Web Development

This is the process of creating, building and maintaining web applications and websites ensuring they are functional, responsive, and user friendly. It is divided into front-end development and backend development

FRONTEND DEVELOPMENT Deals with the visual aspects of a website. The aspects are layouts, buttons, images and interactive elements.

TECHNOLOGIES USED HTML - defines the structures of a webpage CSS – The styling and appearance Javascript – deals with the interactivity and functionality Modern frontend development involves frameworks like React, Angular or Vue.js which help streamline the development and create dynamic user experiences. Imagine you’re browsing an online store.

The frontend includes:

• Layout and Design: The arrangement of images, text, and buttons using HTML and CSS.

• Interactivity: Dynamic elements like image sliders, forms, and menus, often built with JavaScript or frameworks like React or Angular.

• Responsiveness: The design adapts to different screen sizes—from desktops to mobile devices—ensuring usability regardless of the device.

For instance, when you click on a product image, JavaScript might trigger a zoom-in effect or open a modal window, enhancing your shopping experience.

BACKEND DEVELOPMENT

Responsible for the server-side logic, database management and application performance It ensures that the front end retrieves and displays necessary data while handling requests securely. Fullstack Development This involves a combination of front-end and back-end development, allowing a developer to handle a complete web development process.

UNDERSTANDING BACKEND DEVELOPMENT

Backend development is the backbone of web applications responsible for processing requests, managing data, and ensuring smooth communication between the user interface and the database. This involves working with server-side languages, databases, and APIs to handle user requests and deliver correct responses.

COMPONENTS OF BACKEND DEVELOPMENT

Server which is a computer that processes requests and sends responses to users. The backend runs on a server. The most commonly used server technologies include Apache, Nginx and Microsoft IIS The database stores information such as user data, content, and transactions the backend system interacts with the database to store and retrieve data. The Application logic on the other side is the core functionality that processes user requests and business logic.

BACKEND PROGRAMMING LANGUAGES AND FRAMEWORKS

Python -Django, Flask

PHP- Laravel, CodeIgniter

Javascript – Node.js, Express.js

Ruby – Ruby on Rails

Java- Spring Boot

DATABASES USED IN BACKEND DEVELOPMENT

There are two main types of databases;

Relational Databases which are SQL-based databases and include MySQL, PostgreSQL, and Microsoft SQL Server

Non-relational/No SQL Databases include MongoDB, Firebase, and Cassandra NoSQL databases are often used for flexible, scalable applications Continuing with our online store, when you perform a search:

1. Request Handling: Your query is sent from the frontend to the backend.

2. Processing: The backend searches the database for matching products.

3. Response Generation: The results are sent back to the frontend in a format (often JSON) that the browser can display.

HOW FRONTEND AND BACKEND WORK TOGETHER

The interaction between frontend and backend is critical:

1. User Request: A user interacts with the frontend (e.g., clicks a button).

2. Data Processing: The frontend sends a request to the backend.

3. Response: The backend processes the request, interacts with the database, and sends data back.

4. Display: The frontend takes this data and updates the UI accordingly.

APIS (APPLICATION PROGRAMMING INTERFACES)

They allow communication between the front end and the back end. APIs enable data exchange between systems using protocols like REST and GraphQL. Backend Developers build APIs to expose services and data for frontend applications or third-party integrations
