About

👋 Hi, I’m Juntao — a software developer, author, and content creator who helps developers write cleaner, more maintainable frontend code. On this channel, I share practical coding walkthroughs, real-world refactoring sessions, and system design insights — all focused on React, frontend architecture, and clean code practices. With over a decade of experience in both frontend and backend development, I’m especially passionate about Test-Driven Development (TDD) and helping engineers grow from just making things work to making them robust and scalable. I’ve authored several books, including: - React Anti-Patterns (2024) - Test-Driven Development with React and TypeScript (2023) - React Clean Code (2022) - 3 Web Designs in 3 Weeks (2022) If you're a frontend engineer who cares about writing better code — you're in the right place.

Video Description

In this walk-through, we tackle a common issue with reusable UI components: an overgrown template selector that’s become difficult to manage, maintain, and customize. Originally built to be generic, this component has evolved into a complex structure weighed down by customizations. Watch as I refactor it using the headless component pattern with React Context. By moving all logic into a central, UI-free context and breaking out visual elements—like Tiles, Categories, and Search Bars—into reusable atomic components, we unlock a flexible solution that’s easy to adapt. Whether building from scratch or using the default setup, this approach brings simplicity, power, and ultimate composability to your React code.
