Lit Web Components

A guide to building fast, lightweight, standards-based web components using Lit's reactive properties and declarative templates.

Usage

Ask about Lit elements, reactive properties, templates, or web component patterns.

Examples

• "Create a reusable button component with Lit"
• "How do I handle events in Lit web components?"
• "Build a form element with reactive validation"

Guidelines

• Use reactive properties for state that triggers re-renders
• Leverage Lit's html tagged template literals for efficient updates
• Use CSS shadow parts for external styling hooks
• Keep components small and composable
• Use events for child-to-parent communication
