RAC 1.22.1 Component Expansion Roadmap

Strategic roadmap and architectural blueprints for elevating React Aria Components into enterprise-grade Hashti primitives.

RAC 1.22.1 Component Expansion Roadmap

Hashti combines disciplined enterprise geometry, React Aria Components’ (RAC 1.22.1) battle-tested W3C WAI-ARIA behavioral foundation, and Frame’s brand aesthetic.

Currently, Hashti exports 45 polished component families. However, [email protected] offers powerful low-level capabilities that are either raw re-exports, trapped inside monolithic wrappers, or unexposed. This roadmap outlines Hashti’s phased architecture plan to systematically elevate these primitives into first-class, theme-aware, accessible building blocks.

Architectural Principles (HeroUI v3 Elevation Model)

Following the design craft established in HeroUI v3 and modern React 19 standards, Hashti elevates every RAC primitive using six structural guarantees:

  1. React 19 Ref-as-Prop & Compound Namespacing: No boilerplate forwardRef. Components export ergonomic namespaces (e.g. Toolbar.Root, Toolbar.Group, Toolbar.Item) using Object.assign.
  2. Contextual Compound Slot Distribution: Container states (size, variant, isDisabled, orientation) propagate downwards through typed React Contexts without prop drilling.
  3. Defensive Exit Animation Lifecycle (useOverlayExitHold): WebKit and Safari layout-effect race conditions are guarded using active animation probes and flushSync unmounting to eliminate 1-frame opacity flashes.
  4. Collection Slot Injection (createCollectionSlot): Preserves RAC’s CollectionBuilder AST while cleanly supporting sticky headers, empty states, and custom decorative scrollbars.
  5. Accessible Clearable Actions: Clear triggers avoid nested <button> anti-patterns, rendering presentation spans with pointer event isolation and keyboard interceptors (Backspace/Delete).
  6. Multi-Theme Token Fidelity: Direct CSS variable bindings across all 8 themes (white, g10, g90, g100, relay-light, relay-dark, frame-light, frame-dark) and 3 layer depths.

Phase 3: Immediate High-Impact Controls (Foundation & Utilities)

Phase 3 targets fundamental layout and workflow primitives required across enterprise dashboards and editors.

        M["Meter<br/>(Semantic thresholds: low, high, optimum)"]
        LB["Standalone ListBox<br/>(Command palettes & dual-column pickers)"]
    end

1. Toolbar Suite (Toolbar)

  • Motivation: Replaces raw RAC re-export with an accessible tool ribbon providing roving tabindex, horizontal/vertical orientations, button group wrappers, and dividers.
  • Subcomponents: Toolbar.Root, Toolbar.Group, Toolbar.Item, Toolbar.Separator.
  • Keyboard Contract: Single tab stop. Arrow keys move between tools; Home and End jump to boundaries.

2. Disclosure & DisclosureGroup (Disclosure)

  • Motivation: Extends the internal logic of Accordion into a standalone, single-panel collapsible control (e.g., for “Advanced Settings” sections in cards and forms).
  • Subcomponents: Disclosure.Root, Disclosure.Trigger, Disclosure.Panel.
  • Features: Hardware-accelerated CSS grid height animations (grid-template-rows: 0fr -> 1fr), custom indicator icons, and lazy content mounting.

3. DropZone & FileTrigger

  • Motivation: Decouples file ingestion from the monolithic FileUploader wrapper. Developers can turn any custom card, canvas, or table row into an accessible drop target.
  • Anatomy: 
    <DropZone onDrop={handleFiles}>
  <FileTrigger acceptedFileTypes={["image/png", "image/svg+xml"]}>
    <Button variant="secondary">Upload Vector Asset</Button>
  </FileTrigger>
  <Text slot="label">or drag and drop files here</Text>
</DropZone>

4. Semantic Meter (Meter)

  • Motivation: Elevates the generic progress bar into a true semantic gauge supporting W3C <meter> semantics with explicit threshold ranges (low, high, optimum).
  • Dynamic Color Tone: Automatically switches tokens from Success (Turquoise/Emerald) to Warning (Amber) or Critical (Terracotta) as values traverse thresholds.

Phase 4: Advanced Data & Productivity Workflows

Phase 4 delivers mission-critical controls for organizing and navigating complex, deeply nested datasets.

1. GridList (GridList)

  • Contained List Elevation: Elevates enterprise contained lists to RAC’s accessible grid specification.
  • Key Features:
    • Roving arrow-key navigation with multi-item selection (Shift+Click, Cmd+A).
    • Drag-and-drop item reordering handles with accessible keyboard reordering (Alt+Arrow Up/Down).
    • Infinite scroll trigger (GridList.LoadMore) and custom empty state slots.
  • Row Heights: sm: 36px, md: 44px (Frame standard), lg: 56px.

2. Tree & TreeView (Tree)

  • Motivation: Dedicated hierarchical navigator for file systems, organization charts, code AST explorers, and documentation sidebars.
  • Anatomy: 
    <Tree aria-label="Project Structure" selectionMode="multiple">
  <Tree.Item id="src" textValue="src">
    <Tree.Chevron />
    <Tree.Content>src</Tree.Content>
    <Tree.Item id="components">
      <Tree.Chevron />
      <Tree.Content>components</Tree.Content>
    </Tree.Item>
  </Tree.Item>
</Tree>
  • Accessibility: Full treegrid semantics with guide lines, automated branch expansion, and asynchronous dynamic child loading.

3. Sheet (Sheet)

  • Motivation: Integrates RAC 1.22’s native mobile bottom sheet and sliding side panel.
  • Features: Smooth velocity gesture dragging, snap points (e.g. 25%, 50%, 90%, full), backdrop dimming, and viewport-aware responsive breakpoints.

4. Resizable Table & Infinite Scroll

  • Enhancements: Introduces TableLoadMoreItem for infinite datasets and elevated ColumnResizer handles with keyboard nudging (Arrow Left/Right) and minimum width snapping.

Phase 5: Creative Color Suite & High-Scale Virtualization

Phase 5 equips Hashti for specialized creative tooling, canvas design apps, and massive data scale.

1. Color Suite (ColorSuite)

A comprehensive, accessible 8-component suite for parsing, selecting, and manipulating colors in CSS formats (Hex, RGB, HSL, HSB):

ComponentResponsibility
ColorPickerTop-level coordinator popover combining swatch trigger and multi-channel editor.
ColorArea2D saturation/value surface with 2-axis keyboard thumb.
ColorSlider1D channel slider with dynamic gradient track (Hue, Alpha, Lightness).
ColorWheel360° circular hue selector with circular drag constraints.
ColorFieldFormat-aware text input with automated validation and unit parsing.
ColorSwatchColor preview tile with transparency checkerboard background.
ColorSwatchPickerAccessible grid of pre-defined palette swatches.
ColorThumbDual-ring high-contrast drag handle adhering to WCAG focus standards.

2. Virtualizer (Virtualizer)

  • Integration: Powered by @react-aria/virtualizer for Table, GridList, and ListBox.
  • Target Performance: Renders 100,000+ items smoothly at 60fps with sub-16ms layout calculations, dynamic row height measurement, and minimal memory footprint.

3. TokenField (TokenField)

  • Description: Multi-token tag input field supporting keyboard deletion, drag sorting, email validation, and async search suggestions.

Production Verification & Quality Gates

Every elevated component must satisfy Hashti’s four non-negotiable release gates before merging into @hashti/react:

1. Automated Accessibility Audit (Axe Core)

  • Zero Violations: Automated clean sweep across color-contrast, aria-roles, aria-allowed-attr, aria-required-children, and nested-interactive.
  • Live Region Announcements: Status changes and drag reordering must announce cleanly through polite live regions (aria-live="polite").

2. RTL & Internationalization Parity

  • Linguistic Symmetry: Zero margin/padding inversions using hardcoded left/right. Components must use CSS logical properties (margin-inline-start, padding-inline-end).
  • Typography: Seamless font switching to Vazirmatn under Persian/Arabic locales with verified baseline alignment.

3. Token & Theme Fidelity

  • 8-Theme Test Suite: Visual regression confirmation across all 8 themes (white, g10, g90, g100, relay-light, relay-dark, frame-light, frame-dark).
  • 3-Layer Depth: Verification that surfaces, borders, and text maintain required contrast across Layer 0, Layer 1, and Layer 2.

4. Bundle Efficiency

  • Strict Tree-Shaking: Components must remain independently importable without pulling unneeded dependencies.
  • Target Footprint: Zero runtime CSS-in-JS dependencies; prebuilt CSS classes bound directly to CSS variables.
