In today's blog we are going to talk about what is web development and why shall we learn web development. Get ready to begin our journey in the world of web development. Let's get started by understanding what is web development.

What is web development?

Web development is the process of building a website, right from designing to implementing to maintaining it. The end result of a web development process has changed considerably in the past few decades. The advent of web development began with a collection of static web pages. The static websites then advanced to interactive websites that are capable of storing, manipulating and accessing user data. Now, we have dynamic websites that are customised for every user with the help of AI and machine learning.

Web development consists of various parts that are undertaken by different developers. We would comprehend each part in the chronological order i.e. the order in which they appear first. The first in our list would be the front end.

Front end in Web development

The front end is basically a visual experience for the user. It is also known as client-side development. The objective of building a front-end is 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 customized websites. The HTML language is made up of tags that are used to build web pages from scratch.

  2. CSS

    Cascading style sheets, popularly known as CSS, are used for styling web pages. CSS describes the presentation of a document written in a markup language, for example HTML.

    CSS lets the user add fonts, spacing and much more. It’s basically a simple design language. CSS is a very vast topic; it covers various topics and sub-themes that need to be comprehensively covered in order to make and add an effective design on the websites.

    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 an object-oriented programming language used for creating interactive web pages. Javascript is an event-driven, functional and imperative language. It is popularly used to make dynamic effects on web pages like rollover, rollout and other interesting functionalities.

    Javascript was initially used for browsers and web pages but now it has diversified and has moved to other environments and applications also. We will talk about Javascript as a server side language when we understand the backend.

    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.

    React is the most popular framework amongst all. Let’s dive deep and understand what is React.

    Reactjs, essentially a javascript library. It is used to build fast and interactive user interfaces for web and mobile applications. React is an open source library, developers can easily access the source code and modify it according to their application. For understanding it better, React is the ‘view’ part of a MVC (model view controller) model, as it is responsible for what the application looks like.

    React lets you easily build dynamic web applications with enhanced performance. React is easier to learn as compared to other frameworks. There are a number of recent developments like the latest extension in React like React Native which can be used to cross compatible mobile applications.

Back end in Web development

The back end is the part of web application that handles all the important functioning that is hidden from the user. It refers to the development activities on the server side 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 which now stands for Hypertext processor is basically a server-side programming language that runs on almost all platforms and is compatible with all servers6. It is usually used in developing webpages and applications. It is embedded in markup languages like HTML.

    PHP was created by Ramsum Lerdorf in 1994.

    Some important functions of PHP are -

    • PHP is popularly used to create dynamic content on webpages.
    • It collects data from forms that would be filled by users.
    • PHP can access and edit the database
    • PHP can edit and use files on the server

    PHP is an important language that is used on the server-side in web development projects. PHP is used as a part of a technological stack along with HTML, CSS, Javascript and other web languages to build applications.

    PHP is at its core a lightweight scripting language. It has frameworks and CMS like WordPress, Drupal and others. It makes application development simpler and more efficient. It's a portable solution and also easy to deploy compared to other computing languages. However, PHP has a slow response method as it again initialises the application every time after each request.

  2. Nodejs

    Nodejs is a powerful Javascript framework used to develop

    • server-side applications
    • networking applications in distributed systems
    • real-time web applications
    • ones interacting with hardware
    • and other common purpose software.

    Applications built with the help of Nodejs are fast and highly scalable. Nodejs can generate dynamic content on webpages, it can collect data produced through forms and add, delete or modify the database you are using in your project.

    Basically, it is open source and provides a runtime environment for Javascript. With the advent of Nodejs and other frameworks, the demand and popularity of Javascript as a server-side language has exponentially increased.

    Nodejs is asynchronous and event-based and allows you to create fully advanced applications from scratch. Nodejs also has a large set of modules to aid with your development process. Allows advanced and customised request handling. It also supports efficient package managers like NPM and YARN.

    Apart from the languages, there are some popular frameworks for backend also. Some of the most popular backend frameworks are Flask, Laravel, ASP.NET. To get an overview of backend frameworks, let’s understand Express in detail.

    An elementary definition of Express is a ‘web framework for Node JS.’ Major features of Express is a debugging mechanism, template engines, handling HTTP requests and much more. The Express encompasses in itself numerous features that aid developers. To get a hang of this amazing framework, it is essential to understand Express in Node JS in a more detailed manner.

    Express is fast, unopinionated and minimalist. The framework delivers high performance and fast delivery. The framework has features of web applications but that doesn’t mean Node JS is neglected. Express is like a layer of an additional and cool set of features built on top of Node JS.

    Now that we have understood the backend and the front end in detail, let’s get to the point and comprehend the importance of web development and why should we learn web development?
