Database for Kemal server in Crystal lang
imdrasil/jennifer.cr is my ORM of choice, but I'm no longer following the recommended config directory in the root of the project. I'm just stuffing initializers to be required from the main app files (i.e. src/app.cr).

Have you checked out Crystal?
For a more concrete example, I don't think you can have ActiveRecord-like classes which have their fields defined by fetching actual database schema (without defining the schema upfront, like Jennifer does).

Announcing Didact the anti-CMS!
This project has been half a year in the making. I've learned so much from it, most importantly Crystal and learning to love SQLite and hate Postgres. The journey led me through contributing to several dependencies, including the Granite ORM, Markd, the SQLite3 bindings, and even creating Sanemark implementing it in a fork of Markd!

It seems like Rust software is bad
The 3 Crystal ORMs I've checked out, Granite, Clear, and Jennifer, are all 10k lines or less. Given Crystal's pragmatism-before-purity philosophy compared to Rust, I'd expect them to be a little briefer, but not that much.

Frustrations with Crystal ORMs
The "generate create table SQL from model definition" feature is not usable for my use case because it doesn't treat foreign keys at all, only basic fields and types. It actually doesn't even support NOT NULL columns right now except for the primary key, and my PR to fix that has been hanging for two weeks.
What are some alternatives?
When comparing jennifer and granite-orm you can also consider the following projects:
crecto - Database wrapper and ORM for Crystal, inspired by Ecto
avram - A Crystal database wrapper for reading, writing, and migrating Postgres databases.
active_record.cr - Active Record pattern implementation for Crystal.
clear - Advanced ORM between postgreSQL and Crystal
ohm-crystal - Ohm for Crystal
stal-crystal - Set algebra solver for Redis
core - A delightful SQL ORM ☺️
