Provides haptic feedback to enhance user interactions through physical sensations. The haptics API includes three methods for different types of feedback: impact, notification, and selection.

Usage

import { sdk } from '@farcaster/miniapp-sdk'

// Trigger impact feedback
await sdk.haptics.impactOccurred('medium')

// Trigger notification feedback
await sdk.haptics.notificationOccurred('success')

// Trigger selection feedback
await sdk.haptics.selectionChanged()

Methods

impactOccurred

Triggers impact feedback, useful for simulating physical impacts.

Parameters

type

• Type:'light' | 'medium' | 'heavy' | 'soft' | 'rigid'

The intensity and style of the impact feedback.

• light: A light impact
• medium: A medium impact
• heavy: A heavy impact
• soft: A soft, dampened impact
• rigid: A sharp, rigid impact

Example

import { sdk } from '@farcaster/miniapp-sdk'

// Trigger when user taps a button
await sdk.haptics.impactOccurred('light')

// Trigger for more significant actions
await sdk.haptics.impactOccurred('heavy')

notificationOccurred

Triggers notification feedback, ideal for indicating task outcomes.

Parameters

type

• Type:'success' | 'warning' | 'error'

The type of notification feedback.

• success: Indicates a successful operation
• warning: Indicates a warning or caution
• error: Indicates an error or failure

Example

import { sdk } from '@farcaster/miniapp-sdk'

// After successful action
await sdk.haptics.notificationOccurred('success')

// When showing a warning
await sdk.haptics.notificationOccurred('warning')

// On error
await sdk.haptics.notificationOccurred('error')

selectionChanged

Triggers selection feedback, perfect for UI element selections.

Example

import { sdk } from '@farcaster/miniapp-sdk'

// When user selects an item from a list
await sdk.haptics.selectionChanged()

// When toggling a switch
await sdk.haptics.selectionChanged()

Return Value

All haptic methods return Promise<void>.

Availability

Haptic feedback availability depends on the client device and platform. You can check if haptics are supported using the getCapabilities() method:

import { sdk } from '@farcaster/miniapp-sdk'

const capabilities = await sdk.getCapabilities()

// Check if specific haptic methods are supported
if (capabilities.includes('haptics.impactOccurred')) {
  await sdk.haptics.impactOccurred('medium')
}

if (capabilities.includes('haptics.notificationOccurred')) {
  await sdk.haptics.notificationOccurred('success')
}

if (capabilities.includes('haptics.selectionChanged')) {
  await sdk.haptics.selectionChanged()
}

Best Practices

1. Use sparingly: Overuse of haptic feedback can be distracting
2. Match intensity to action: Use light feedback for minor actions, heavy for significant ones
3. Provide visual feedback too: Not all devices support haptics
4. Check availability: Always verify haptic support before using
5. Consider context: Some users may have haptics disabled in their device settings.
