Be proud of choosing Node.js as part of your Real-Time Application Development strategy in future projects.
At the dawn of the 21st Century, the web development industry experienced rapid expansion. While much emphasis was put on improving user interfaces and interactive features while speeding up applications and utilities, developers must ultimately prioritize saving time over improving these elements - this has now become their goal and benchmark of development success.
It is crucial that real-time applications such as instant messaging services, notifications of streamed live applications, or instant messenger services operate in real-time to meet users' demands for new updates; instant messaging apps work perfectly.
Whatsapp Messenger, Facebook Messenger, and others are daily messaging applications we rely on. Real-time apps serve numerous other functions; delivery apps, payment apps, or gaming applications could all come under their remit.
Developers use various languages for real-time app creation, including Java, Kotlin, and Angularjs; however, this article will focus on Node.js as it has emerged as an essential technology. Node.js is an open-source, event-driven language with asynchronous features, making it perfect for real-time development applications.
We will build a chat application as part of our demonstration of Node.js for real-time application development. Though explicitly tailored for our demonstration purpose, many concepts used during its creation could apply elsewhere.
Real-time applications can be beneficial when the user doesn't need to refresh their page every few seconds for new data to arrive.
WebSocket provides developers with an effective protocol for communication that both client and server can initiate to achieve real-time applications. At any moment, the server sends data directly from its database to clients without them needing to request it first.
WebSocket API can be used to build applications using WebSockets. When programming with Node.js, you may prefer Socket.io API as it offers more straightforward functionality than its WebSocket counterparts.
Once we've covered some of the fundamental requirements for creating real-time applications, we will move on to developing a chat application. A chat room provides users with an environment in which they can connect in any number and share messages across platforms simultaneously.
As per our requirements, the following features will also be implemented in the application: users can modify their Username, send and receive messages through chat, and see whether another user is typing real-time letters into real-time notifications.
Let's move ahead with building it now that we understand our requirements. Before getting down to business with node.js app development, we must establish the Application Environment.
Create a folder dedicated to our application; run npm for package.json creation; set app.js as the main script, etc.
Nodemon, express, and EJS packages will be utilized when developing our application. Nodemon provides for rapid development as changes made are instantly integrated into the app without needing to restart; Node.io allows quick development with changes implemented without restarts being necessary so that it can speed development considerably; the following command will install socket.io express and eggs, respectively.
Next, it will be necessary to create the structure for your application. This involves creating several directories and app.js files to form your system.
In this way, your app should look something similar to this:
This directory holds assets like CSS, images, and JavaScript (for client-side).
Launch sockets.io by editing app.js and copy/pasting this code below into it, using this coding style for optimal results.
Next, we must initialize socket.io using Express; to achieve this, we must create an event via io. On (), that triggers each time someone connects using socket.io. We will also learn to access servers via socket events while emitting and catching events to complete front-end development.
messageBtn represents our message-sending button, while usernameBtn represents user registration. Inputs contain IDs for both inputs.
Message lists display all user messages; they appear within the class information div when someone types something into them directly.
It needs to connect to our server to make our front end work. For this, in both the JS directories of public libraries and JavaScript files, we must execute this code to connect it.
Once complete, this socket should join, and the front end can begin functioning.
Every new user's default username will be "Anonymous." We will now develop the backend to change it when the front-end triggers "change_username." Add this code below into the Connection Event in the app.js file app.
First, we must modify the Front End so that clicking any of the buttons emits an event with the name "change_username" onto our server.
We do this by attaching an event listener for this event in usernameBtn in chatroom.js, so when a User changes and their page reloads, it automatically changes with their new Username.
Sending messages is the next feature to develop. The front end emits a new message event, and we must pass this on to clients so that they may receive it.
We will configure our Front end so it sends message_new events whenever a client submits one and shows received_message events on the front end as per client configuration requirements; paste the below code into the connect function of chatroom.js for this functionality.
At events, we modify the DOM to display messages. After receiving new_messages in our backend system, an event must be sent out using the io.sockets.emit()function; for that purpose, we need a connect part in app.js to implement our plan of sending new_messages out across users.
Once our sending feature has been completed, we can move on to developing other features of this application.
Including this feature in your application will make the experience look more lifelike. To implement, this requires that the message box emits a typing event whenever the keyboard is pressed - this tells the server when someone is typing; the client side also listens for organizing events to determine who is typing.
Add this code below into chatroom.js' connect function to make this feature effective.
When users enter messages into the message box, we use code to configure our backend to handle these events properly.
Socket.io will notify users as soon as someone types out a message in it; these notifications go out immediately without exception to whoever entered it first.
