More #eventsourcing #ruby progress: this is using SQLite for the event store backend, and a "vibe-coded" 😳 Unix socket contraption for real-time pub/sub

Holy shit it looks like I got my Ruby event-sourcing library working with SQLite. This is promising!

And a (simulated) payment workflow that runs concurrently from order fulfilment

Why does the FulfillOrder command handler also check whether all items are fulfilled? Because that might have changed in the meantime. Eventual consistency is fun!

Many ways to do this, but the Order actor reacts to its own "ItemFulfilled" events, and if all line items have been fulfilled, then it schedules a command to fulfil itself.

I'm also extracting some common patterns into a library. Such as turning command structs into auto-validating forms, and eventually all the machinery for reactive UIs.
