What is required to develop a website?

Web de­vel­op­ers can integrate dynamic content into their projects using a variety of tools, tailoring the ex­pe­ri­ence to in­di­vid­ual users. A key re­quire­ment for this is pro­fes­sion­al web hosting that provides the necessary resources to support modern web de­vel­op­ment.

The technical foun­da­tions of a website

The foun­da­tion of any online presence is a suitable server. Es­tab­lished web hosting providers typically offer complete packages that include not only the necessary storage space, but also server resources like RAM, a custom domain, databases, and essential web de­vel­op­ment tools. It is also possible to choose to provide the technical foun­da­tions yourself.

Domain

Every project on the World Wide Web is accessed through a unique, iden­ti­fi­able name. This domain is one of the core com­po­nents of a website. Domains follow the hi­er­ar­chi­cal structure of the Domain Name System and consist of a top-level domain (like .com or .org), a freely chosen domain name (the second-level domain), and optional sub­do­mains. Domain reg­is­tra­tion is handled by a web service provider, who submits the request to the ap­pro­pri­ate registry. When choosing a domain, it’s best to go with short, clear names and widely rec­og­nized top-level domains.

Web space

Every website consists of data that must be stored on a web server to be ac­ces­si­ble via the internet. That’s why web hosting plans always include a certain amount of storage space for HTML documents, stylesheets, images, videos, databases, and all other website files. Uploading this data is typically done via the File Transfer Protocol (FTP) or the encrypted SFTP (SSH File Transfer Protocol) using an ap­pro­pri­ate FTP program like FileZilla or WinSCP. For your web project to remain scalable, it’s essential that your web space can be expanded at any time as needed.

Database

Modern websites often use databases to deliver content dy­nam­i­cal­ly and manage user data. Instead of serving static HTML pages stored on the server, database-driven projects generate web pages on the fly with each request. Depending on the use case, web de­vel­op­ers rely on either re­la­tion­al databases (SQL) or NoSQL databases.

Re­la­tion­al databases like MySQL, MariaDB, or Post­greSQL store in­for­ma­tion in tables and link them using unique keys (IDs). This structure is ideal for ap­pli­ca­tions that require clearly defined re­la­tion­ships between data, such as user accounts, orders, or product catalogs. NoSQL databases like MongoDB, Firebase, or Redis support dynamic schema changes, making them es­pe­cial­ly useful for scalable or high-per­for­mance web apps and real-time ap­pli­ca­tions.

Web server

Depending on the hosting model, the server can be shared (shared hosting or dedicated (with your own hardware, a VPS, or cloud in­fra­struc­ture). Large web projects often use ad­di­tion­al tech­nolo­gies such as load balancing and Content Delivery Networks (CDNs) to improve per­for­mance. Modern ap­pli­ca­tions also rely on container tech­nolo­gies like Docker and Ku­ber­netes to deploy server ap­pli­ca­tions in a flexible and scalable way.

The term “web server” refers to the core software component re­spon­si­ble for de­liv­er­ing websites and web ap­pli­ca­tions. Web servers handle requests from browsers via the HTTP(S) protocol and return the ap­pro­pri­ate content. Some of the most popular solutions include Apache, NGINX, and LiteSpeed.

The most important tools for de­vel­op­ing a website

Once the foun­da­tion of your web project is in place, you have several options for de­vel­op­ing your own website. These range from user-friendly website builders with limited design flex­i­bil­i­ty to more advanced content man­age­ment systems (CMS) and fully custom-coded solutions. Website builders, based on the WYSIWYG principle (“What You See Is What You Get”), are primarily aimed at beginners with no pro­gram­ming knowledge. Running a CMS, on the other hand, requires some technical ex­pe­ri­ence. De­vel­op­ers who want full control often choose to build their project from scratch in a code editor—usually with the help of a framework. This approach requires a solid un­der­stand­ing of basic pro­gram­ming languages such as HTML, CSS, JavaScript, and PHP. However, practical tools like prebuilt code templates and AI-assisted pro­gram­ming now make the process sig­nif­i­cant­ly easier.

HTML

HTML (hypertext markup language) plays an important role in web de­vel­op­ment by se­man­ti­cal­ly struc­tur­ing digital content; a process that’s carried out by using what de­vel­op­ers refer to as tags. This approach allows you to define elements such as text blocks, headings, graphics, or hy­per­links. The resulting markup forms the basic structure of any webpage. A simple static website is es­sen­tial­ly just a col­lec­tion of in­ter­linked HTML documents. The current standard, HTML5, also adds markup support for audio and video elements.

CSS

The visual pre­sen­ta­tion of content is defined using CSS, the standard for­mat­ting language for HTML documents. Web de­vel­op­ers use CSS to assign display rules to the elements defined in the HTML code. The current standard, CSS3, includes not only layout, color, and ty­pog­ra­phy rules but also features like an­i­ma­tions, gradients, and shadows.

JavaScript/Type­script

Visitors interact with modern websites by using input fields, drop-down menus, or slide shows. JavaScript or its extension, Type­Script, come into play whenever dynamic content like this is to be used on an HTML site. The script languages expand the HTML and CSS framework by eval­u­at­ing user in­ter­ac­tions and reloading, updating, or changing page content.

PHP

While static websites are ready to be accessed on web servers, dynamic websites are first generated when a request is made through a web browser. This process is made possible with the script language PHP. PHP programs are in­ter­pret­ed server-side. Instead of de­liv­er­ing the source code of dynamic websites directly onto the browser, the web server transfers the file to a PHP in­ter­preter. This in­ter­preter then generates the requested website–often by using in­for­ma­tion deposited in the database–and returns it to the web server. From there, the in­ter­preter readout is sent to the browser. Ad­di­tion­al script languages used for de­vel­op­ing dynamic websites are Perl and Python.

Frame­works

Modern web de­vel­op­ment in­creas­ing­ly relies on frame­works to speed up de­vel­op­ment and provide proven struc­tures. Frontend frame­works like Angular and React simplify the creation of dynamic, in­ter­ac­tive user in­ter­faces. They support a component-based ar­chi­tec­ture and improve per­for­mance using virtual DOMs.

Backend frame­works like Flask and Django support server-side de­vel­op­ment by providing features such as routing, database in­te­gra­tion, API man­age­ment, and security functions. By combining frontend and backend frame­works, de­vel­op­ers can build scalable web ap­pli­ca­tions while op­ti­miz­ing de­vel­op­ment time.

APIs

APIs (Ap­pli­ca­tion Pro­gram­ming In­ter­faces) are in­ter­faces that allow web projects to com­mu­ni­cate with other ap­pli­ca­tions. This enables a website to, for example, fetch data from a server or integrate third-party services such as payment providers or map services. There are various types of APIs, including REST and GraphQL, which deliver data in a defined format. Many modern web ap­pli­ca­tions rely on APIs for dynamic content or to add extra func­tion­al­i­ty.

Re­spon­sive web design and per­for­mance op­ti­miza­tion

Modern websites must adapt seam­less­ly to different screen sizes. Re­spon­sive web design ensures that content is displayed optimally on smart­phones, tablets, and desktops. This is achieved through flexible layouts, CSS media queries, and mobile-first design strate­gies. Depending on the project, it may also be worth con­sid­er­ing whether tra­di­tion­al re­spon­sive design, a dedicated mobile site, or a mobile app is the best fit.

In addition to visual display, load time is also critical. Per­for­mance op­ti­miza­tion is one of the most important aspects of modern web de­vel­op­ment. It includes tech­niques such as:

• Com­press­ing images
• Caching
• Com­press­ing CSS
• Min­i­miz­ing JavaScript/Type­Script
• Lazy loading

Security measures and testing

Security is a key factor in the success of any web project and should be con­sid­ered early in the de­vel­op­ment process. Websites should be protected with SSL/TLS en­cryp­tion, strong passwords, and safe­guards against attacks such as XSS or SQL in­jec­tions. Regular updates and backups are also essential.

Es­pe­cial­ly when de­vel­op­ing more complex web projects from scratch, testing is a crucial part of quality assurance. There are various testing tools available for web de­vel­op­ment. If you only want to test specific parts of the web project, you can use unit tests. There are different test frame­works for this purpose, such as PHPUnit for PHP or JSUnit for JavaScript.
