# ImgBB WebP Uploader

A React package that simplifies uploading images to ImgBB with automatic WebP conversion to reduce file size. Created and maintained by [Qrinux](https://qrinux.com/).

## Features

- 🖼️ **WebP Conversion** - Automatically converts images to WebP format before uploading
- 📊 **Progress Tracking** - Real-time progress updates for both conversion and upload
- 📏 **Size Comparison** - Shows file size before and after WebP conversion
- 🧩 **Multiple Integration Options** - Use as a React component, hook, or direct API

## Installation

```bash
npm install imgbb-webp-uploader
# or
yarn add imgbb-webp-uploader
```

## Usage

### 1. React Component

The simplest way to use the package is with the included React component:

```jsx
import React from 'react';
import { ImgBBUploader } from 'imgbb-webp-uploader';

function App() {
  return (
    <div>
      <h1>Image Upload</h1>
      <ImgBBUploader 
        apiKey="YOUR_IMGBB_API_KEY"
        onSuccess={(response) => console.log('Upload successful:', response)}
        onError={(error) => console.error('Upload failed:', error)}
      />
    </div>
  );
}
```

### 2. React Hook

For more control over the UI, use the hook:

```jsx
import React from 'react';
import { useImgBBUploader } from 'imgbb-webp-uploader';

function CustomUploader() {
  const {
    selectedFile,
    previewUrl,
    isUploading,
    uploadedImage,
    error,
    progress,
    originalSize,
    webpSize,
    sizeReduction,
    handleFileChange,
    uploadImage,
    resetUpload
  } = useImgBBUploader({
    apiKey: "YOUR_IMGBB_API_KEY",
    webpQuality: 0.8,
    maxWidth: 1920
  });

  return (
    <div>
      <input type="file" onChange={handleFileChange} />
      
      {previewUrl && (
        <img src={previewUrl} alt="Preview" style={{ maxWidth: '300px' }} />
      )}
      
      {isUploading && <p>Uploading: {progress}%</p>}
      
      <button onClick={uploadImage} disabled={!selectedFile || isUploading}>
        Upload
      </button>
      
      {uploadedImage && (
        <div>
          <p>Image URL: {uploadedImage.url}</p>
          <p>Size reduction: {sizeReduction}%</p>
        </div>
      )}
    </div>
  );
}
```

### 3. Direct API

For non-React applications or more advanced use cases:

```javascript
import { uploadToImgBB } from 'imgbb-webp-uploader';

async function uploadImage(file) {
  try {
    const response = await uploadToImgBB(file, {
      apiKey: "YOUR_IMGBB_API_KEY",
      convertToWebP: true,
      webpQuality: 0.8,
      maxWidth: 1920,
      onProgress: (progress) => {
        console.log(`Upload progress: ${progress}%`);
      }
    });
    
    console.log('Upload successful:', response);
  } catch (error) {
    console.error('Upload failed:', error);
  }
}

// Use with file input
document.getElementById('fileInput').addEventListener('change', (e) => {
  const file = e.target.files[0];
  if (file) {
    uploadImage(file);
  }
});
```

### 4. React Hook Form Integration

To use with `react-hook-form`, first install the required dependencies:

```bash
npm install react-hook-form imgbb-webp-uploader
```

Here's an example implementation:

```typescript
import React from 'react';
import { useForm, Controller } from 'react-hook-form';
import { ImgBBUploader } from 'imgbb-webp-uploader';

interface FormValues {
  image: string;
}

const ReactHookFormExample = () => {
  const { control, handleSubmit } = useForm<FormValues>();

  const onSubmit = (data: FormValues) => {
    console.log('Form submitted with image URL:', data.image);
  };

  return (
    <form onSubmit={handleSubmit(onSubmit)}>
      <Controller
        name="image"
        control={control}
        defaultValue=""
        render={({ field }) => (
          <ImgBBUploader
            apiKey="your-api-key"
            onUploadComplete={(response) => {
              field.onChange(response.url);
            }}
          />
        )}
      />
      
      <button type="submit">Submit</button>
    </form>
  );
};

export default ReactHookFormExample;
```
