🔧 Advanced Configuration Options

interface MinioOptions {
  // Required Basic Configuration
  endpoint: string;        // MinIO server endpoint
  cdn_url: string;         // CDN URL for public files
  bucket: string;          // Default public bucket
  access_key_id: string;   // MinIO access key
  secret_access_key: string; // MinIO secret key

}

Customization Examples

Custom File Key Generation

buildKey: (file) => {
  // Generate custom file path/key
  return `uploads/${new Date().toISOString()}/${file.originalName}`;
}

Custom Metadata

uploadMetadata: (file) => ({
  'x-amz-meta-my-key': 'custom-value',
  'content-type': file.mimetype
})

🌐 Environment Variables

Required Environment Variables:

• MINIO_ENDPOINT: MinIO server URL
• MINIO_CDN_URL: CDN endpoint for public files
• MINIO_BUCKET: Default public bucket name
• MINIO_ACCESS_KEY: MinIO access key
• MINIO_SECRET_KEY: MinIO secret key

Optional Environment Variables:

• MINIO_PRIVATE_BUCKET: Separate private bucket name

🛡️ Security Considerations

• Use strong, unique access keys
• Implement bucket-level access controls
