Project mention: Show HN: BoGO – Generate Go back end services directly from SQL files | news.ycombinator.com | 2025-10-17
Very cool, reminds me of both [sqlc](https://sqlc.dev) and [oapi-codegen](https://github.com/oapi-codegen/oapi-codegen)
I'm not a fan of the enterprisey hexagonal-style code this generates, but I can understand where this might be useful for someone who does follow that.
A question regarding evolution: it's rare that schemas stay constant. I'm not sure if this tool will lend itself well when the time comes to, say, add another table, though I might be misunderstanding here.
