@capacitor/keyboard

The Keyboard API provides keyboard display and visibility control, along with event tracking when the keyboard shows and hides.

Install

npm install @capacitor/keyboard
npx cap sync

Example

import { Keyboard } from '@capacitor/keyboard';

Keyboard.addListener('keyboardWillShow', info => {
  console.log('keyboard will show with height:', info.keyboardHeight);
});

Keyboard.addListener('keyboardDidShow', info => {
  console.log('keyboard did show with height:', info.keyboardHeight);
});

Keyboard.addListener('keyboardWillHide', () => {
  console.log('keyboard will hide');
});

Keyboard.addListener('keyboardDidHide', () => {
  console.log('keyboard did hide');
});

Configuration

On iOS, the keyboard can be configured with the following options:

Prop	Type	Description	Default	Since
resize	KeyboardResize	Configure the way the app is resized when the Keyboard appears. Only available on iOS.	native	1.0.0
style	KeyboardStyle	Override the keyboard style if your app doesn't support dark/light theme changes. If not set, the keyboard style will depend on the device appearance. Only available on iOS.		1.0.0
resizeOnFullScreen	boolean	There is an Android bug that prevents the keyboard from resizing the WebView when the app is in full screen (i.e. if StatusBar plugin is used to overlay the status bar). This setting, if set to true, add a workaround that resizes the WebView even when the app is in full screen. Only available for Android		1.1.0

Examples

In capacitor.config.json:

{
  "plugins": {
    "Keyboard": {
      "resize": "body",
      "style": "DARK",
      "resizeOnFullScreen": true
    }
  }
}

In capacitor.config.ts:

/// <reference types="@capacitor/keyboard" />

import { CapacitorConfig } from '@capacitor/cli';
import { KeyboardResize, KeyboardStyle } from '@capacitor/keyboard';

const config: CapacitorConfig = {
  plugins: {
    Keyboard: {
      resize: KeyboardResize.Body,
      style: KeyboardStyle.Dark,
      resizeOnFullScreen: true,
    },
  },
};

export default config;
