A Beginners Guide to Web Application Development (2023)
Web application development is a specialized area of software engineering focused on building dynamic, interactive applications that run in a web browser. Unlike traditional desktop applications, web apps are accessible from anywhere, provided you have an internet connection, which makes them incredibly versatile and widely used in today's digital landscape.
In this article, we will provide a comprehensive understanding of web application development, including how to build a web app, reasons to develop a web application, and the frameworks involved. We will also discuss the difference between a Web App and a Web Page and the examples of web applications.
What is Web Application Development?
Web application development is a specialized field within software engineering that concentrates on building web applications. Unlike traditional software development, Web application development is the process involved in building a web application.
Typical steps in the web application development process include defining the problem, creating mock-ups for the solution, engaging with users for feedback, selecting a development framework or tool, and finally, building and testing the web application. This process is often iterative, allowing for adjustments based on user input.
What is the Difference Between a Web App and a Web Page?
What is a Web Application?
On the other hand, the back-end can be built using various programming stacks like LAMP (Linux, Apache, MySQL, PHP) or MEAN (MongoDB, Express.js, Angular, Node.js). Unlike mobile apps, which often require a specific Software Development Kit (SDK), web applications do not have such restrictions.
Web applications gained significant traction alongside the rise of Software as a Service (SaaS) models, where applications are hosted on a cloud and are accessible via the internet.
Google Apps like Google Drive and Google Sheets, Amazon's shopping platform, and YouTube are all examples of web applications.
What is a Website?
In contrast, a website is a collection of interlinked web pages under a single domain name. Individuals, businesses, or organizations can create and maintain these for various purposes, from informational to commercial. Unlike web apps, websites are usually less interactive and may not require user login for access.
Websites are hosted on one or more web servers, and they can be accessed through a network using IP addresses, either via the Internet or a private Local Area Network (LAN).
A restaurant website where you can view the menu, read customer reviews, and find information on opening and closing hours is a good example of a website.
Examples of Web Applications
Here are some real-world examples of web applications and how they serve distinct purposes:
Spotify is a music streaming service that caters to various user needs. It allows users to listen to music on demand, curate their playlists, and discover new artists. One of its standout features is the ability to provide customized playlists curated based on user preferences, listening history, and even geographical location.
Dropbox is a file hosting service focusing on cloud storage, backup, and synchronization. It offers the flexibility to access your files from any device and enables easy file and folder sharing with others. It's an excellent example of how web-based application development can simplify once cumbersome tasks like data storage and sharing.
3. Google Maps
This mapping and navigation service offers real-time traffic updates, route optimization, and driving directions. It's a tool for individuals and allows businesses to manage their location data and analyze customer behavior. Google Maps is a prime example of how web application building can offer dynamic and interactive features.
Netflix is an on-demand streaming service that lets you watch TV shows, movies, and documentaries. Its recommendation engine, powered by machine learning algorithms, sets it apart. Based on your viewing history and preferences, it suggests content you are likely to enjoy, making the user experience highly personalized.
LinkedIn is a professional networking platform that goes beyond just connecting colleagues. Users can set up profiles, discover career opportunities, and access many resources for professional growth, like courses, publications, and various tools. The platform showcases how web apps can serve multiple functionalities, from networking to education.
Zoom became especially relevant during the COVID-19 pandemic as a video conferencing tool, but it has features that extend beyond just video calls. It offers screen sharing, virtual backgrounds, and breakout rooms, making it an indispensable tool for remote work and study.
Why Develop a Web Application?
Creating a web application is good for people and companies in many ways:
1. Reach More People
One of the biggest benefits of web apps is their ability to be accessed on any device with an internet connection. Unlike platform-specific native apps, a web app is universally accessible, allowing you to reach a wider audience.
2. Cost-Effective Development
Developing a web app can often be more cost-effective than creating native apps for individual platforms like Android or iOS. This is because web apps allow for the development of a single codebase that can run on multiple devices, thereby saving both time and resources.
4. Easy Maintenance and Updates
When it comes to keeping your app up-to-date, web apps have a significant advantage. Unlike native apps, which require users to download and install updates manually, web apps update automatically. As a result, users always have immediate access to the latest features and improvements without any extra effort.
Do Web Apps Have Any Disadvantages?
Web applications come with many benefits, from easy accessibility to real-time updates. However, it's only fair to discuss some of the limitations you might encounter when opting for web app development. Here are a few to consider:
1. Limited Offline Functionality
One of the most notable limitations of web apps is their dependency on internet connectivity. If a user lacks a stable internet connection, the web app might not work or offer limited functionality.
2. Performance Limitations
Another aspect where web apps may lag behind is performance. When compared to native apps built specifically for an operating system, web apps can experience slower speeds, particularly when running intricate animations or processing a large amount of data.
3. Reduced Device Functionality
Web apps are generally limited in terms of device functionalities they can leverage. For example, they might be unable to access a device's camera, GPS, or other hardware features as efficiently as a native app.
Web Application Development Frameworks
Understanding the frameworks available for web application development can make your project run more smoothly and efficiently. Frameworks are toolsets that facilitate the development process, providing structured ways to build web applications more quickly than if you were starting from scratch.
Let's look at some popular front-end and back-end development frameworks:
While front-end frameworks focus on the client side and deal mainly with the user interface, it's worth noting that they often only represent the view layer of a web application. Despite this, for simplicity, they are commonly referred to as frameworks.
Svelte comes with the unique tagline "alternatively enhanced web apps." Unlike traditional frameworks, Svelte acts as a compiler, eliminating the need for a virtual DOM and additional frameworks at runtime. This makes it incredibly performant and easy to learn, although it's still gaining traction for large-scale applications.
Backend frameworks focus on server-side logic and often come with features for database interaction, server deployment, and other backend functionalities.
Here are some of the most commonly used backend development frameworks:
Rails self-identifies as a web application framework that includes everything needed to create database-backed web applications according to the Model-View-Controller (MVC) pattern." Rails specializes in metaprogramming and database-oriented web programming. It is especially well-suited for smaller projects. Ruby on Rails is its most popular variant.
Django labels itself as a "high-level Python Web framework that encourages rapid development and clean, pragmatic design." Django might be your go-to framework if your project involves scientific programming or data manipulation.
Laravel is described as "a web application framework with expressive, elegant syntax" and is written in PHP. It follows the model-view-controller architectural pattern and offers a wide range of tools, making it versatile for different types of applications.
How to Build a Web App?
Building a web application involves multiple steps, from planning, technology selection, development, and testing.
Below are the structured steps that take you through the different phases of web application development.
1. Plan Before You Code
Before writing any code, planning is crucial. Create a high-level overview of your project, detailing the technical approach and timeline for launch. Consider starting with a Minimum Viable Product (MVP), a simplified version of your application, to test its concept.
Creating an MVP allows you to test the core functionalities of your product before investing too much time and resources. It helps you gather valuable feedback early on, making it easier to make iterations and improvements.
Product Design Process (PDP)
In addition to planning, you'll need to undertake a Product Design Process. This starts with business analysis, moves on to user research, then ideation and conceptual development, and ends with execution and technical assessment. A structured design process helps ensure the end product meets user expectations and business goals.
2. Select the Right Tech for Web App Development
Choosing the right technology stack is crucial for your project's success. Web application development follows the typical software development life cycle, where a good team and structured process contribute to the project's success.
Key Questions to Ask
- What are your requirements? This could be the volume of expected traffic, user experience needs, and required security features.
- Who are your target users? Understanding your audience will guide your technology choices.
