## What it is
A collection of composable mixin behaviors for Stimulus controllers in Hotwire/Rails apps. It adds standard lifecycle behaviors like intersection, resize, and click-outside observers via tree-shakeable ES6 modules with TypeScript types.

## Use cases
- run callbacks when an element appears or disappears in the viewport
- detect clicks outside an element to close dropdowns or modals
- react to element resizing in a Stimulus controller
- add reusable behaviors to Hotwire Turbo apps
- compose multiple observer behaviors into one Stimulus controller

## When to choose
- you use Stimulus or Hotwire and want standard controller behaviors without writing boilerplate
- you want small, tree-shakeable, typed mixins
- you need observer-based interactions like click-outside, intersection, or resize

## When to avoid
- your frontend does not use Stimulus or Hotwire
- you need a full component framework rather than controller mixins

## Facets
- artifact type: library
- maturity: active
- function: ui-components, middleware, developer-tools
- domain: frontend, web-development
- platform: browser, cross-platform
- tags: stimulus, hotwire, turbo, mixins, typescript, observers, composable-behaviors, nodejs
