A Practical Guide to Frontend System Design
This book focuses on a part of frontend development that is often overlooked: system design. Instead of treating the frontend as a collection of isolated components, it looks at how data, state, performance, and architecture work together in a real application. All ideas are explained using a single, evolving board application. Each chapter builds on the previous one, so you can see how small decisions accumulate into a larger system.
Juntao Qiu
I’m a frontend engineer and educator with over a decade of experience building and maintaining large-scale frontend applications. Over the years, I’ve worked on complex systems where performance, data modeling, and long-term maintainability mattered more than quick wins. This book is a reflection of those experiences — focusing on the design decisions that make frontend systems easier to evolve over time. I write and teach to help developers move beyond ad-hoc solutions and develop a clearer, more systematic way of thinking about frontend architecture.
