I’m attempting to teach myself full stack web dev using my preferred tooling (Purescript front end using Deku and Hyrule for modernized FRP, Haskell Servant back end talking to a PostgreSQL server with Nix flakes gluing at all together) by building a web app for managing cannabis dispensary inventory.

Lately, I’m finally at the point where I realize/experiment with making the app domain-agnostic. To do that, I’m attempting to extend lambdabuffers to programmatically generate my Types (and instances eventually) so I can make my whole app (front end Types, back end Types, and SQL schema) more generic in order to generate exactly the domain specific app that I currently have.

Here’s the lambdabuffer I wrote to describe my Types (for example): https://github.com/harryprayiv/cheeblr/blob/delete/backend/codegen/Inventory.lbf

And here’s my most active branch at the moment: https://github.com/harryprayiv/cheeblr/tree/delete

I also stopped working on a previous, ambitious project aimed at building a decentralized fantasy betting baseball DApp until some of the tech I’m waiting on (crypto oracles) matures enough: https://github.com/cardanonix/pelotero-engine

I welcome any and all critiques and assistance in either of these 100% FOSS projects.
