Web development is an area that is constantly evolving. New technologies and methods are continuously being developed. However, it’s also important to know some of the basics.
If you want to work in this field, you should definitely master the following points, as they will be indispensable in your daily work:
- Programming languages: If you want to work as a web developer, one skill is absolutely essential. Programming languages are mandatory in this field. You must be proficient in scripting languages such as HTML, CSS and Javascript. You must be able to write semantically correct HTML codes that are well structured. This involves defining colors, fonts, sizes and positioning of elements on the website.
- Libraries and frameworks: Web development is made more efficient and organized by JavaScript frameworks, Angular JS, React and Vue.js. Ready-made codes are used for general tasks so that the web developer can concentrate on projects.
- CSS preprocessors: The capabilities of CSS are enhanced by preprocessors such as Sass and Less. This allows web developers to write cleaner, more organised code that is easier to maintain. Developers can create reusable styles and components that can easily be shared and used across different projects.
- Responsive design: Many more mobile devices are now being used. Therefore, responsive designs must be created that adapt to different screen sizes. A combination of responsive grid systems, media queries and flexible images and media is used. This improves the user experience.
- Web Performance: Naturally, a good user experience also includes a website that loads and responds quickly. That's why a web developer must also be familiar with techniques that optimize web performance.
- Database management: Since most websites use databases to store and retrieve their data, a web developer must also have a good understanding of working with databases. This includes MySQL, MongoDB and PostgreSQL.
- Version management: There are version management systems such as Git that a web developer can use to track changes to the code. They can collaborate with other developers, but also revert to an earlier version if necessary.
- Web Security: The security of websites is one of the highest priorities — it also protects the users themselves. The web developer’s task is to implement measures that safeguard websites and to identify potential vulnerabilities. They must protect against common attacks such as SQL injection, cross-site scripting (XSS), and cross-site request forgery (CSRF).
- Communication and cooperation: Communication is a very important part of a web developer's work. They work with teams, but also with designers and project managers. It is therefore important that he communicates clearly and also works well with the respective parties involved.
- Lifelong learning: This is a readiness that every web developer needs. New web dev technologies and processes are constantly being developed and they need to keep up with the times. That's why they need to keep learning in the areas we've mentioned in the other 9 points and also learn new skills. It's a job where the learning never stops.
