Create a Live Chat Web Widget Tutorial using Javascript

Simple live chat javascript demo

There's been so many chat widgets out there you can just use. But what if you want to create and manage the entirety of your system by yourself? It's very easy to create another live chat widget on your own.

In today's tutorial, I'm going to show you how to create a live chat using JavaScript and Node.js. The chat will be very simple, allowing you to modify it according to your needs and styles. The main features of our chat will include:

- A page for clients
- A page for the admin that can simultaneously reply to all incoming client chats

We'll begin by setting up the client-side of our chat application. This will be the interface that your users interact with when they visit your site. The HTML file, which we'll call user.html, will contain the basic structure for the chat interface. You can style it to fit the look and feel of your website, adding CSS for visual appeal and JavaScript to handle the interactions.

Next, we'll create an admin interface. This admin page, admin.html, will allow you or your support team to monitor and respond to messages from all your users. The admin page will also have its own HTML structure and JavaScript to manage the incoming and outgoing messages efficiently.

With the client and admin pages set up, we'll move on to the server-side of our application. This is where Node.js comes into play. We'll use Node.js to create a socket server that handles the real-time communication between the clients and the admin. The server will listen for incoming messages from clients and broadcast them to the admin, and vice versa. Create server.js:

We'll set up our server using Express to serve our static files and Socket.io to manage the WebSocket connections. This combination allows for efficient and scalable real-time communication. Our server script will handle events such as new connections, incoming messages, and disconnections.

To get our server up and running, we'll need to install the necessary Node.js packages and configure our server script. Once everything is set up, we can start the server with a simple command.
npm init
npm install ws express
node server.js
For demonstration purposes, you'll want to open the user.html and admin.html pages in two different browsers. This way, you can simulate a conversation between a client and an admin, seeing how messages are sent and received in real-time.

I hope this tutorial will be useful for your own business or web page. Creating your own live chat system that you have complete control over the features and design, allowing you to provide a customized and seamless experience for your users. If you have any questions or need further assistance, feel free to reach out. Happy coding!

Spring Boot is a handy tool that simplifies the development of Spring Framework applications by reducing the need for cumbersome configuration. In this tutorial, I'll guide you through creating a Spring Boot application using the Netbeans IDE. While you can certainly create a Spring Boot application in Netbeans manually, it's much easier with a plugin designed for Spring development. Here's a step-by-step guide to get you started: 1. Install the Spring Boot Plugin: Open Netbeans and navigate to the Tools menu. Click on "Plugins." Once the Plugins window opens, select the "Available Plugins" tab. Look for the "Nb SpringBoot" plugin, then install and activate it. 2. Create a New Spring Boot Project: After restarting Netbeans IDE, you can create a new project with Spring Boot. Go to File > New Project. Under Categories, select Maven, then choose "Spring Boot Basic." 3. Add Dependencies: With your new project created, open the po

Spring Kafka - How to use ReplyingKafkaTemplate send and reply synchronously

Microservice Spring with Apache Kafka Today, I want to share how to use Kafka. It's quite interesting once you get the hang of it, and I hope my explanation will make it a bit easier for you. So, Kafka is primarily known as an asynchronous messaging queuing system. This means it allows different parts of your application to communicate with each other without waiting for immediate responses. However, there are times when you might need a more immediate reply from another service in your project. Luckily, Kafka can handle this too. Here’s how it works: The client side sends a message to the server side via Kafka. This message includes a special identifier in the Kafka header request, known as KafkaHeaders.CORRELATION_ID, along with a topic where the server should respond. The server, after processing the request, sends a message back to the same topic with the same correlation ID. This way, the client knows that the message is a response to its initial request and can act accordingl
