webp

To convert a Base64 string to a WebP image in TypeScript, you can use the `webp-converter` library. Here's a step-by-step guide:

1. **Install the `webp-converter` library**:
```bash
npm install webp-converter
```

2. **Create a TypeScript function to handle the conversion**:
```typescript
import * as fs from 'fs';
import * as webp from 'webp-converter';

async function base64ToWebP(base64Str: string, outputPath: string): Promise {
// Convert Base64 string to buffer
const buffer = Buffer.from(base64Str, 'base64');

// Write buffer to a temporary file
const tempFilePath = 'temp_image.png';
fs.writeFileSync(tempFilePath, buffer);

// Convert the temporary file to WebP format
await webp.cwebp(tempFilePath, outputPath, '-q 80');

// Clean up the temporary file
fs.unlinkSync(tempFilePath);
}

// Example usage
const base64Str = 'your_base64_string_here';
const outputPath = 'output_image.webp';
base64ToWebP(base64Str, outputPath).then(() => {
console.log('Conversion complete!');
}).catch((error) => {
console.error('Error during conversion:', error);
});
```

This script does the following:
1. Converts the Base64 string to a buffer.
2. Writes the buffer to a temporary file.
3. Uses `webp-converter` to convert the temporary file to a WebP image.
4. Deletes the temporary file after conversion.

Feel free to adjust the quality parameter (`-q 80`) to suit your needs. If you have any questions or need further assistance, let me know!
