TanStack Hotkeys (React)

Type-safe keyboard shortcut management for React. Package: @tanstack/react-hotkeys.

All framework packages re-export everything from @tanstack/hotkeys core — no separate install needed.

Quick Start

import { useHotkey } from '@tanstack/react-hotkeys'

function App() {
  useHotkey('Mod+S', () => saveDocument())
  return <div>Press Cmd+S (Mac) or Ctrl+S (Windows) to save</div>
}

Mod resolves to Meta (Cmd) on macOS, Control on Windows/Linux.

Core Hooks

useHotkey(hotkey, callback, options?)

Primary hook. Accepts string ('Mod+S') or RawHotkey object ({key: 'S', mod: true}).

Callback receives (event: KeyboardEvent, context: {hotkey, parsedHotkey}).

Auto-syncs callback every render (no stale closures). Auto-cleans up on unmount.

// String form
useHotkey('Mod+S', () => save())

// Object form
useHotkey({ key: 'S', mod: true }, () => save())

// Conditional
useHotkey('Escape', () => onClose(), { enabled: isOpen })

// Scoped to element (must be focusable — add tabIndex)
const ref = useRef<HTMLDivElement>(null)
useHotkey('Escape', () => close(), { target: ref })

Default options:

useHotkeySequence(sequence, callback, options?)

Vim-style multi-key sequences. Keys pressed in order within timeout.

useHotkeySequence(['G', 'G'], () => scrollToTop())
useHotkeySequence(['D', 'I', 'W'], () => deleteInnerWord(), { timeout: 500 })

// With modifiers
useHotkeySequence(['Mod+K', 'Mod+C'], () => commentSelection())

Options: timeout (default 1000ms), enabled (default true).

Overlapping prefixes work — manager tracks each independently.

useHotkeyRecorder(options)

Record custom shortcuts. Returns {isRecording, recordedHotkey, startRecording, stopRecording, cancelRecording}.

• Escape cancels recording
• Backspace/Delete clears recorded hotkey
• Auto-converts to portable Mod format (Meta+S becomes Mod+S)

const recorder = useHotkeyRecorder({
  onRecord: (hotkey) => setShortcut(hotkey),
  onCancel: () => console.log('cancelled'),
  onClear: () => console.log('cleared'),
})

Key State Tracking

// All held keys
const heldKeys = useHeldKeys() // string[]

// Single key check (optimized — only re-renders when this key changes)
const isShiftHeld = useKeyHold('Shift') // boolean

// Key-to-code mapping (distinguish left/right modifiers)
const codes = useHeldKeyCodes() // Record<string, string>

Display Formatting

import { formatForDisplay, formatWithLabels } from '@tanstack/react-hotkeys'

// Platform-aware symbols
formatForDisplay('Mod+S')        // Mac: "⌘S" | Windows: "Ctrl+S"
formatForDisplay('Mod+Shift+Z')  // Mac: "⇧⌘Z" | Windows: "Ctrl+Shift+Z"

// Text labels
formatWithLabels('Mod+S')        // Mac: "Cmd+S" | Windows: "Ctrl+S"

Use in UI:

<button>Save <kbd>{formatForDisplay('Mod+S')}</kbd></button>

HotkeysProvider

Set global defaults for all hooks. Per-hook options override.

import { HotkeysProvider } from '@tanstack/react-hotkeys'

<HotkeysProvider defaultOptions={{
  hotkey: { preventDefault: true },
  hotkeySequence: { timeout: 1500 },
  hotkeyRecorder: { onCancel: () => console.log('cancelled') },
}}>
  <App />
</HotkeysProvider>

Devtools

npm install @tanstack/react-devtools @tanstack/react-hotkeys-devtools

import { TanStackDevtools } from '@tanstack/react-devtools'
import { hotkeysDevtoolsPlugin } from '@tanstack/react-hotkeys-devtools'

<TanStackDevtools plugins={[hotkeysDevtoolsPlugin()]} />

Auto-excluded from production builds. Use @tanstack/react-hotkeys-devtools/production import to include in prod.

Key Patterns

• Scoped hotkeys: Pass target: ref + ensure element has tabIndex
• Conditional: Use enabled option tied to state
• Multiple hotkeys: Each useHotkey call is independent
• Shortcut settings UI: Combine useHotkeyRecorder + useHotkey with dynamic bindings + formatForDisplay
• Hold-to-reveal UI: Use useKeyHold to conditionally render elements
• Shortcut hints overlay: Show overlay when modifier held via useKeyHold
