## What it is
StimulusReflex is a Ruby gem and JavaScript client that lets Rails developers build reactive, real-time applications by rendering HTML on the server and delivering updates over WebSockets via ActionCable. It extends Stimulus controllers with reflexes that re-render ERB templates and morph the DOM, avoiding the need for a separate frontend framework.

## Use cases
- build reactive real-time UIs in Rails without a JavaScript SPA framework
- update page content live over websockets from server-side Ruby
- add interactivity to server-rendered Rails apps with Stimulus
- replace React/Vue with server-rendered HTML updates in a Rails monolith
- stream DOM morphs to clients using ActionCable and CableReady

## When to choose
- you have a Rails app with ERB templates and want reactive UI without a full frontend stack
- your team is Ruby-focused and wants real-time features with familiar tooling
- you want fast server-rendered HTML updates over websockets

## When to avoid
- you need a rich client-side state model or offline-first SPA behavior
- your stack is not Ruby on Rails
- you prefer JSON APIs with a dedicated frontend framework
