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
