConnect Higher Order Components provided to help):

Add Data

import React from 'react'
import { useFirebase } from 'react-redux-firebase'

export default function Todos() {
  const firebase = useFirebase()

  function addSampleTodo() {
    const sampleTodo = { text: 'Sample', done: false }
    return firebase.push('todos', sampleTodo)
  }

  return (
    <div>
      <h1>New Sample Todo</h1>
      <button onClick={addSampleTodo}>
        Add
      </button>
    </div>
  )
}

Load Data (listeners automatically managed on mount/unmount)

import React from 'react'
import PropTypes from 'prop-types'
import { useSelector } from 'react-redux'
import { useFirebaseConnect, isLoaded, isEmpty } from 'react-redux-firebase'

export default function Todos() {
  useFirebaseConnect([
    'todos' // { path: '/todos' } // object notation
  ])
  
  const todos = useSelector(state => state.firebase.ordered.todos)

  if (!isLoaded(todos)) {
    return <div>Loading...</div>
  }

  if (isEmpty(todos)) {
    return <div>Todos List Is Empty</div>
  }

  return (
    <div>
      <ul>
        {
          Object.keys(todos).map(
            (key, id) => (
              <TodoItem key={key} id={id} todo={todos[key]}/>
            )
          )
        }
      </ul>
    </div>
  )
}

Queries Based On Route Params

It is common to make a detail page that loads a single item instead of a whole list of items. A query for a specific Todos can be created using

import React from 'react'
import PropTypes from 'prop-types'
import { get } from 'lodash'
import { useSelector } from 'react-redux'
import { useFirebaseConnect } from 'react-redux-firebase'
import { useParams } from 'react-router-dom'

export default function Todo() {
  const { todoId } = useParams() // matches todos/:todoId in route

  useFirebaseConnect([
    { path: `todos/${todoId}` } // create todo listener
    // `todos/${props.params.todoId}` // equivalent string notation
  ])
  
  const todo = useSelector(({ firebase: { data } }) => data.todos && data.todos[todoId])

  function updateTodo() {
    return firebase.update(`todos/${params.todoId}`, { done: !todo.isDone })
  }

  return (
    <div>
      <input
        name="isDone"
        type="checkbox"
        checked={todo.isDone}
        onChange={updateTodo}
      />
      <span>{todo.label}</span>
    </div>
  )
}

Load Data On Click

import React from 'react'
import { useSelector } from 'react-redux'
import { useFirebase, isLoaded, isEmpty } from 'react-redux-firebase'

function TodosList() {
  const todos = useSelector(state => state.firebase.ordered.todos)

  if (!isLoaded(todos)) {
    return <div>Loading...</div>
  }

  if (isEmpty(todos)) {
    return <div>Todos List Is Empty</div>
  }

  return (
    <ul>
      {
        Object.keys(todos).map((key, id) =>
          <TodoItem key={key} id={id} todo={todos[key]}/>
        )
      }
    </ul>
  )
}

function Todos() {
  const firebase = useFirebase()

  return (
    <div>
      <h1>Todos</h1>
      <EnhancedTodosList />
      <button onClick={() => firebase.watchEvent('value', 'todos')}>
        Load Todos
      </button>
    </div>
  )
}

// Export enhanced component
export default Todos

Firestore

If you plan to use Firestore, you should checkout redux-firestore. It integrates nicely with react-redux-firebase and it allows you to run Real Time Database and Firestore along side each other.

react-redux-firebase provides the firestoreConnect HOC (similar to firebaseConnect) for easy setting/unsetting of listeners.

Currently react-redux-firebase still handles auth when using redux-firestore - The future plan is to also have auth standalone auth library that will allow the developer to choose which pieces they do/do not want.

State Based Query Snippet

Snippet showing querying based on data in redux state. One of the more common examples 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

Builds

Most commonly people consume Redux Firestore as a CommonJS module. This module is what you get when you import redux in a Webpack, Browserify, or a Node environment.

If you don't use a module bundler, it's also fine. The redux-firestore npm package includes precompiled production and development UMD builds in the dist folder. They can be used directly without a bundler and are thus compatible with many popular JavaScript module loaders and environments. For example, you can drop a UMD build as a <script> tag on the page. The UMD builds make Redux Firestore available as a window.ReactReduxFirebase global variable.

It can be imported like so:

<script src="../node_modules/react-redux-firebase/dist/react-redux-firebase.min.js"></script>
<script src="../node_modules/redux-firestore/dist/redux-firestore.min.js"></script>
<!-- or through cdn: <script src="https://unpkg.com/[email protected]/dist/react-redux-firebase.min.js"></script> -->
<!-- or through cdn: <script src="https://unpkg.com/[email protected]/dist/redux-firestore.min.js"></script> -->
<script>console.log('react redux firebase:', window.ReactReduxFirebase)</script>

Note: In an effort to keep things simple, the wording from this explanation was modeled after the installation section of the Redux Docs.
