MyCloud

MyCloud is a multi‑user cloud storage web application that I built from scratch. It allows users to sign up, upload files of any size, organise them into folders, preview media, share files with other users, and manage file versions.

Technologies

• Frontend: SvelteKit, Tailwind CSS, Lucide icons
• Backend / Auth: Supabase (PostgreSQL, Row‑Level Security)
• File Storage: Cloudflare R2 (S3‑compatible, presigned uploads)
• Deployment: Vercel (CI/CD, custom domain)
• Version Control: Git & GitHub

Key Features

• User authentication (sign‑up, login, password reset)
• Drag‑and‑drop uploads of any size
• Folders & breadcrumb navigation
• File sharing with other users via email
• Automatic file versioning
• Search, thumbnails, full‑screen previews (images, video, PDF)
• Dark/light mode, responsive design
• Multi‑select operations (delete, rename, copy share links)

Challenges Overcome

Svelte 5 migration – Updated event handlers and used $state runes.
Row‑Level Security – Recreated Supabase storage policies for proper isolation.
Anonymous sign‑in error – Replaced client call with direct REST API request.
Large file uploads – Integrated R2 to bypass 50MB limit via presigned URLs.
Deployment caching – Added cache‑buster and Vercel configuration.
