Some time ago, MuleSoft introduced Web Socket Connector. In this article, I briefly describe what web socket gives us in the context of integration. The main focus of the article is to show you how to publish a web socket for your consumers.
So the first question is what a web socket is. Web socket is a communication protocol over TCP that enables bidirectional communication between client and server.
WebSocket vs HTTP communication
As you can see in the diagram above, the client initiate connection over WebSocketor secure WebSocket (**wss), **and then the server can send back messages to the client. Unline with HTTP protocol we do not need to do any pulling. Once the connection is established, the server can send as many requests as it likes.
The greatest benefit of using Web Socket instead of HTTP is performance boost as we do not need to establish a new connection. What is more, we do not need to introduce any sort of pulling mechanism.
We want to consume forex exchange rates and display them on our banking portal. As they are changing rapidly, we would like to keep values up to date. I have decided to expose WebSocket endpoint to stream changes to the client.
MuleSoft case with published WebSocket endpoint
MuleSoft best practice is API-led connectivity. As a result, in our case, we have three layers. We have Banking Portal Experience API (XAPI), Banking Process API (PAPI) and Banking Forex System API (SAPI). In order to make the data flow smoothly, we will use Amazon SQS queues to exchanged data between layers – as in the diagram above.
Our system API reads exchange rates and publishes them to exchange-rates-sapi queue. Banking Process API reads values from this queue and saves them to exchange-rates-papi queue. This queue will be read by the application in the Experience layer. The Banking Portal XAPI broadcast exchange rates to open web sockets.
When the client initiates a web socket connection, it must decide the primary currency. In other words, if exchange rates should be calculated against USD, EUR, PLN currencies.
WebSocket configuration requires **HTTP Listener **config. In the picture below, you can see that we have to assign existing HTTP_Listener_config to WebSocket configuration by **Listener config **property.
WebSocket global configuration
You can specify how long the connection should be kept while idle. In my scenario, I have decided to kill the connection after 60 minutes.
In order to expose WebSocket connection we have two listeners.
**On New Inbound Connection **is triggered when the client initiates the connection. Below you can see sample JavaScrip line that performs this action. In this case, you don’t have any payload, but you receive the headers/metadata.
var ws = new WebSocket("ws://localhost:8081/ws/exchange-rates");
On New Inbound Message is triggered when the client sends the message on already establish WebSocket connection. The client can send a body that Mule saves within the payload – like JSON. In this part, we often subscribe to some events like chat entries entered by all the users or exchange rate changes. We can also send a message back to the client if we like.
In the JavsScript code snippet below, you can find sending the message to WebSocket.

The term web design simply encompasses a design process related to the front-end design of website that includes writing mark-up. Creative web design has a considerable impact on your perceived business credibility and quality. It taps onto the broader scopes of web development services.
Web designing is identified as a critical factor for the success of websites and eCommerce. The internet has completely changed the way businesses and brands operate.

In this blog, we have focused on the different areas of designing a website that covers all the trends, tools, and techniques coming up with time.
In 2020 itself, the number of smartphone users across the globe stands at 6.95 billion, with experts suggesting a high rise of 17.75 billion by 2024. On the other hand, the percentage of Gen Z web and internet users worldwide is up to 98%. This is not just a huge market but a ginormous one to boost your business and grow your presence online.
Web Design History
At a huge particle physics laboratory, CERN in Switzerland, the son of computer scientist Barner Lee published the first-ever website on August 6, 1991. He is not only the first web designer but also the creator of HTML (HyperText Markup Language). The worldwide web persisted and after two years, the world’s first search engine was born. This was just the beginning.
Evolution of Web Design over the years
With the release of the Internet web browser and Windows 95 in 1995, most trading companies at that time saw innumerable possibilities of instant worldwide information and public sharing of websites to increase their sales. This led to the prospect of eCommerce and worldwide group communications.
The next few years saw a soaring launch of the now-so-famous websites such as Yahoo, Amazon, eBay, Google, and substantially more. In 2004, by the time Facebook was launched, there were more than 50 million websites online.
Then came the era of Google, the ruler of all search engines introducing us to search engine optimization (SEO) and businesses sought their ways to improve their ranks. The world turned more towards mobile web experiences and responsive mobile-friendly web designs became requisite.
Let’s take a deep look at the evolution of illustrious brands to have a profound understanding of web design.
Here is a retrospection of a few widely acclaimed brands over the years.
From a simple idea of renting DVDs online to a multi-billion-dollar business, saying that Netflix has come a long way is an understatement. A company that has sent shockwaves across Hollywood in the form of content delivery. Abundantly, Netflix (NFLX) is responsible for the rise in streaming services across 190 countries and meaningful changes in the entertainment industry.
The idea of Netflix was born when Reed Hastings and Marc Randolph decided to rent DVDs by mail. With 925 titles and a pay-per-rental model, Netflix.com debuts the first DVD rental and sales site with all novel features. It offered unlimited rentals without due dates or monthly rental limitations with a personalized movie recommendation system.
Announcing its initial public offering (IPO) under the NASDAQ ticker NFLX, Netflix reached over 1 million subscribers in the United States by introducing a profile feature in their influential website design along with a free trial allowing members to create lists and rate their favorite movies. The user experience was quite engaging with the categorization of content, recommendations based on history, search engine, and a queue of movies to watch.
Netflix 2001-2005 -2003
They then unleashed streaming and partnering with electronic brands such as blu-ray, Xbox, and set-top boxes so that users can watch series and films straight away. Later in 2010, they also launched their sophisticated website on mobile devices with its iconic red and black themed background.
Netflix 2006-2010 -2007
In 2013, an eye-tracking test revealed that the users didn’t focus on the details of the movie or show in the existing interface and were perplexed with the flow of information. Hence, the professional web designers simply shifted the text from the right side to the top of the screen. With Daredevil, an audio description feature was also launched for the visually impaired ones.
These years, Netflix came with a plethora of new features for their modern website design such as AutoPay, snippets of trailers, recommendations categorized by genre, percentage based on user experience, upcoming shows, top 10 lists, etc. These web application features yielded better results in visual hierarchy and flow of information across the website.
With a sleek logo in their iconic red N, timeless black background with a ‘Watch anywhere, Cancel anytime’ the color, the combination, the statement, and the leading ott platform for top video streaming service Netflix has overgrown into a revolutionary lifestyle of Netflix and Chill.
