ReactJS Onsen UI GestureDetector Component

ReactJS Onsen-UI is a popular front-end library with a set of React components that are designed to developing HTML5 hybrid and mobile web apps in a beautiful and efficient way. GestureDetector Component allows the user to detect finger gestures within a wrapped element. We can use the following approach in ReactJS to use the Onsen-UI GestureDetector Component.

GestureDetector Props:

onDrag: It is a callback function that is called when the user drags in any direction.
onDragLeft: It is a callback function that is called when the user drags left.
onDragRight: It is a callback function that is called when the user drags right.
onDragUp: It is a callback function that is called when the user drags up.
onDragDown: It is a callback function that is called when the user drags down.
onHold: It is a callback function that is called when the user holds.
onRelease: It is a callback function that is called when the user releases.
onSwipe: It is a callback function that is called when the user swipes in any direction.
onSwipeLeft: It is a callback function that is called when the user swipes left.
onSwipeRight: It is a callback function that is called when the user swipes right.
onSwipeUp: It is a callback function that is called when the user swipes up.
onSwipeDown: It is a callback function that is called when the user swipes down.
onTap: It is a callback function that is called when the user taps.
onDoubleTap: It is a callback function that is called when the user double taps.
onPinch: It is a callback function that is called when the user pinches in or out.

Creating React Application And Installing Module:

Step 1: Create a React application using the following command:
```
npx create-react-app foldername
```

Step 2: After creating your project folder i.e. foldername, move to it using the following command:
```
cd foldername
```
Step 3: After creating the ReactJS application, Install the required module using the following command:
```
npm install onsenui react-onsenui 
```

Project Structure: It will look like the following.

Project Structure

Example: Now write down the following code in the App.js file. Here, App is our default component where we have written our code.

App.js

import React from 'react'; 

import 'onsenui/css/onsen-css-components.css'; 

import { GestureDetector } from 'react-onsenui'; 

export default function App() { 

    return ( 

        <div style={{ 

            display: 'block', width: 500, paddingLeft: 30 

        }}> 

            <h6>ReactJS Onsen-UI GestureDetector Component</h6> 

            <GestureDetector 

                onTap={() => console.log('You just tapped!!')} 

                onDragRight={() => console.log('You just dragged Right!!')} 

            > 

                <div style={{ backgroundColor: 'green',  

                width: '500px', height: '300px' }}> 

                    Make your Gesture here! 

                </div> 

            </GestureDetector> 

        </div> 

    ); 
}

Step to Run Application: Run the application using the following command from the root directory of the project:

npm start

Output: Now open your browser and go to http://localhost:3000/, you will see the following output:
