Durability
Alarm-backed operation execution with persistence, retries, concurrency controls, and typed results.
Shirei
Small, sharp tools for stateful systems on Cloudflare Workers.
Packages
Section titled “Packages”DO Transforms
Compose typed caller and callee behavior around Durable Object and Worker RPC calls.
Client-side DO
Typesafe WebSocket RPC, subscriptions, optimistic state, and TanStack DB synchronization.
Big Marge
A registry-delivered Durable Object runtime and browser client that demonstrate the full install path.
One stack, four focused tools
Section titled “One stack, four focused tools”Shirei packages stay close to Cloudflare primitives. Use only the layer you need:
- Big Marge scaffolds a complete runtime and client through the Workers Registry.
- Client-side DO connects browser state to a Durable Object over typesafe WebSocket RPC.
- DO Transforms adds cross-cutting behavior to native RPC without changing domain methods.
- Durability persists background operations and resumes them through Durable Object alarms.
These packages are under active development. The documentation follows the current package branches and calls out delivery guarantees and platform limits rather than hiding them.
