Web Development Essentials Study Companion: Getting Ready for the LPI 030-100 Exam

Web Development Essentials Study Companion is designed to equip aspiring web developers with a comprehensive understanding of both client-side and server-side technologies as you study for the Linux Professional Institute's 030-100 exam. The book begins by laying a solid foundation in software development concepts, introducing the components of a web application, and explaining how the HTTP protocol and RESTful architecture work together to enable modern web communication. These early chapters are essential for grasping how web applications function as a whole. We then move into a detailed exploration of front-end development, covering the foundational topics of HTML for structuring content, CSS for styling, and JavaScript for creating interactivity. Readers will learn how to use various HTML tags, including semantics and forms, style content using CSS selectors and the box model and manipulate the Document Object Model (DOM) with JavaScript. These chapters emphasize the practical skills necessary to build dynamic, user-friendly interfaces. In the final section, readers are introduced to server-side development using NodeJS. They’ll explore the Express framework for building robust back-end applications and learn how to connect these applications to a SQLite database. By the end of the book, not only will you have the knowledge and confidence to sit the LPI 030-100 exam but the real-world skills needed to start building full-stack web applications from the ground up. You Will Learn to: Understand the core architecture of web applications, including software development principles, HTTP protocol, and RESTful APIs.
