Usage

Basic Example

Import and use the library in your React Native app:

import React from 'react';
import { Button, View } from 'react-native';
import { HapticPatterns } from 'react-native-haptic-patterns';

const MyComponent = () => {
  const handlePress = async () => {
    try {
      // Check if device supports haptics
      const isSupported = await HapticPatterns.checkForHapticSupport();

      if (isSupported) {
        // Play a 200ms haptic pattern
        HapticPatterns.playHapticPattern(200);
      } else {
        console.log('Haptics not supported on this device');
      }
    } catch (error) {
      console.error('Haptic error:', error);
    }
  };

  return (
    <View>
      <Button onPress={handlePress} title="Feel the Haptic" />
    </View>
  );
};

Quick Start

import { HapticPatterns } from 'react-native-haptic-patterns';

// Check haptic support
const isSupported = await HapticPatterns.checkForHapticSupport();

// Play a simple haptic pattern
HapticPatterns.playHapticPattern(200); // Vibrate for 200ms

// Stop the current haptic pattern
HapticPatterns.stopHapticPattern();

// Play a recorded pattern
const recordedEvents = [
  { startTime: 0, endTime: 100, isPause: false },
  { startTime: 100, endTime: 200, isPause: true },
  { startTime: 200, endTime: 400, isPause: false },
];

await HapticPatterns.playRecordedPattern(recordedEvents);

Advanced Pattern Example

import {
  HapticPatterns,
  RecordedEventType,
} from 'react-native-haptic-patterns';

const playCustomPattern = () => {
  // Create a custom haptic pattern
  const pattern: RecordedEventType[] = [
    { startTime: 0, endTime: 100, isPause: false }, // Short vibration
    { startTime: 100, endTime: 200, isPause: true }, // Pause
    { startTime: 200, endTime: 400, isPause: false }, // Longer vibration
    { startTime: 400, endTime: 500, isPause: true }, // Pause
    { startTime: 500, endTime: 600, isPause: false }, // Final vibration
  ];

  try {
    HapticPatterns.playRecordedPattern(pattern);
    console.log('Pattern playback completed');
  } catch (error) {
    console.error('Pattern playback error:', error);
  }
};

// Use in different scenarios
const provideSuccessFeedback = () => {
  HapticPatterns.playHapticPattern(50); // Quick tap
};

const provideErrorFeedback = async () => {
  const errorPattern: RecordedEventType[] = [
    { startTime: 0, endTime: 100, isPause: false },
    { startTime: 100, endTime: 150, isPause: true },
    { startTime: 150, endTime: 250, isPause: false },
  ];
  await HapticPatterns.playRecordedPattern(errorPattern);
};

Methods

checkForHapticSupport

checkForHapticSupport(): Promise<boolean>

Checks if the device supports haptic feedback.

Platform behavior:

• Android: Always returns true as Android devices support haptic feedback through the Vibration API.
• iOS: Queries the device's Core Haptics capabilities to determine if haptic feedback is supported.

Returns:

• A Promise that resolves to true if haptics are supported, false otherwise.

playHapticPattern

playHapticPattern(vibrationDuration: number): Promise<void>

Plays a custom haptic pattern for the specified duration.

Parameters:

• vibrationDuration: Duration of the vibration in milliseconds.

Platform behavior:

• Android: Uses the Vibration API.
• iOS: Builds and plays a haptic pattern using Core Haptics.

Returns:

• A Promise that resolves when the pattern has started playing.

stopHapticPattern

stopHapticPattern(): Promise<void>

Stops the currently playing haptic pattern.

Platform behavior:

• Android: Cancels vibration.
• iOS: Stops the HapticEngine player.

Returns:

• A Promise that resolves when the pattern has been stopped.

playRecordedPattern

playRecordedPattern(recordedEvents: RecordedEventType[]): Promise<void>

Plays a recorded haptic pattern.

Parameters:

• recordedEvents: An array of recorded haptic or pause events, each with { startTime, endTime, isPause }.

Platform behavior:

• Android: Converts events to a vibration pattern array and plays it.
• iOS: Converts events to haptic events and plays them using Core Haptics.

Returns:

• A Promise that resolves when the entire pattern has finished playing.

Types

RecordedEventType

Represents a single event in a recorded haptic pattern.

interface RecordedEventType {
  startTime: number; // Start time in milliseconds
  endTime: number; // End time in milliseconds
  isPause: boolean; // Whether this is a pause (true) or haptic event (false)
}

Example:

const pattern: RecordedEventType[] = [
  { startTime: 0, endTime: 100, isPause: false }, // Vibrate for 100ms
  { startTime: 100, endTime: 200, isPause: true }, // Pause for 100ms
  { startTime: 200, endTime: 300, isPause: false }, // Vibrate for 100ms
];

Examples

To better understand how to use these methods in a real-world scenario, refer to the following full working example project:

Example App: Demonstrates how to record, play, and reset custom haptic patterns using the library's API in a React Native application.

Common Use Cases

Button Press Feedback

<TouchableOpacity
  onPress={() => {
    HapticPatterns.playHapticPattern(50);
    // Handle button action
  }}>
  <Text>Press Me</Text>
</TouchableOpacity>

Success/Error Notifications

const showSuccessNotification = () => {
  HapticPatterns.playHapticPattern(100); // Single haptic
  // Show success message
};

const showErrorNotification = async () => {
  const errorPattern: RecordedEventType[] = [
    { startTime: 0, endTime: 50, isPause: false },
    { startTime: 50, endTime: 100, isPause: true },
    { startTime: 100, endTime: 150, isPause: false },
  ];
  await HapticPatterns.playRecordedPattern(errorPattern);
  // Show error message
};

Long Press Detection

<TouchableOpacity
  onLongPress={() => {
    HapticPatterns.playHapticPattern(150);
    // Handle long press
  }}>
  <Text>Long Press Me</Text>
</TouchableOpacity>

Troubleshooting

iOS

Haptics not working on simulator

• Core Haptics only works on physical devices. Test on a real iPhone (iPhone 8 or newer recommended for best haptic support).

Build errors after installation

• Run cd ios && pod install && cd .. to ensure CocoaPods are properly installed.
• Clean build folder in Xcode: Product > Clean Build Folder (Shift + Cmd + K)
• Delete derived data: rm -rf ~/Library/Developer/Xcode/DerivedData

Haptics not working on device

• Ensure the device supports Core Haptics (iPhone 8 and newer)
• Check that haptic feedback is enabled in device settings
• Verify iOS version is 13.0 or higher

Android

Vibration not working

• Ensure you've added the VIBRATE permission to AndroidManifest.xml
• Check that vibration is enabled in device settings
• Some devices may have battery optimization that affects vibration

Build errors

• Try cleaning the build: cd android && ./gradlew clean && cd ..
• Delete build folders: rm -rf android/app/build
• Invalidate caches in Android Studio: File > Invalidate Caches / Restart

Permission denied errors

• Verify the VIBRATE permission is in the correct location in AndroidManifest.xml
• Check that the permission is not being removed by other configurations

General

Module not found errors

• Ensure the package is properly installed: npm install or yarn install
• Try resetting Metro bundler cache: npx react-native start --reset-cache
• Rebuild the app completely: npx react-native run-ios or npx react-native run-android
