Framework-Specific Component Implementation

While design tokens, visual scales, interaction state matrices and accessibility contracts can be shared across a product ecosystem, component implementations must follow the idiomatic reactivity, slot/projection, typing and lifecycle patterns of the project's actual frontend framework. Never force a React-style API onto Vue or Angular, or assume a component works across frameworks without verification.

1. Separate Shared Visual Foundations From Framework Bindings

• Framework-agnostic layer: design tokens (CSS Custom Properties --*), typography/spacing scales, SVG icon assets, semantic CSS classes and state/accessibility specifications.
• Framework-idiomatic layer: component state, event emission, content projection/slots, template refs, form-control integration and portal/teleport mounting.
• Coordinate complex framework-specific patterns with the team's corresponding frontend framework specialist.

2. Idiomatic Patterns by Stack

React (React 18 / 19+)

• Forward refs (ref prop in React 19 or forwardRef in React 18) and spread remaining native HTML props (...rest typed via ComponentPropsWithoutRef<'button'>) onto the underlying element.
• Use useId() for deterministic SSR-safe ARIA/label IDs and createPortal for modals/popovers when needed.
• Support both controlled (value + onChange) and uncontrolled (defaultValue) usage cleanly, and compose multi-part widgets with React Context (Dialog.Root, Dialog.Trigger, Dialog.Content).

Vue 3 (<script setup lang="ts">)

• Use typed defineProps<...>(), defineEmits<...>() and defineModel<...>() (for v-model two-way binding) rather than React-style onChange props.
• Use named <slot name="header" :open="isOpen"> and scoped slots (defineSlots<...>()), useId() (Vue 3.5+) for accessible IDs, provide/inject with InjectionKey<T> for compound components, and <Teleport to="body"> for overlays.
• Understand inheritAttrs (defineOptions({ inheritAttrs: false }) + v-bind="$attrs" on the inner <input> or <button> when wrapping a field in a container <div>).

Angular (Standalone Components, Signals, Reactive Forms)

• Build standalone components with ChangeDetectionStrategy.OnPush, typed inputs (input() / @Input()) and outputs (output() / @Output()).
• Prefer attribute/component selectors (button[appButton]) on native <button> and <a> elements so consumers retain full access to native attributes (disabled, type, aria-*) without wrapper-div indirection!
• Use <ng-content select="..."> or ng-template for slots, Angular CDK (@angular/cdk/a11y, Overlay, Portal) where present, and implement ControlValueAccessor (or Signal forms integration) for custom form controls.

Native Web / Vanilla TypeScript & Web Components

• Build on semantic HTML (<dialog>, <details>, <button>, <form>), progressive enhancement, scoped data attributes (data-variant="primary", data-state="open"), and clean event listener teardown (AbortController signals).
