Problem

Files needed to be shared securely on the web with time-limited access — without dedicated servers or idle infrastructure.

Approach

We designed the backend first on Cloudflare Workers, R2, and D1 — APIs, file storage, and link metadata with expiration — then built a focused SvelteKit frontend on Pages.

Architecture

Workers API → R2 storage → D1 metadata → SvelteKit UI — a compact edge architecture with no idle servers.

  1. Workers API
  2. R2 storage
  3. D1 metadata
  4. SvelteKit UI

Stack

Cloudflare Workers for API logic, R2 for file storage, D1 for link metadata and expiration, and SvelteKit on Cloudflare Pages for the web interface.

  • Cloudflare Workers, D1 & R2
  • SvelteKit

Outcome

Ralink runs in production on Cloudflare’s edge: share files with expiring links, distributed globally and efficient to operate.
