Stefan Grevelink
Web development is the process of building and maintaining websites and web applications. It includes everything that ensures a website functions properly, from structure and logic to user interaction. Although it is often confused with web design, there is a clear difference: web design focuses on the visual and user-friendly aspects of a website, while web development is about the technical implementation of those designs.
Frontend vs. backend development: what’s the difference?
In web development, we distinguish between frontend and backend development:
- Frontend development focuses on the part of the website that users see and interact with. Think of buttons, fonts, animations, and layout. Frontend developers use technologies such as HTML, CSS, and JavaScript to build these elements.
- Backend development is all about the server, database, and behind-the-scenes logic. Backend developers ensure that the frontend receives data, users are authenticated, and information is stored correctly. Popular backend technologies include PHP, Laravel, Node.js, and Python.
Important programming languages and frameworks explained
Web development makes use of various programming languages and frameworks:
-
HTML (HyperText Markup Language): the basic structure of every web page.
-
CSS (Cascading Style Sheets): defines the styling and visual appearance of websites.
-
JavaScript: makes web pages interactive, from dropdown menus to live search results.
-
React: a JavaScript framework for building fast and dynamic user interfaces.
-
Laravel: a PHP framework commonly used to develop powerful backend systems.
From concept to launch: the phases of web development
Developing a website involves several key phases:
-
Planning & strategy: analyzing needs, setting goals, and creating wireframes.
-
Design: developing the visual concept based on the brand identity.
-
Development: technically building the website (both frontend and backend).
-
Testing: identifying bugs, testing usability, and optimizing performance.
-
Launch: the website goes live and becomes accessible to visitors.
-
Maintenance & Optimization: ongoing updates, security checks, and performance improvements.
