Want to learn how to build web applications? You’ve found the right guide! We’ll explain what web application development is, the different parts of it, what skills you’ll need, and how to get started. Even if you’re a development beginner, this guide will give you the basics to start making your own web apps. We’ll also share web application development tips and resources to help you learn.

What is Web Application Development？

Web application development is the process of making apps that you use in a web browser over the internet. Web apps are not installed on your computer like regular programs. Instead, they are hosted on remote servers and you access them through a website.

The main parts of a web app are:

• The front-end user interface is made with HTML, CSS, and JavaScript that runs in the browser. This is the part you see and interact with.
• The back-end code is made with languages like PHP, Ruby, Python, Java, etc. that run on the server. This handles the behind-the-scenes logic.
• The database that stores and manages data for the app.

To build web apps, web application developers need skills in:

• Front-end coding for the user interface
• Back-end coding for server-side logic
• Databases for storing and managing data

Frameworks like React, Angular, Django, Rails, Spring, and Laravel help speed up web app development. The goal is to build an interactive app that is useful to users over the web with a great experience.

Web apps are very common today – webmail, social networks, streaming, shopping sites, and more are web apps we use daily. With complex features and the need to handle many users, web app development today uses agile methodologies.

What is a Web Application?

A web application is a software program that runs on a web server and is accessed through a web browser over a network such as the Internet or an intranet. Unlike traditional desktop applications, which are launched by your operating system, web apps must be accessed through a web browser. This approach means that web applications do not need to be downloaded or installed on the user’s device; instead, they are accessed and used directly in the browser, which makes them platform-independent and easily accessible from anywhere.

Web applications can range from simple tools like email services and online calculators to complex software systems such as project management tools, social media platforms, and e-commerce sites. They are developed using standard web technologies, including HTML, CSS, and JavaScript, and often involve both frontend and backend components. These components work together to manage the user interface, application logic, and data storage and retrieval. The convenience, ease of updates, and ability to support multiple users simultaneously are key reasons for the growing popularity of web applications.

What is the Difference Between Web Applications and Websites?

Websites and web applications are different. Websites are static, meaning they do not change unless you refresh the page. They typically provide information, such as text, images, and videos. You can click links or fill out forms, but that’s all you can do.

Web applications, on the other hand, are dynamic. They change as you use them, allowing you to do more, such as login, change data, leave comments, and buy things. Webmail, document editors, social media, and shopping sites are all examples of web applications.

Websites and web applications can both look nice, but web applications require more programming behind the scenes to work well. Website design focuses on how the website looks, while web application design focuses on making the features work using databases and servers.

In short, websites provide static information, while web applications make that information interactive. If you just need information, use a website. If you need to interact with data, use a web application. They both have important roles in our online experiences.
