Instructure UI (InstUI) - React Component Library

• version 11.6.0
• Instructure UI (InstUI) is a comprehensive React component library.

Documentation

User Guides

Getting Started

• Accessibility: Instructure UI targets WCAG 2.1 AA/AAA standards with proper color contrast, keyboard navigation, screen reader support, and ARIA compliance. Components are perceivable, operable, understandable, and robust.
• Theming components: InstUI has two themes:

  canvas

  (default) and

  canvas-high-contrast

  . Colors are layered: primitives (base), contrasts (theme-specific), and UI (curated tokens). Use

  InstUISettingsProvider

  to set themes. Overrides allow customization but must maintain accessibility.
• Usage: Quick start: Create a React app, add

  @instructure/ui

  , wrap with

  InstUISettingsProvider

  , and use components. Integrate with existing projects by adding the dependency and provider. Read about theme overrides and accessibility for best practices.

Guides

• Accessing the dom: Guidance for properly accessing DOM elements in React components using refs instead of findDOMNode to avoid warnings. Examples show good and bad patterns for component ref handling.
• Color system: Color system divided into primitive (hex values) and semantic (contextual) colors. Includes data visualization palette with primary and secondary hues for charts and graphs on white backgrounds.
• Focus management: Comprehensive focus management system for dialogs, modals, and popovers. Uses Dialog component with FocusRegion and FocusRegionManager to trap focus, handle escape keys, and manage screen reader accessibility.
• Form errors: InstUI form components use a

  messages

  prop for error/hint/success messages. Supports both

  error

  (legacy) and

  newError

  (accessible) types. Required fields now show an asterisk automatically. Examples provided for various form components like TextInput, Checkbox, and DateTimeInput.
• Layout spacing: InstUI provides semantic spacing tokens (e.g., buttons, tags) for consistent layouts. Apply spacing via

  margin

  prop, container

  gap

  , or importing from theme. Legacy tokens are available for compatibility but not recommended for new layouts.
• Module federation: InstUI supports module federation with specific version requirements. For v10.14+, use local themes (

  canvasThemeLocal

  ). For older hosts, guest apps must use v10.14+ and local themes. Global theme overrides don't apply to local themes.
• Server side rendering: SSR with Next.js requires wrapping the app with

  InstUISettingsProvider

  for deterministic ID generation. Avoid

  @instructure/ui

  meta-package; install only needed packages. CodeEditor isn't SSR-compatible and must be dynamically imported.
• Typography system: Use

  <Text>

  and

  <Heading>

  components with semantic variants for consistent typography. Variants define font style, weight, size, and line height. Legacy tokens (e.g., fontSizeXSmall) are deprecated and should not be used in new designs.
• Using theme overrides: Customize components via theme overrides while ensuring WCAG compliance. Use nested

  InstUISettingsProvider

  for subtree themes, override global or component themes, and leverage branding variables for user customization. Deprecated global theming causes issues with multiple InstUI versions.

Patterns

• Content alignment: Guidelines for main content area alignment with maximum width (948px) for readability, minimum width (320px) for accessibility, and responsive padding (24px/12px). Ensures proper centering, avoids two-dimensional scrolling, and allows exceptions for complex data displays.
• Destroy action: A modal used for irreversible actions like deletion. Includes guidelines for usage: use clear language, avoid vague confirmations, and use a danger button for the destructive action.
• Search: Provides search input patterns including auto-activated, activated, and autocomplete search. Includes guidelines, accessibility support, and clear state management examples.
• Using icons: Guidelines for using icons with proper accessibility roles, size variants, and color options. Line icons for light backgrounds, solid for dark backgrounds. Icons scale with parent font-size by default.

Components

• InstUISettingsProvider: A global configuration component for applying themes and text direction settings across an application. It wraps Emotion's ThemeProvider and supports nested providers for theme inheritance and overrides. Also manages text direction (LTR/RTL) via context for descendant components.
• Alert: Notifies users with contextual variants (success, info, error, warning). Supports dismissible dialogs, automatic timeout dismissal, live regions for screen readers, and inline usage without shadows. Includes accessibility guidelines for proper implementation.
• Avatar: Displays user avatars with fallback to initials or icons. Supports circle/rectangle shapes, multiple sizes, colors, and inverse styling. Includes special AI avatar variant and accessibility considerations with aria-hidden attribute.

Utilities

• BaseButton: Low-level utility component for composing Instructure UI buttons. Not intended for direct use; developers should use Button, CloseButton, IconButton, or CondensedButton instead.
• Dialog: A utility component for accessibility in modals, popovers, and trays. Manages focus trapping, screen reader visibility, and keyboard navigation. Essential for WCAG-compliant modal interactions.
• Expandable: Handles expand/collapse functionality for components like ToggleDetails and ToggleGroup. Provides props for accessibility and event handling. Manages state for expanded content visibility.
• Focusable: A utility component that detects when elements receive focus. Provides render props for creating accessible focus-based interactions, such as skip-to-content links or focus-triggered tooltips. Ensures WCAG compliance for focus management.
• Transition: A wrapper component for transitioning elements in and out of the UI. Supports fade, scale, and slide transitions with customizable directions. Handles mount/unmount transitions and supports RTL mirroring for slide animations.
• Options: A view-only component for building option lists or menus. Supports variants (default, highlighted, selected, disabled), icons, nesting, and custom roles. Does not manage state—requires external event handling.
• Mask: A component that covers its nearest positioned parent element. Can be used fullscreen within a Portal and supports click-to-close functionality. Useful for overlays and blocking UI interactions.
• Portal: Renders a React subtree into a different DOM element. Useful for modal-like components that need to break out of parent containers. Typically used with Overlay, Modal, or other components that need to render outside their parent hierarchy.
• Position: Positions content relative to a target element with various placement options. Supports RTL internationalization, offset adjustments, and mounting in specific DOM nodes. Replaces older Target/Content pattern with renderTarget prop.
• Selectable: Low-level utility for building custom combobox widgets. Provides ARIA-compliant prop getters and state management hooks. Use existing Select component when possible.
• InlineSVG: Renders accessible SVG content inline with support for fixed dimensions or container filling. Differentiates from SVGIcon by being suitable for non-icon SVG graphics while maintaining accessibility standards.
