TwigComponent

Reusable UI components with PHP classes + Twig templates. Think React/Vue components, but server-rendered with zero JavaScript.

Two flavors exist: class components (PHP class + Twig template) for components that need logic, services, or computed properties, and anonymous components (Twig-only, no PHP class) for simple presentational elements.

When to Use TwigComponent

Use TwigComponent when you need reusable markup with props but no server re-rendering after the initial render. If the component needs to react to user input (re-render via AJAX, data binding, actions), use LiveComponent instead.

Good candidates: buttons, alerts, cards, badges, icons, form widgets, layout sections, navigation items, table rows, modals (structure only).
