What this skill does
S3 Upload Handler Skill This skill provides methods to handle file uploads to AWS S3 using pre-built UI components, custom client-side logic, or server-side processing. Capabilities 1. UI Component: Ready-to-use S3Uploader for drag-and-drop or button uploads. 2. Client SDK: ClientS3Uploader class for custom upload interfaces. 3. Server Utilities: uploadFromServer for backend file processing and uploading. Usage Patterns 1. Standard UI Component (Recommended) Use the S3Uploader component for most user-facing upload needs. 2. Custom Client-Side Upload Use ClientS3Uploader when you need full control over the UI (e.g., hidden inputs, custom buttons). 3. Server-Side Upload Use uploadFromServer in API routes or Server Actions for processing files (resizing, generating PDFs) before storage. Environment Configuration Ensure .env.local has the necessary AWS credentials: API Route Example (for Presigned URLs) You typically need an API route to generate presigned URLs for the client uploader. Refer to reference.md for more details.
