Frontend Architecture with Feature-Sliced Design (FSD)

As frontend applications grow, maintaining a clean and scalable codebase becomes a major challenge. Understanding how to organize your code logically prevents technical debt and keeps development fast and predictable. This course guides you through the foundational principles of modern frontend architecture, focusing on Feature-Sliced Design (FSD). You will learn how to apply these structural concepts to popular frameworks like React, Vue, Next.js, Nuxt, Angular, and Svelte, ensuring your projects remain maintainable as they scale. In this course, you will: 1. Understand the core terminology and layers of Feature-Sliced Design (FSD); 2. Analyze how to decompose complex applications into scalable modules and features; 3. Apply FSD principles across different frameworks including React, Vue, and Next.js; 4. Configure clean boundaries and dependency rules between application layers; 5. Practice refactoring messy codebases into structured, predictable architectures; 6. Learn modern state management integration and performance best practices within FSD. The course starts with essential architectural definitions and core concepts before moving step-by-step through practical written scenarios. You will read conceptual breakdowns and analyze structured code examples to see how FSD operates in real-world multi-framework environments. This text-only course is designed for frontend developers who want to master application structure; no prior architectural experience is required, though basic familiarity with any modern JavaScript framework is helpful.
