 Difference between front end and backend development.

Every organization or even an individual is dependent on the world wide web to showcase their skills or augment their business on a global level. The market for web development has significantly grown in the last few decades. The growing demand for interactive and dynamic websites has increased the value of skilled web developers across the globe. There are opportunities for front-end, back-end and also full stack developers in high-end companies, start-ups and even as freelancers.

In today's time, we visit websites and web applications on a daily basis. From shopping to searching, everything is available on the world wide web as a website. Fun fact, you are reading this blog too on a website. Websites have become an important part of the IT industry because they are considered to be the most innovative and cost-effective way to mark your presence on the world wide web. Every one relies on a personalised space on the web to build an audience.

Coming to the technical part, a website is made up of several programming languages. The architecture of web development can be seen separately as front end and backend. In today's blog we are going to talk about the difference between front and backend web development.

Front end Vs Backend

Over the years, the technology stack for web development has also significantly changed. There is an advent of a number of frameworks, libraries and tools. With the help of these latest inventions in the world of web development, developers are able to build interactive and dynamic websites easily and in a more efficient manner.

The interactive and dynamic websites you visit aren't as simple as they look. They are made up of several layers of programming that work in coordination with each other. In a typical website, there is a clear distinction between what is displayed to the user and what goes behind the scenes. They are called the front end or client side and the backend or the server side respectively.

The main difference between front end and backend is rendering. To understand this rendering, we need to first comprehend the meaning of rendering.

In the simplest terms, rendering means generating output. When we talk in respect to web development, rendering means generating HTML content. HTML is a popular mark-up language used in front end. (We would talk in detail about HTML later in the same article.) Rendering of a website can happen both at front end and on the server. Let's discuss server-side rendering and client side rendering separately.

Server-side rendering

Client-side rendering refers to a technique where the processes are done at a remote server where the requested website is hosted. This means that all the processes required in creating an HTML page that your web browser can understand are handled on a remote server. The processes include querying databases for information or processing any logic that your web application requires.

In client-side rendering, the remote server is busy executing the steps to render the requested website and the client's web browser is idle at that time. It is waiting for the server to finish processing the request and sending a response. When the response is received, web browsers interpret it and display the content on the user's screen.

Client-side rendering

Client-side rendering refers to the technique in which the rendering of the content happens on the client's end and not on the web server. It means that a server is only needed to serve the raw web application. The browser will be in charge of rendering this application in its final form. In simple terms, client-side rendering is entirely rendered on the browser.

Earlier, server-side rendering was the only way to create websites and web applications. The process was as explained above, once a user visits a web page and sends a request for content, the server processes this request and creates a response that is sent back to the client's browser and displayed as front end.

With recent advancement like JavaScript libraries such as Angular, React and Vuea, new form of site rendering emerged called client-side rendering. The server site rendering we talked about is also known as backend development and the client site rendering is front end development.

Now that we know the basic difference between front end and backend development, let's discuss each of them in detail so that the picture is clearer.

Front end Development

The front end is basically the user interface. As mentioned earlier, it is also known as client-side development. The objective of building a front-end is to display the information to the user. Over the years, front end development has advanced and It has become a creative way to attract a large audience and display as much information in a concise way.

There are various tools, frameworks, libraries and technologies that are used to build the front-end but the most popular amongst them is HTML, CSS and Javascript.

  1. HTML

    The HyperText Mark-Up Language, also known as HTML is a mark-up language that is used to build structure of web pages. The HTML language is made up of tags that are used to build web pages from scratch. HTML5 is the latest version of HTML that is being used in the industry.

  2. CSS

    CSS is an acronym for Cascading style sheets. It is basically used for styling web pages. CSS describes how a document would be presented to the user. It covers things like background, color, font etc. It is used to style documents written in a markup language, for example HTML. It’s basically a simple design language. CSS defines the style of an HTML webpage. It describes the behaviour, position and style of all HTML elements. CSS is also responsible for the layout of the webpage.

  3. Javascript

    JavaScript is basically used to make websites interactive. It is an object-oriented programming language used in the front end development. Javascript is an event-driven, functional and imperative language that lets the user add dynamic effects on web pages like rollover, rollout and other interesting functionalities.

    There are a number of Javascript libraries and frameworks that are used to build interactive user experiences easily. Some of them are React, Angular, Vue etc.

    Front end development is an interesting field. You get a chance to express yourself creatively, play with code and build easy experiences for users across the globe. If you see yourself as a successful front-end developer and if you are trying to grab a job as a front developer. This article might help you grab one.

Backend Development?

The backend is the part of web application that handles all the important functions that is essential for the working of an interactive and dynamic website. All functions that constitute the backend are hidden from the user. It refers to the activities that take place on the server and hence it also known as server-side development. In simpler terms, when a user performs any action or triggers any request on the website, the activities that take place behind the scenes are termed as backend development. Backend development mainly consists of – web servers, applications and databases.

The languages popularly used in server-side development are PHP and Nodejs (framework for javascript)

  1. PHP

    PHP created by Ramsum Lerdorf in 1994 now stands for Hypertext processor. It is basically a server-side programming language that runs on almost all platforms and is compatible with all servers. It is usually used in developing webpages and applications. PHP is popularly used to create dynamic content on webpages. PHP can access and edit the database and it can also edit and use files on the server. PHP is used as a part of a technological stack along with HTML, CSS, Javascript and other web languages to build applications.

  2. Nodejs

    Nodejs is basically a Javascript framework which is used to build fast and highly scalable applications. The advent of Nodejs as an open source runtime environment for Javascript has made it possible for Javascript to be used in backend development.

    Nodejs can collect data produced through forms and add, delete or modify the database you are using in your project and hence Nodejs can be used to generate dynamic content on webpages. With the advent of Nodejs and other frameworks, the demand and popularity of Javascript as a server-side language has exponentially increased.
