Let’s Build a Real-Time Chat Application using Socket.IO, React, Node.js and MongoDB

Why web sockets?

As the web evolves, so do the technologies that power it. Although RESThas remained the default choice for web services architectures, most modern applications require features that REST would not be able to reliably provide. These features have one thing in common, real-time. Whether it is a notification system, a chat-box, or an activity tracker, a constant stream of information is required. This is exactly where sockets shine, being able to send data back and forth without having to re-initialize a connection for each action. One of the best libraries for handling web sockets is Socket.IO.

The stack

We will be using React for the front-end and Node.js for the back-end, Express as the web framework, MongoDB as database and Mongoose as ODM. We will then be able to connect the two ends using Socket.IOamazing API.

I will assume that you have already installed the latest version of Node.js, as well as the specific MongoDB distribution for your own OS. Or, you can simply use Atlas.

Project structure

Let’s go ahead and make a new folder, chat-demo/. Inside of it we can create two sub-folders: frontend/ and backend/, which will contain their respective source code:

You can name the folders however you’d like, of course.

Setting up React

We will create a new React application using create-react-app. Type the following command inside the frontend/ folder:

$ npx create-react-app .

We can remove a few files that we do not need.

Inside public/, let’s delete everything except index.html.

Inside src/, delete everything except App.js, index.css and index.js.

Deleting said files is not mandatory either, but will leave us with a cleaner structure.

Creating our chat component

First of all, let’s install the socket.io-client package by typing the following command inside the_ frontend/_ folder:

$ npm i socket.io-client

We can now write our chat component inside App.js.

import React, { useState, useEffect } from "react";

	import socketIoClient from "socket.io-client";

	const socket = socketIoClient("http://localhost:8463", { autoConnect: false });

	const Message = ({ msg }) => {

	    return (
	        <div className="msg">
	            <span> { new Date(msg.date).toLocaleDateString() } </span>
	            <span> { msg.content } </span>
	        </div>
	    );

	};

	const MessageBox = () => {

	    const [value, setValue] = useState("");

	    const postMessage = e => {
	        e.preventDefault();

	        if (!value) return;

	        socket.emit("message", value);

	        setValue("");
	    };

	    return (
	        <form onSubmit={ postMessage }>
	            <input type="text" className="input" placeholder="message"
	                   value={ value } onChange={ e => setValue(e.target.value) }
	            />
	        </form>
	    );

	};

	const Chat = () => {

	    const [messages, setMessages] = useState([]);

	    const addMessage = (msg) => {
	        setMessages(oldMessages => [...oldMessages, ...(Array.isArray(msg) ? msg.reverse() : [msg])]);
	    };

	    useEffect(()=> {

	        socket.on("latest", (data) => {
	            // expect server to send us the latest messages
	            addMessage(data);
	        });
	        socket.on("message", (msg) => {
	            addMessage(msg);
	        });

	        socket.connect();

	    }, []);

	    return (
	        <div>
	            <div id = "msgBox">
	                { messages.map((msg, index) => <Message msg={msg} />) }
	            </div>
	            <MessageBox />
	        </div>
	    );

	};

	export default Chat;

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.
