Web development is based on two main pillars: front-end and back-end. These two areas each have their own specificities, but interact with each other to build high-performance, attractive, reliable and secure applications.
Front-end: the user experience
The front end is the visible part of a website or application. It includes everything the user sees and interacts with: interface, navigation, forms, animations, design, etc.
A front-end developer generally uses HTML, CSS and JavaScript to create websites, but there are also many commonly used frameworks, such as Angular and React, which can improve the creation process.
A high-quality front end is essential to ensure that users have the best possible experience when visiting a website. It is therefore essential to pay attention to several points: the interface must be functional, clear and adaptable to all types of screens (computers, tablets, phones). It must also be accessible, i.e. designed so that as many people as possible can use it, including people with disabilities. Every part of the interface must be designed to make the experience as enjoyable as possible.
The back end: data management
The back-end is the invisible part of an application. It manages data, authentication, security and interactions with databases.
The purpose of a back-end is to create access points so that applications, such as a website or mobile app, can access or manage data easily and in a standardised way without having to worry about or know how and where that data is stored.
A high-quality back end is essential to ensure not only good data management, but also data security. It is important that no one can access, modify or delete data that does not belong to them. It must also be practical and easy to use in order to simplify the development of the applications that will use it.
The essential balance between back-end and front-end
A good project has both a high-quality front end and back end. Having a practical and user-friendly interface is one thing, but if the data takes several seconds to display because the back end is not optimised, then the user is likely to become impatient. Conversely, if the back end works perfectly, is fast, practical and secure, but the interface is unclear, users may not only fail to understand what they need to do, but they will certainly not want to return to the site.
In conclusion
Although very different, the front-end and back-end must be designed together. A beautiful, practical and intuitive interface, linked to fast and secure data management, allows you to create user-oriented applications, while taking into account the ease of development and maintenance.
