Web app development: a beginner’s handbook

The web application development process refers to creating interactive tools or online services that users can access through a web browser.

These applications – or apps – deliver dynamic and feature-rich experiences like desktop or mobile apps, but without requiring additional software installation.

In this guide, you will discover the essentials of web app development, learn about the necessary tools, and receive practical advice on how to embark on this journey – even if you don’t know how to code. Let’s get started.

What is web app development?

Web application development is the practice of building software that is accessible via a web browser.

Unlike traditional websites, which mainly display static information, web apps provide dynamic, interactive functionality. They can look and feel like native applications but only require a stable internet connection and a compatible browser to run.

Types of web applications

• Static web apps: Deliver the same content to every user and typically offer minimal interaction (e.g., a portfolio or a business landing page).
• Dynamic web apps: Generate personalized content in real time based on user interactions (e.g., Facebook or Amazon).
• Single-page applications (SPAs): Load all content on a single web page, updating specific sections as needed (e.g., Gmail or Trello).

Beyond these three categories, you might also encounter other labels, such as progressive web apps (PWAs) and multi-page applications (MPAs). However, these can be considered subtypes or specializations of the broader categories.

Key components of web app development

The process of building web applications is divided into two technological tiers: front-end and back-end development.

Front-end development

Front-end development focuses on the parts of a web app that users see and interact with. This includes:

• HTML: Defines the structure of web content.
• CSS: Controls the appearance, such as layout, color schemes, and typography.
• JavaScript: Manages interactive behaviors and dynamic updates.
• UI/UX: Optimizes design and user interaction to ensure a seamless experience.

Back-end development

Back-end development powers everything behind the scenes. This includes:

• Server-side logic: Processes requests, runs core functions, and communicates with databases.
• Databases: Store and manage data. Popular choices include MySQL, PostgreSQL, and MongoDB.
• APIs (Application Programming Interfaces): Facilitate data exchange between different services or components.

Tools for developing web apps

A professional web app developer typically employs several essential tools.

Code editors
Popular options include Visual Studio Code, Sublime Text, and Atom. These help you write, organize, and navigate your code efficiently.

Version control
Platforms such as GitHub or GitLab help teams collaborate by tracking changes, merging updates, and reverting to previous versions when necessary.

Browser developer tools
Built into browsers like Chrome or Firefox, these tools help with debugging, performance checks, and testing layout changes in real time.

Testing tools and frameworks
Jest, Mocha, Cypress, or Selenium can automate web app testing to ensure your app behaves as expected.

Deployment platforms
Services like GitHub Pages, Netlify, or dedicated hosting platforms like Hostinger Horizons make it easy to publish and share your web app.

How to start developing web apps

Begin by exploring online resources, including free or paid coding tutorials, interactive courses, and official documentation for specific frameworks or libraries.

Popular sites like freeCodeCamp or Codecademy offer structured learning paths that teach foundational skills in an accessible manner. Online communities like Stack Overflow also provide valuable support for beginners.

Once you have a basic understanding of core technologies, it’s time to set up a development environment by installing a preferred code editor and a version control system.

Depending on your goals, you may wish to configure a local server environment on your own computer, either by using Node.js or a full LAMP/LEMP stack, to mirror the architecture of live production systems.

Building a simple web application

Creating a straightforward web application can be an effective way to practice new skills. Here’s how you can build one in five steps.

1. Determine key features

Define the project’s scope and determine the required features by identifying the core problem your app aims to solve. For your first project, start small – aim to create something like a simple to-do list or a notes manager.

2. Sketch wireframes and mockups

You can then detail how each screen or section should look, while considering fundamental UI/UX principles to ensure clarity and ease of use.

Outline a proposed framework for the app to understand user flow and transitions from the moment a visitor arrives until they complete each given task.

3. Choose a technology stack

Choosing the right technology stack is important because it directly affects the app’s performance, scalability, development speed, and maintenance.

Each component plays a specific role in how efficiently the application can be built and expanded, as well as how it’ll function once it’s complete.

Here are some suggestions:

• Front-end: HTML, CSS, and JavaScript frameworks like React or Vue.
• Back-end: Node.js (JavaScript), Python (Django or Flask), Ruby on Rails, or PHP (Laravel).
• Database: MySQL, PostgreSQL, MongoDB.

4. Coding and testing

Writing and testing the code should be a repetitive exercise. Implement the front-end and back-end components, then use testing tools to verify that everything runs smoothly.

This phase ensures that your app’s functionality matches your initial wireframes and is free from performance or logic issues.

5. Deployment

Publish (deploy) your application on a hosting platform or server. Follow your hosting provider’s guidelines on uploading source files, managing environment variables, and connecting a custom domain if necessary.

The future of developing web apps

Until recently, the traditional web application development process hasn’t changed much, aside from new languages and frameworks emerging to suit specific purposes. Its future lies in AI-driven tools and no-code solutions that make app creation faster and more accessible to everyone.
