First release · 0.4.0
Effect streams, from server to browser.
Streamsy is an Effect server and toolkit for Durable Streams. Create typed event streams, follow their changes, and serve them to official Durable Streams browser clients.
@streamsy/core
Typed stream declarations, HTTP routes, storage contract and memory Layer.
@streamsy/storage
SQLite storage for Bun and Durable Objects.
@streamsy/projection
Checkpointed projections over one or more streams.
@streamsy/serve
HttpRouter routes, Bun and Cloudflare hosts, and action delivery.
Start locally, with explicit lifetimes.
The Hacker News demo shares one SQLite Layer across its streams and projection checkpoint, and resumes after a process restart. A Durable Object host exists, and the conformance suite exercises it on local workerd. Live deployment remains a preview pending a hosted evidence run. Effect 4.0.5 powers the server and toolkit. Browsers use official Durable Streams client and State packages.
