Front-end, back-end, and full-stack: What’s the difference?

Digital Tools

Front-end, back-end, and full-stack are widely used terms in the world of web development. Knowing the meaning of each one will help you identify the type of programmer that is needed for different projects.

The development of websites requires the participation of professionals in programming systems and applications for the Internet. These specialists combine series of back-end (server-side) and front-end (client-side) processes, so that users can access a particular information through a browser and even perform data exchange.

On the other hand, the evolution of technology and the increasing demands of users have led websites to go from being static or just informative, to be dynamic and interactive. This is where a fine line begins to be drawn between what is web design and development, which finally defines the functions and skills of different types of programmers. Let’s look at this in detail:

Front-end programming

The front-end refers to the part of the software that is facing the user. It can also be seen as the interface of the application or everything that is visible from the browser. That is why it is said to run on the client side and correspond to the UI (User Interface) layer or presentation layer.

In this context, the front-end developer is responsible for recreating the site design and adding functionalities. The latter has to do with the logic of the presentation and the interaction of the user with the application, based on events. The programming languages ​​used in this case are: HTML, CSS and JavaScript.

Sometimes, for the front-end development phase, work teams are formed that include profiles such as: UX (User Experience) designer, layout designer and graphic designer. On the contrary, there are other scenarios in which the same programmer plays all those roles.

Back-end programming

Back-end development is directly related to creating the software architecture. It is that part that runs on a physical server or in the cloud, which is invisible for the website users. It is here where the information is processed and stored from the data obtained through the application interface made by the front-end.

In order to do his job, a back-end programmer must handle complex languages ​​such as PHP, Java, Python or C #, among others. In addition, the knowledge covers database managers, APIs (Application Programming Interface), libraries, frameworks, interconnectivity, as well as other tools that complement his profile.

Full-stack programming

When we talk about the term full-stack, it is often associated with the “whole” project. It is the set of front-end and back-end, involving all stages of site development, from planning to production.

Therefore, a full-stack programmer is able to face the challenges that arise from both sides (client and server). These experts are usually hired to implement sites for small enterprises, on their own. As well as to supervise the complete process of large-scale technological solutions, due to their ability to understand the details of the front-end, the back-end and their integration.

Lastly, each development cycle and type of programmer has its importance in an online world where the need to create attractive and functional designs that capture the audience intensifies every day. And of course, you cannot leave behind the interaction and data processing that allows you to connect with prospects and customers to facilitate the achievement of the objectives of business owners or managers.

And you, what do you think of all this? Do you now understand the difference between these concepts?
