Building reusable UI components with Lit
A practical approach to component APIs, Shadow DOM styling, and keeping custom elements simple enough to maintain.
Reusable components work best when their public API is small, predictable, and shaped around the real jobs the interface needs to support.
Lit gives you a focused base for custom elements without turning every component into a framework-specific island. You still get reactive properties, scoped templates, and a pleasant rendering model.
For most production components, I start with the attributes and events first. Once the outside contract feels clear, the internal template and styles become easier to reason about.
Shadow DOM is useful for encapsulation, but design tokens and CSS custom properties keep the component flexible enough to fit inside a real product system.
