## What it is
A Ruby gem providing declarative helpers (expose, expose!, exposure_config) for Rails controllers to lazily expose models and memoized attributes. It reduces boilerplate in CRUD controllers by automatically finding or building records from params.

## Use cases
- reduce boilerplate in Rails CRUD controllers
- declaratively expose models to controller actions and views
- memoize controller instance variables lazily
- customize how records are fetched or built per controller
- clean up controller code in a Rails monolith

## When to choose
- you maintain a Ruby on Rails app with repetitive controller code
- you want a small, focused DSL for controller exposures
- you prefer declarative controller patterns over manual find/new logic

## When to avoid
- you don't use Ruby on Rails
- you prefer explicit controller code without metaprogramming magic
- you need a library with frequent recent releases

## Facets
- artifact type: library
- maturity: maintenance
- function: middleware, web-framework
- domain: web-development, backend, developer-tools
- platform: ruby
- tags: rails, controllers, gem, crud, declarative, web-server
