What is frontend and what is backend?
How often do you hear the words "backend" and "frontend"? I think nowadays these words are very popular. But, do you really understand what they mean exactly? If you still not sure, let's talk about that here, in our new article.
Let's start with definitions of these terms.
In software engineering, the terms front end and back end refer to the separation of concerns between the presentation layer (front end), and the data access layer (back end) of a piece of software, or the physical infrastructure or hardware. In the client-server model, the client is usually considered the front end and the server is usually considered the back end, even when some presentation work is actually done on the server itself. (by Wikipedia)
While these definitions do make a lot of sense, I think we can agree that it is still not drawing us a full picture of this frontend/backend situation. For this reason, let us try to explain it in simple words. We will talk about it from regular users' of websites perspective instead of using fancy tech terms.
When you open a website, all that you can see on the screen is basically a frontend. Pictures, text, buttons, etc. - all of it is the frontend. As a user, you always connect with that part of the website.
Frontend is all that a browser can read, display and/or run.
HTML(HyperText Markup Language) "tells" the browser what to show. It is letting our browser know what to display for us: title, paragraph, some lists or elements of a list.
CSS tells the browser how to show it. For example, how many pixels should one side of the page be away from the first title or paragraph and what color of that text should be displayed.
Backend is another side of the website. You can’t see what is going on and for the biggest part of users it is a mystery. The logic of the website is implemented on the backend.
For example, you are asking Google for some information and when you click “Enter”, the frontend is over and the backend starts to work. Your request is sent to the server where the search algorithms are. This is where all the “magic” happens. As soon as the information that you were looking for appeared on the screen, it again returns into the frontend zone.
A server is the same thing as a computer, only more powerful. It stores data and responds to user requests.
And now, when we more or less understand the differences between frontend and backend, let's talk about the technical part of that topic. If you have a business and you need a website, like most modern businesses, you should definitely know what tools the developers use. Right now, we have a lot of different frameworks for building websites, sometimes even developers don’t remember all of them. Different technologies are used for the implementation of different functions of websites. It’s like you can’t build a house using only one hummer. You need a lot of tools! The same situation happens with the website. The development of the website is just like building a house and developers , just like builders, have a lot of tools for building. Depending on the functions of your future website, you need frameworks that can solve these tasks. Now we will tell you about the most popular frameworks for frontend and backend available today.
Another very popular framework for web development in IT companies as Google, Youtube and Instagram but in Python language. Django has Model-View-Template architecture (or MVT) and follows the best design principles. You may no longer worry about many complex and important things. Particular priority is given to security. The framework implements many important principles of protection on its own.
Popular Ruby framework with Model-View-Controller (or MVC) architecture. Favorite framework in such companies as Airbnb, GitHub and Twitter. Ruby on Rails can save you time for building a website because developers will use less code, but functionality will be the same. This framework will solve almost any problem for your project, but in less time.
It’s also a framework with Model-View-Controller (or MVC) architecture, but for PHP- the most popular language in web development. Many features, such as API support, are available already in the framework. In addition, there are many useful packages with additional functionality.
Our list of backend frameworks will be incomplete without Java. So, let me introduce the Spring framework. It’s a professional, rather flexible and very reliable tool for development. Spring represents several frameworks in one and most of it can work independently.
This framework also originates from Google and becomes one of the biggest JS frameworks very fast. It’s a flexible tool with a progressive structure. And it is easy to integrate even in an already existing project, if you need it. The big ecosystem allows the development of difficult applications but in less time.
Some of these frameworks are more popular, some of them less. But all of them are the best in the niche and you can build big or small projects with these tools. Everything depends on you and your wishes. So now, if somebody asks you which one of the frameworks you prefer to use for the development of your business, you will know where to find the answer.
