Pastebin R2
A pastebin on Cloudflare Workers in TypeScript with Hono, storing objects in R2 behind a small REST API — create, update, list, info, delete — with syntax-highlighted and plain-text views, and pastes that expire on their own.
The problem
Provide a small paste service whose objects expire predictably, without introducing a separate application server or database for the paste bodies.
Architecture
- Hono routes the API and browser interface in a Cloudflare Worker.
- R2 stores paste bodies and their TTL in custom metadata.
- Reads enforce expiry immediately while an hourly cron sweeps what is left.
Highlights
- Syntax-highlighted and plain-text views
- Configurable lifetimes capped at 48 hours
- A Nix flake for dev and build, and a live instance at paste.codebam.ca
