import { createThumbnail } from 'react-native-create-thumbnail';

export default function CreateThumbnailDemo() {

  const [text, setText] = useState('');

      <View style={styles.titleArea}>
        <Text style = {styles.title}>Math</Text>
      </View>

      </View>
      <ScrollView style={styles.scrollView}>

Link

Currently, HarmonyOS does not support AutoLink. Therefore, you need to manually configure the linking.

Open the harmony directory of the HarmonyOS project in DevEco Studio.

1. Adding the overrides Field to oh-package.json5 File in the Root Directory of the Project

{
  ...
  "overrides": {
    "@rnoh/react-native-openharmony" : "./react_native_openharmony"
  }
}

2. Introducing Native Code

Currently, two methods are available:

Method 1 (recommended): Use the HAR file.

[!TIP] The HAR file is stored in the harmony directory in the installation path of the third-party library.

Open entry/oh-package.json5 file and add the following dependencies:

"dependencies": {
    "@rnoh/react-native-openharmony": "file:../react_native_openharmony",
    "@react-native-oh-tpl/react-native-create-thumbnail": "file:../../node_modules/@react-native-oh-tpl/react-native-create-thumbnail/harmony/createThumbnail.har"
  }

Click the sync button in the upper right corner.

Alternatively, run the following instruction on the terminal:

cd entry
ohpm install

Method 2: Directly link to the source code.

[!TIP] The source code is located in the harmony folder within the installation path of the third-party library.

Open entry/oh-package.json5 file and add the following dependencies:

"dependencies": {
    "@rnoh/react-native-openharmony": "file:../react_native_openharmony",
    "@react-native-oh-tpl/react-native-create-thumbnail": "file:../../node_modules/@react-native-oh-tpl/react-native-create-thumbnail/harmony/createThumbnail"
  }

run the following instruction on the terminal:

cd entry
ohpm install --no-link

3. Introducing BlobUtilPackage to ArkTS

Open the entry/src/main/ets/RNPackagesFactory.ts file and add the following code:

  ...
+ import { CreateThumbnailPackage } from '@react-native-oh-tpl/react-native-create-thumbnail/ts';

export function createRNPackages(ctx: RNPackageContext): RNPackage[] {
  return [
    new SamplePackage(ctx),
+   new CreateThumbnailPackage(ctx)
  ];
}

4. Running

Click the sync button in the upper right corner.

Alternatively, run the following instruction on the terminal:

cd entry
ohpm install

Then build and run the code.
