React Native Camscanner Application Mobile Code

React Native is an open-source framework that allows developers to build mobile applications using JavaScript and React. It offers various components and APIs that allow developers to build cross-platform applications for iOS and Android. One such application is CamScanner, which is used to scan and save documents on a mobile device.

Installing CamScanner

The first step to building a CamScanner application in React Native is to install the CamScanner SDK. You can either download it directly from the CamScanner website or use a package manager like npm to install it. Once you have installed the SDK, you can start building your application.

Building the Application

To build the application, you will need to create a new project using the React Native CLI. Once you have created the project, you will need to add the CamScanner SDK to your project by importing it as a module.

import CamScanner from 'camscanner-react-native';

CamScanner.scanDocument().then((imageUri) => {
  console.log(imageUri);
}).catch((error) => {
  console.log(error);
});

The above code snippet shows how you can use the CamScanner SDK to scan a document in your React Native application. The scanDocument() method is used to scan the document, and it returns a promise that resolves with the image URI of the scanned document. You can then use this URI to save the document or display it in your application.

Alternative Approach

Another approach to building a CamScanner application in React Native is to use a third-party library like react-native-document-scanner. This library provides a simple and easy-to-use API for scanning documents in your application.

import DocumentScanner from 'react-native-document-scanner';

class MyComponent extends Component {
  onPictureTaken = (data) => {
    console.log(data);
  }

  render() {
    return (
      <DocumentScanner
        onPictureTaken={this.onPictureTaken}
      />
    );
  }
}

The above code snippet shows how you can use the react-native-document-scanner library to scan a document in your React Native application. The DocumentScanner component is used to scan the document, and it provides a callback function onPictureTaken() that is called when the document is scanned. You can then use the data returned by this function to save or display the scanned document.

Conclusion

Building a CamScanner application in React Native is relatively easy thanks to the various components and APIs available in the framework. By using the CamScanner SDK or a third-party library like react-native-document-scanner, you can create a powerful and feature-rich application that allows users to scan and save documents on their mobile devices.
