Making #ReactJS Realtime With #Websockets

  • Installation – Now, install create-react-app and also scaffold a new React app with the following commands: – npm install -g create-react-app – – create-react-app react-pusher – – Once all the necessary files are installed, change directory into react-“pusher and start the application with: – npm start – – By now,…
  • There are number of dependencies required for the application server, so let’s install them immediately: – npm install –save axios body-parser cors express pusher pusher-js – – To configure the entry point of the application, create a file called server.js and paste the code below into it: – const Pusher…
  • /ChatBox.css’; – export default ({ text, username, handleTextChange }) = ( – div – div className=”row” – div className=”col-xs-12″ – div className=”chat” – div className=”col-xs-5 col-xs-offset-3″ – input – type=”text” – value={text} – placeholder=”chat here…” – className=”form-control” – onChange={handleTextChange} – onKeyDown={handleTextChange} – / – /div – div className=”clearfix”/div – /div…
  • /avatar.png”; – export default ({ chats }) = ( – ul – {chats.map(chat = { – return ( – div – div className=”row show-grid” – div className=”col-xs-12″ – – div className=”chatMessage” – div key={chat.id} className=”box” – p – strong{chat.username}/strong – /p – p{chat.message}/p – /div – div className=”imageHolder” – img…
  • The state variables in the app are created and defined in the constructor like this: – … – class App extends Component { – constructor(props) { – super(props); – this.state = { – text: ”, – username: ”, – chats: [] – }; – } – componentDidMount() { – ……

This quick tutorial will lead you through building a basic, realtime group chat app, similar to our demo here…

Every chat application requires real time functionality. This amongst other benefits allows interaction between users in different location(s). A chat application like this can be built to function on diverse platforms, be it mobile or web applications.

In this tutorial, I will be showing you how to build a chat application using React and Pusher. This is a very simple application and it comes with functionality which will be showing some of the rich features of Pusher and how you can easily combine it with a modern library like React.

Pusher is a platform that allows developers to easily build an application with realtime features as quickly as possible. Pusher specialises in building realtime and scalable infrastructures for developers and is packaged with powerful features like client events, queryable API, Pub/Sub messaging and others.

We will explore Pusher as we proceed in this tutorial and leverage on the DOM manipulation, event driven and data-binding ability of React.

A basic knowledge of JavaScript and React will be of advantage so as to effectively participate in this tutorial.

A sneak peek into what we will build in this tutorial:

Getting Started

For a hitch-free flow of procedures in this tutorial, we will begin by setting up the required credentials with Pusher. If you don’t have an account, kindly create one . Once you are done, go ahead and create a new app from your dashboard….
