React.js Firebase Tutorial: Building Firestore CRUD Web Application
The comprehensive step by step tutorial on building Firestore Database CRUD Web Application using React.js and Google Firebase. Previously, we have created a tutorial of Firebase Firestore Database using React Native. Now, we have created the same tutorial for React.js but this time we implement to the Web Application. You will learn how to use Firebase Firestore Database with React.js Web Application. We cover the common CRUD (Create, Read, Update, Delete) operation of Firebase Firestore Database.
Shortcut to the steps:
- Setup Firebase Firestore Database
- Install and Create React App
- Install and Configure the Firebase Module
- Add React Router DOM
- Create List of Boards
- Create Show Details and Delete Board
- Create Add Board
- Create Edit Board
- Run and Test React.js and Firebase Web Application
The flow for this React Firebase application is very simple. Just, show the list of data, add, edit, delete and show the data details. They all done easily using the Firebase module. The Firebase configuration will be the same way as another tutorial about Firebase on our website.
Using React Firebase with standard Firebase library similar with another Front-end frameworks* Node.js (Recommended version)
We assume that you have already installed Node.js. Make sure Node.js command line is working (on Windows) or runnable in Linux/OS X terminal.
Setup Firebase Firestore Database
Setup Google Firebase is very simple. Open your browser then go to Google Firebase Consoleand log in using your Google account.
Click the Add Project button, name it as you like (ours: Djamware) and checks all checkboxes. Finally, click Create Project button then wait a few seconds and click the Continue button. You will be redirected to this page.
Go to Develop menu on the left menu then click Create Database on Cloud Firestore page.
Choose Start in test mode then click Enabled button.
Click Add Collection button to add the new collection for this tutorial. Fill collection ID (ours: ‘boards’) then click next. Add the required fields then click finish the wizard.
Now, the Firebase Firestore Database is ready to access. Make sure that your iOS and Android app match with the configuration files (json/plist). You can get the configuration parameters in the Authentication side menu then you will see the Web Setup button on the top right of the screen.
Install and Create React App
Open the terminal or Node.js command line then go to your React.js projects folder. We will install React.js app creator for creating a React.js app easily. For that, type this create-react-app command.
sudo npm install -g create-react-app
Now, create a React app by type this command.
create-react-app react-firestore
This command will create a new React app with the name react-firestore and this process can take minutes because all dependencies and modules also installing automatically. Next, go to the newly created app folder.
cd ./react-firestore
Now, run the React app for the first time using this command.
npm start
It will automatically open the default browser the point to [http://localhost:3000](http://localhost:3000/ "http://localhost:3000"), so the landing page should be like this.
Install and Configure the Firebase Module
We use Firebase module to access the Firebase Firestore Database. The Firebase module is available as an NPM module. For that, type this command to install the module.
npm install --save firebase
Next, create a new file Firebase.js in the root of the project folder for Firebase configuration.
touch src/Firebase.js
Open and edit src/Firebase.js then replace all codes with this.
import * as firebase from 'firebase';
import firestore from 'firebase/firestore'
const settings = {timestampsInSnapshots: true};
const config = {
apiKey: "YOUR_API_KEY",
authDomain: "YOUR_AUTH_DOMAIN",
databaseURL: "YOUR_DATABASE_URL",
projectId: "YOUR_PROJECT_ID",
storageBucket: "YOUR_STORAGE_BUCKET",
messagingSenderId: "YOUR_MESSAGING_ID"
};
firebase.initializeApp(config);
firebase.firestore().settings(settings);
export default firebase;
You can find or get those configuration parameters by click on Web Setup button in the page authentication of Firebase Console.
Add React Router DOM
Before creating React Router DOM, first, we have to install the required NPM modules including react-router-dom and bootstrap by typing these commands.
npm install --save react-router-dom
npm install --save-dev bootstrap
The React.js CRUD web application required pages to creating, show details and edit Board data. For that, type this commands to create those components.
mkdir src/components
touch src/components/Create.js
touch src/components/Show.js
touch src/components/Edit.js
Next, we will create routes for those components. Open and edit src/index.js then replace all codes with this.
import React from 'react';
import ReactDOM from 'react-dom';
import { BrowserRouter as Router, Route } from 'react-router-dom';
import '../node_modules/bootstrap/dist/css/bootstrap.min.css';
import './index.css';
import App from './App';
import * as serviceWorker from './serviceWorker';
import Edit from './components/Edit';
import Create from './components/Create';
import Show from './components/Show';
ReactDOM.render(
<Router>
<div>
<Route exact path='/' component={App} />
<Route path='/edit/:id' component={Edit} />
<Route path='/create' component={Create} />
<Route path='/show/:id' component={Show} />
</div>
</Router>,
document.getElementById('root')
);
// If you want your app to work offline and load faster, you can change
// unregister() to register() below. Note this comes with some pitfalls.
// Learn more about service workers: http://bit.ly/CRA-PWA
serviceWorker.unregister();
As you see that Edit, Create and Show added as the separate component. Bootstrap also included in the import to make the views better.
Create List of Boards
To show the list of the board in the Board components, open and edit src/App.js then replace all codes with these codes that contain get data from Firebase and display using to React.js template with Bootstrap for styling.
import React, { Component } from 'react';
import { Link } from 'react-router-dom';
import './App.css';
import firebase from './Firebase';
class App extends Component {
constructor(props) {
super(props);
this.ref = firebase.firestore().collection('boards');
this.unsubscribe = null;
this.state = {
boards: []
};
}
onCollectionUpdate = (querySnapshot) => {
const boards = [];
querySnapshot.forEach((doc) => {
const { title, description, author } = doc.data();
boards.push({
key: doc.id,
doc, // DocumentSnapshot
title,
description,
author,
});
});
this.setState({
boards
});
}
componentDidMount() {
this.unsubscribe = this.ref.onSnapshot(this.onCollectionUpdate);
}
render() {
return (
<div class="container">
<div class="panel panel-default">
<div class="panel-heading">
<h3 class="panel-title">
BOARD LIST
</h3>
</div>
<div class="panel-body">
<h4><Link to="/create">Add Board</Link></h4>
<table class="table table-stripe">
<thead>
<tr>
<th>Title</th>
<th>Description</th>
<th>Author</th>
</tr>
</thead>
<tbody>
{this.state.boards.map(board =>
<tr>
<td><Link to={`/show/${board.key}`}>{board.title}</Link></td>
<td>{board.description}</td>
<td>{board.author}</td>
</tr>
)}
</tbody>
</table>
</div>
</div>
</div>
);
}
}
export default App;
Create Show Details and Delete Board
To show board details that listed on the home page, open and edit src/components/Show.js then add these lines of codes contain get data by key or ID from Firebase then display to React.js template with Bootstrap as the style.
import React, { Component } from 'react';
import firebase from '../Firebase';
import { Link } from 'react-router-dom';
class Show extends Component {
constructor(props) {
super(props);
this.state = {
board: {},
key: ''
};
}
componentDidMount() {
const ref = firebase.firestore().collection('boards').doc(this.props.match.params.id);
ref.get().then((doc) => {
if (doc.exists) {
this.setState({
board: doc.data(),
key: doc.id,
isLoading: false
});
} else {
console.log("No such document!");
}
});
}
delete(id){
firebase.firestore().collection('boards').doc(id).delete().then(() => {
console.log("Document successfully deleted!");
this.props.history.push("/")
}).catch((error) => {
console.error("Error removing document: ", error);
});
}
render() {
return (
<div class="container">
<div class="panel panel-default">
<div class="panel-heading">
<h4><Link to="/">Board List</Link></h4>
<h3 class="panel-title">
{this.state.board.title}
</h3>
</div>
<div class="panel-body">
<dl>
<dt>Description:</dt>
<dd>{this.state.board.description}</dd>
<dt>Author:</dt>
<dd>{this.state.board.author}</dd>
</dl>
<Link to={`/edit/${this.state.key}`} class="btn btn-success">Edit</Link>
<button onClick={this.delete.bind(this, this.state.key)} class="btn btn-danger">Delete</button>
</div>
</div>
</div>
);
}
}
export default Show;
Create Add Board
For adding a new board, open and edit src/components/Create.js then replace all codes with these codes.
import React, { Component } from 'react';
import ReactDOM from 'react-dom';
import firebase from '../Firebase';
import { Link } from 'react-router-dom';
class Create extends Component {
constructor() {
super();
this.ref = firebase.firestore().collection('boards');
this.state = {
title: '',

}
onChange = (e) => {
const state = this.state
state[e.target.name] = e.target.value;
this.setState(state);
}
onSubmit = (e) => {
e.preventDefault();
const { title, description, author } = this.state;
this.ref.add({
title,
description,

});
this.props.history.push("/")
})
.catch((error) => {

</form>
</div>
</div>
</div>
);
}
}
export default Create;
Create Edit Board
To edit board, open and edit, src/components/Edit.js then add these lines of codes.
import React, { Component } from 'react';
import firebase from '../Firebase';
import { Link } from 'react-router-dom';
class Edit extends Component {
constructor(props) {

How native is React Native? | React Native vs Native App Development
If you are undertaking a mobile app development for your start-up or enterprise, you are likely wondering whether to use React Native. As a popular development framework, React Native helps you to develop near-native mobile apps. However, you are probably also wondering how close you can get to a native app by using React Native. How native is React Native?
In the article, we discuss the similarities between native mobile development and development using React Native. We also touch upon where they differ and how to bridge the gaps. Read on.
A brief introduction to React Native
Let’s briefly set the context first. We will briefly touch upon what React Native is and how it differs from earlier hybrid frameworks.
React Native is a popular JavaScript framework that Facebook has created. You can use this open-source framework to code natively rendering Android and iOS mobile apps. You can use it to develop web apps too.
Facebook has developed React Native based on React, its JavaScript library. The first release of React Native came in March 2015. At the time of writing this article, the latest stable release of React Native is 0.62.0, and it was released in March 2020.
Although relatively new, React Native has acquired a high degree of popularity. The “Stack Overflow Developer Survey 2019” report identifies it as the 8th most loved framework. Facebook, Walmart, and Bloomberg are some of the top companies that use React Native.
The popularity of React Native comes from its advantages. Some of its advantages are as follows:
- Performance: It delivers optimal performance.
- Cross-platform development: You can develop both Android and iOS apps with it. The reuse of code expedites development and reduces costs.
- UI design: React Native enables you to design simple and responsive UI for your mobile app.
- 3rd party plugins: This framework supports 3rd party plugins.
- Developer community: A vibrant community of developers support React Native.
Why React Native is fundamentally different from earlier hybrid frameworks
Are you wondering whether React Native is just another of those hybrid frameworks like Ionic or Cordova? It’s not! React Native is fundamentally different from these earlier hybrid frameworks.
React Native is very close to native. Consider the following aspects as described on the React Native website:
- Access to many native platforms features: The primitives of React Native render to native platform UI. This means that your React Native app will use many native platform APIs as native apps would do.
- Near-native user experience: React Native provides several native components, and these are platform agnostic.
- The ease of accessing native APIs: React Native uses a declarative UI paradigm. This enables React Native to interact easily with native platform APIs since React Native wraps existing native code.
Due to these factors, React Native offers many more advantages compared to those earlier hybrid frameworks. We now review them.

NBB: Ad-hoc CLJS Scripting on Node.js
Nbb
Not babashka. Node.js babashka!?
Ad-hoc CLJS scripting on Node.js.
Status
Experimental. Please report issues here.
Goals and features
Nbb's main goal is to make it easy to get started with ad hoc CLJS scripting on Node.js.
Additional goals and features are:
- Fast startup without relying on a custom version of Node.js.
- Small artifact (current size is around 1.2MB).
- First class macros.
- Support building small TUI apps using Reagent.
- Complement babashka with libraries from the Node.js ecosystem.
Requirements
Nbb requires Node.js v12 or newer.
How does this tool work?
CLJS code is evaluated through SCI, the same interpreter that powers babashka. Because SCI works with advanced compilation, the bundle size, especially when combined with other dependencies, is smaller than what you get with self-hosted CLJS. That makes startup faster. The trade-off is that execution is less performant and that only a subset of CLJS is available (e.g. no deftype, yet).
Usage
Install nbb from NPM:
$ npm install nbb -g
Omit -g for a local install.
Try out an expression:
$ nbb -e '(+ 1 2 3)'
6
And then install some other NPM libraries to use in the script. E.g.:
$ npm install csv-parse shelljs zx
Create a script which uses the NPM libraries:
(ns script
(:require ["csv-parse/lib/sync$default" :as csv-parse]
["fs" :as fs]
["path" :as path]
["shelljs$default" :as sh]
["term-size$default" :as term-size]
["zx$default" :as zx]
["zx$fs" :as zxfs]
[nbb.core :refer [*file*]]))
(prn (path/resolve "."))
(prn (term-size))
(println (count (str (fs/readFileSync *file*))))
(prn (sh/ls "."))
(prn (csv-parse "foo,bar"))
(prn (zxfs/existsSync *file*))
(zx/$ #js ["ls"])
Call the script:
$ nbb script.cljs
"/private/tmp/test-script"
#js {:columns 216, :rows 47}
510
#js ["node_modules" "package-lock.json" "package.json" "script.cljs"]
#js [#js ["foo" "bar"]]
true
$ ls
node_modules
package-lock.json
package.json
script.cljs
Macros
Nbb has first class support for macros: you can define them right inside your .cljs file, like you are used to from JVM Clojure. Consider the plet macro to make working with promises more palatable:
(defmacro plet
[bindings & body]
(let [binding-pairs (reverse (partition 2 bindings))
body (cons 'do body)]
(reduce (fn [body [sym expr]]
(let [expr (list '.resolve 'js/Promise expr)]
(list '.then expr (list 'clojure.core/fn (vector sym)
body))))
body
binding-pairs)))
Using this macro we can look async code more like sync code. Consider this puppeteer example:
(-> (.launch puppeteer)
(.then (fn [browser]
(-> (.newPage browser)
(.then (fn [page]
(-> (.goto page "https://clojure.org")
(.then #(.screenshot page #js{:path "screenshot.png"}))
(.catch #(js/console.log %))
(.then #(.close browser)))))))))
Using plet this becomes:
(plet [browser (.launch puppeteer)
page (.newPage browser)
_ (.goto page "https://clojure.org")
_ (-> (.screenshot page #js{:path "screenshot.png"})
(.catch #(js/console.log %)))]
(.close browser))
See the puppeteer example for the full code.
Since v0.0.36, nbb includes promesa which is a library to deal with promises. The above plet macro is similar to promesa.core/let.
Startup time
$ time nbb -e '(+ 1 2 3)'
6
nbb -e '(+ 1 2 3)' 0.17s user 0.02s system 109% cpu 0.168 total
The baseline startup time for a script is about 170ms seconds on my laptop. When invoked via npx this adds another 300ms or so, so for faster startup, either use a globally installed nbb or use $(npm bin)/nbb script.cljs to bypass npx.
Dependencies
NPM dependencies
Nbb does not depend on any NPM dependencies. All NPM libraries loaded by a script are resolved relative to that script. When using the Reagent module, React is resolved in the same way as any other NPM library.
Classpath
To load .cljs files from local paths or dependencies, you can use the --classpath argument. The current dir is added to the classpath automatically. So if there is a file foo/bar.cljs relative to your current dir, then you can load it via (:require [foo.bar :as fb]). Note that nbb uses the same naming conventions for namespaces and directories as other Clojure tools: foo-bar in the namespace name becomes foo_bar in the directory name.
To load dependencies from the Clojure ecosystem, you can use the Clojure CLI or babashka to download them and produce a classpath:
$ classpath="$(clojure -A:nbb -Spath -Sdeps '{:aliases {:nbb {:replace-deps {com.github.seancorfield/honeysql {:git/tag "v2.0.0-rc5" :git/sha "01c3a55"}}}}}')"
and then feed it to the --classpath argument:
$ nbb --classpath "$classpath" -e "(require '[honey.sql :as sql]) (sql/format {:select :foo :from :bar :where [:= :baz 2]})"
["SELECT foo FROM bar WHERE baz = ?" 2]
Currently nbb only reads from directories, not jar files, so you are encouraged to use git libs. Support for .jar files will be added later.
Current file
The name of the file that is currently being executed is available via nbb.core/*file* or on the metadata of vars:
(ns foo
(:require [nbb.core :refer [*file*]]))
(prn *file*) ;; "/private/tmp/foo.cljs"
(defn f [])
(prn (:file (meta #'f))) ;; "/private/tmp/foo.cljs"
Reagent
Nbb includes reagent.core which will be lazily loaded when required. You can use this together with ink to create a TUI application:
$ npm install ink
ink-demo.cljs:
(ns ink-demo
(:require ["ink" :refer [render Text]]
[reagent.core :as r]))
(defonce state (r/atom 0))
(doseq [n (range 1 11)]
(js/setTimeout #(swap! state inc) (* n 500)))
(defn hello []
[:> Text {:color "green"} "Hello, world! " @state])
(render (r/as-element [hello]))
Promesa
Working with callbacks and promises can become tedious. Since nbb v0.0.36 the promesa.core namespace is included with the let and do! macros. An example:
(ns prom
(:require [promesa.core :as p]))
(defn sleep [ms]
(js/Promise.
(fn [resolve _]
(js/setTimeout resolve ms))))
(defn do-stuff
[]
(p/do!
(println "Doing stuff which takes a while")
(sleep 1000)
1))
(p/let [a (do-stuff)
b (inc a)
c (do-stuff)
d (+ b c)]
(prn d))
$ nbb prom.cljs
Doing stuff which takes a while
Doing stuff which takes a while
3
Also see API docs.
Js-interop
Since nbb v0.0.75 applied-science/js-interop is available:
(ns example
(:require [applied-science.js-interop :as j]))
(def o (j/lit {:a 1 :b 2 :c {:d 1}}))
(prn (j/select-keys o [:a :b])) ;; #js {:a 1, :b 2}
(prn (j/get-in o [:c :d])) ;; 1
Most of this library is supported in nbb, except the following:
- destructuring using
:syms - property access using
.-xnotation. In nbb, you must use keywords.
See the example of what is currently supported.
Examples
See the examples directory for small examples.
Also check out these projects built with nbb:
- c64core: retrocompute aesthetics twitter bot
- gallery.cljs: script to download walpapers from windowsonearth.org.
- nbb-action-example: example of a Github action built with nbb.
API
See API documentation.
Migrating to shadow-cljs
See this gist on how to convert an nbb script or project to shadow-cljs.

How to Select and Hire the Best React JS and React Native Developers?
Since March 2020 reached 556 million monthly downloads have increased, It shows that React JS has been steadily growing. React.js also provides a desirable amount of pliancy and efficiency for developing innovative solutions with interactive user interfaces. It’s no surprise that an increasing number of businesses are adopting this technology. How do you select and recruit React.js developers who will propel your project forward? How much does a React developer make? We’ll bring you here all the details you need.
What is React.js?
Facebook built and maintains React.js, an open-source JavaScript library for designing development tools. React.js is used to create single-page applications (SPAs) that can be used in conjunction with React Native to develop native cross-platform apps.
React vs React Native
- React Native is a platform that uses a collection of mobile-specific components provided by the React kit, while React.js is a JavaScript-based library.
- React.js and React Native have similar syntax and workflows, but their implementation is quite different.
- React Native is designed to create native mobile apps that are distinct from those created in Objective-C or Java. React, on the other hand, can be used to develop web apps, hybrid and mobile & desktop applications.
- React Native, in essence, takes the same conceptual UI cornerstones as standard iOS and Android apps and assembles them using React.js syntax to create a rich mobile experience.
What is the Average React Developer Salary?
In the United States, the average React developer salary is $94,205 a year, or $30-$48 per hour, This is one of the highest among JavaScript developers. The starting salary for junior React.js developers is $60,510 per year, rising to $112,480 for senior roles.
* React.js Developer Salary by Country
- United States- $120,000
