Two Faces of Web Development

A website or app is like an iceberg. The part that the user sees (Frontend) and the huge structure under the water (Backend) work together to create the digital experience.

What is Frontend?

Frontend is also known as "Client-side". When you enter a website, everything you see, click, and interact with is the work of the Frontend developer. It is the version of the design put into code.

Core Technologies:

HTML5: The skeleton and content of the page.
CSS3/Tailwind: Visual design, colors, layout.
JavaScript (ES6+): Dynamics, animations and logic.
Frameworkler: React, Vue.js, Angular, Svelte.

Just code is not enough for a professional Frontend; UI/UX (User Interface/Experience) knowledge is also required. As Eka Sunucu Web Design We use the most modern Frontend technologies in our services.

What is Backend?

Backend is called "Server-side". It is the brain of the site. Database operations, user authentication, server configuration and business logic work here. The user does not see it, but it makes the system work.

Core Technologies:

Languages: PHP, Python, Java, Node.js, Go.
Databases: MySQL, PostgreSQL, MongoDB.
Servers: Apache, Nginx, Litespeed.
API: RESTful, GraphQL.

A powerful backend requires a powerful server. For your PHP and MySQL based projects Linux HostingYou should prefer Windows servers for your .NET projects.

Examples from the Code World

Let's see how the same process (Data Extraction) looks like on the Frontend and Backend side.

frontend_app.js (JavaScript)

                    //Runs in user browser

                    asynchronous function getUserData() {

                      try {

                        const response = await fetch('/api/users/1');

                        const data = await response.json();

                        document.getElementById('username').innerText = data.name;

                      } catch (error) {

                        console.error('Error:', error);

                      }

                    }

backend_api.php (PHP)

                    // Runs on the server side (Backend)

                    $user_id = $_GET['id'];

                    // Secure data extraction from database

                    $stmt = $pdo->prepare("SELECT name, email FROM users WHERE id = ?");

                    $stmt->execute([$user_id]);

                    $user = $stmt->fetch(PDO::FETCH_ASSOC);

                    header('Content-Type: application/json');

                    echo json_encode($user);
