My 5c about this, as always somewhat heretical. "Bounded context" is vague and not really interesting/useful. Vertical slice architecture is not an architecture, but a principle *within* an architecture. In particular, in the Onion architecture (my default). #DDD 🔽

Only if you are making a fat client and the back-end is merely a thin layer between it and the DB and other infra.

I wrote about using GADTs in a design for #eventsourcing API in a #haskell back-end. Somewhat related to the recent post by @mattoflambda.bsky.social systema10.org/posts/making...

Working on refining my #eventsourcing design/template for #haskell applications. Using GADTs we can turn on or off optimistic concurrency check using "global" journal versions. Depending on the on/off setting, the "concurrent change detected" outcome becomes impossible and need not be handled.

Streams per entity are fundamentally in conflict with the basic essence of #eventsourcing. The essence being that we can compute *anything* by folding all records. Counter-example: find all customers in a system where each customer has a dedicated journal/stream by customer ID.

Is the cabal 'data-files' machinery useful for static files needed by a Haskell Web application, for example CSS, JS and similar? What are best practices for "packaging" together the latter and the build product of cabal? A build system on top of cabal? #haskell

Beyond basic programs, HM-like type systems can be quite mysterious and awesome. The definitions and types of the #purescript functions below look strange at the first sight. I wonder how IWSAMs will fare when ported to #fsharp.
