Hi HN,I built Verani, an experimental realtime SDK for Cloudflare Actors (Durable Objects).The goal is to bring a familiar, event-based DX (rooms, emit, channels, lifecycle hooks) to Cloudflare Durable Objects, while handling hibernation correctly.It focuses on - Socket.io-like semantics on top of Durable Objects - Proper Actor hibernation handling (WebSockets survive, state is restored) - Typed API with explicit tradeoffs.It’s early and experimental, but functional. I built it mainly to explore DX and state management patterns on Cloudflare Actors, and I’d love feedback from people who’ve built realtime systems or used Durable Objects.

Could you build this?
Partial Providing a basic WebSocket interface is doable, but architecting a reliable Socket.io-compatible SDK on Cloudflare Durable Objects that correctly manages DO hibernation lifecycles, cross-node broadcasting, and room state persistence requires deep distributed systems knowledge.
What it would actually take: The SDK must be built in TypeScript atop Cloudflare Workers and Durable Objects, implementing WebSocket hibernation APIs (`ctx.getWebSockets()`) to avoid idle memory billing. The complex part is handling distributed pub/sub state synchronization across multiple Durable Objects, graceful reconnections, backpressure, and message delivery guarantees under edge networking constraints.
