Lit Components

Lit is a minimal JavaScript library for building reusable web components. Components are created with template literals (backticks), reactive properties (auto-rerender on change), and styles (scoped CSS). Lit components are Web Components: they work in any HTML page, any framework, or standalone. A Lit component is ~5KB; the entire framework is ~15KB. Unlike React, Lit doesn't require a build step or JSX transpiler. Write HTML as strings, add reactivity, deploy. As frontend architectures fragment (React, Vue, Angular, Svelte), building components that work everywhere is valuable. Web Components + Lit enable true portability: build once, use in any framework. Companies building design systems and component libraries use Lit to reach the widest audience. Bundle sizes are tiny (Lit ~15KB vs React 40KB+), so sites load faster. Learning Lit teaches you Web Components standards, which is evergreen knowledge.
