File Upload Fields

When creating a file upload field, you get a complete file management system automatically. Files are stored securely in the cloud and delivered via CDN for lightning-fast access worldwide.

Setting up file uploads:

Choose File Upload as your field type
Configure allowed file types and size limits
Set public/private access permissions
Define upload quantity limits

Your file field will display as an intuitive drag-and-drop interface with upload progress, file previews, and management controls.

File Types & Display

Configure your file field to handle specific content types:

Images - JPG, PNG, GIF, WebP, SVG with automatic thumbnail generation and gallery display

Documents - PDFs with built-in viewer, Word documents, Excel spreadsheets with preview support

All Files - Accept any file type for maximum flexibility

Custom Types - Define your own allowed file extensions and MIME types

File Storage & Delivery

Every uploaded file gets:

Unique storage key for secure file identification
CDN distribution for global fast delivery
Automatic optimisation for web performance
Metadata tracking including size, type, and upload date

Files are accessible via clean CDN URLs:

http

https://cdn.anythink.cloud/org/{your-org-id}/files/{storage-key}

Public vs Private Files

Public Files - Accessible to anyone with the URL, perfect for images, marketing materials, and public documents. These files are cached globally for maximum performance.

Private Files - Require authentication to access, ideal for user documents, sensitive content, or premium resources. Access is controlled through your API permissions.

File Operations

Your file explorer includes everything you need:

Drag & Drop Upload - Simply drag files or click to browse
Bulk Selection - Select multiple files for batch operations
File Preview - Click any file to view or download
Search & Filter - Find files by name or type instantly
Copy Public Links - Get direct CDN URLs for sharing

API Integration

Files integrate seamlessly with your API. When you fetch an entity with file relationships, you get structured data:

json

{
  "images": {
    "__data": [
      {
        "id": 2,
        "file_name": "optimized-filename.jpeg",
        "file_size": 2049732,
        "file_type": "image/jpeg",
        "is_public": true,
        "storage_key": "31606ea3ebdd42e8b7494fce4fbb136e.jpeg",
        "original_file_name": "My Original Photo.jpeg"
      }
    ],
    "__count": 1
  }
}

Security & Limits

Every file upload includes:

Configurable size limits to prevent abuse
File type validation to ensure only allowed formats
Upload quantity limits to control storage usage

Performance Features

Best Practices

File Organisation - Use descriptive filenames and separate file fields for different content types

Size Management - Keep images under 2MB and documents under 5MB for optimal performance

Access Control - Use private files for sensitive content, public files for assets that need to be cached
