useKeyboard Hook

Overview

The useKeyboard hook is designed for React Native applications to easily manage and respond to keyboard events. It provides information about the keyboard's visibility and height, which can be used to adjust the layout or behavior of your application when the keyboard is shown or hidden.

Features

• 🎯 Real-time keyboard visibility tracking
• 📏 Accurate keyboard height measurements
• 🔄 Platform-specific event handling (iOS & Android)
• ⚙️ Customizable keyboard events
• 🪶 Lightweight with zero dependencies
• 💪 Written in TypeScript with full type support

Installation

npm install react-native-use-keyboard
# or
yarn add react-native-use-keyboard
# or
pnpm install react-native-use-keyboard
# or
bun install react-native-use-keyboard

Usage

import { useKeyboard } from "react-native-use-keyboard";

const MyComponent = () => {
  const { isVisible, height } = useKeyboard();

  return (
    <View style={{ flex: 1 }}>
      <View style={{ flex: 1 }}>
        <Text>My Component</Text>
      </View>
      {isVisible && (
        <View style={{ height }}>
          <Text>Keyboard is visible</Text>
        </View>
      )}
    </View>
  );
};

With Custom Events

const MyComponent = () => {
  const { isVisible, height } = useKeyboard({
    show: "keyboardDidShow", // custom show event
    hide: "keyboardDidHide", // custom hide event
  });
  // ... rest of your component
};

API

useKeyboard(customEvents?: CustomEvents): KeyboardInfo

Parameters

• customEvents (optional): An object to customize the keyboard event names.
  • show: A KeyboardEventName to specify a custom event name for keyboard show events
  • hide: A KeyboardEventName to specify a custom event name for keyboard hide events

Return Value

Returns an object with:

• isVisible: boolean - Indicates if the keyboard is currently visible
• height: number - Current height of the keyboard in pixels (0 when hidden)

Platform Specific Behavior

By default, the hook uses different events for iOS and Android:

• iOS: Uses 'keyboardWillShow' and 'keyboardWillHide'
• Android: Uses 'keyboardDidShow' and 'keyboardDidHide'

Common Use Cases

Adjusting Screen Content

const MyScreen = () => {
  const { isVisible, height } = useKeyboard();

  return (
    <View style={{ flex: 1 }}>
      <ScrollView
        contentContainerStyle={{
          paddingBottom: isVisible ? height : 0,
        }}
      >
        {/* Your content */}
      </ScrollView>
    </View>
  );
};

Animating Views with Keyboard

const MyAnimatedComponent = () => {
  const { isVisible, height } = useKeyboard();
  const translateY = useRef(new Animated.Value(0)).current;

  useEffect(() => {
    Animated.timing(translateY, {
      toValue: isVisible ? -height : 0,
      duration: 250,
      useNativeDriver: true,
    }).start();
  }, [isVisible, height]);

  return (
    <Animated.View style={{ transform: [{ translateY }] }}>
      {/* Your content */}
    </Animated.View>
  );
};
