Having recently worked with young web developers who were exposed for the first time to proper production infrastructure, I received many questions about the various components that one can find in the architecture of a “Web service”. These questions clearly expressed the
confusion (and sometimes the frustration) of developers who understand how to create endpoints in a high-level language such as Node.js or Python, but were never introduced to the complexity of what happens between the user’s browser and their framework of choice. Most of the time they don’t know why the framework itself is there in the first place.
The challenge is clear if we just list (in random order), some of the words we use when we discuss (Python) Web development: HTTP, cookies, web server, Websockets, FTP, multi-threaded, reverse proxy, Django, nginx, static files, POST, certificates, framework, Flask, SSL, GET, WSGI, session management, TLS, load balancing, Apache.
In this post, I want to review all the words mentioned above (and a couple more) trying to build a production-ready web service from the ground up. I hope this might help young developers to get the whole picture and to make sense of these “obscure” names that senior developers like me tend to drop in everyday conversations (sometimes arguably out of turn).
As the focus of the post is the global architecture and the reasons behind the presence of specific components, the example service I will use will be a basic HTML web page. The reference language will be Python but the overall discussion applies to any language or framework.
My approach will be that of first stating the rationale and then implementing a possible solution. After this, I will point out missing pieces or unresolved issues and move on with the next layer. At the end of the process, the reader should have a clear picture of why each component has been added to the system.

I consider myself an active StackOverflow user, despite my activity tends to vary depending on my daily workload. I enjoy answering questions with angular tag and I always try to create some working example to prove correctness of my answers.
To create angular demo I usually use either plunker or stackblitz or even jsfiddle. I like all of them but when I run into some errors I want to have a little bit more usable tool to undestand what’s going on.
Many people who ask questions on stackoverflow don’t want to isolate the problem and prepare minimal reproduction so they usually post all code to their questions on SO. They also tend to be not accurate and make a lot of mistakes in template syntax. To not waste a lot of time investigating where the error comes from I tried to create a tool that will help me to quickly find what causes the problem.

Let me show what I mean…
There are template parser errors that can be easy catched by stackblitz

Last decade has seen introduction of lot of new software development framework and technologies. The purpose behind creating these frameworks is to serve the need of growing demand for web and mobile applications around the world.MEAN stack is one of these latest tools for web based software development.
What is Mean stack?
MEAN Stack development is basically a composition for MongoDB, Express js, angular.js and node.js. MEAN stack some time uses react.js and to form MERN stack.Let’s look at each component in more details.
Mongo DB: MongoDB is an open-source NoSQL database that will hold all of the application’s data. It allows developers to quickly change the structure of the data is persisted. Here it relies on an architecture that comprises of collection & documents and not table & rows.
Express JS: It is used to create web application easily. Also provides a slight simplification for creating a request to developer procedure. This way it gets easier to write modules, secure & fast applications.
Benefits of MEAN Stack Development
Server and Client switch was never this easy
Multipurpose and Flexible
MEAN stack is truly wonderful and offers greater flexibility with development to developers. The framework allows for easy testing of the app on the cloud platform upon completing the development process. The development, testing and introduction into the cloud processes are done seamlessly. Any additional information can also be incorporated into the app by simply adding an extra filed on to the form. The technology responsible for this feature is MongoDB which, because it is specifically tailored for the cloud, offers automatic replication and full cluster support.
Build MVP quickly
MVP stands for a minimum viable product. It comprises to the app developed with the most basic and essential features. This set of features are the bare minimum of what users are searching for in a product. Being able to develop an MVP in the shortest time possible is critical for cutting costs as well as testing the product in the market. The MEAN stack makes it possible to create an MVP quickly because the framework offers fast development.
MEAN / MERN allows Isomorphic coding possible
There are two major OS platforms on which mobile operators, namely: iOS and Android. Anyone interested in creating an app for both platforms needs to do a separate project for each. But with the MEAN / MERN stack, this is not necessary. Apps developed using MEAN /MERN are isomorphic, meaning that they can work on multiple platforms without having to change the base code. Thus, the developer’s work is cut in half and more time is spent on enhancing the app already created. Businesses aiming to reach a wider market segment will therefore benefit from using the stack.
Ease in Development with Single Programming Language
Responsive and Time-saving
If you need to develop an application with limited timelines, use MEAN stack to achieve that. It has infinite module libraries for node Js, which are ready for use. As a result this aspect saves your time and initially used to create modules from scratch. It also has an automated testing feature that instantly notifies you when a particular feature is broken. It gives you more time to polish your project to perfection.
Some of the benefits outlined above are just a little of what the company stands to gain in incorporating the MEAN stack in their app development projects. Enhanced app quality, reduced costs, and time for app development and also which to save time and money, or are just interested in managing a business.

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. Web design and web development go hand-in-hand and the need for a professional web design and development company, offering a blend of creative designs and user-centric elements at an affordable rate, is growing at a significant rate.
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.

It is obvious that before starting any web development project, choosing the best technology is one of the major concerns. Today, different technologies are being used for mobile application development. So, reading about those technologies in this blog is our motive.
Here, in this blog, I am going to make a decision about which technology is the best if we have the choices like Full-Stack vs MEAN stack vs MERN Stack.
Let’s discuss all these terms individually and one by one with their advantages and disadvantages. So let’s have a quick look:
Stack means a data type which acts as a collection of components which is having two main functions. The one is push which helps in adding components to the collection. Another is pop which helps in removing the recently added component that was not yet removed.
