Turbo (Rails/Hotwire)

Developer Tools

Server-side rendering acceleration framework for Rails — makes multi-page Rails apps feel like SPAs without writing JavaScript. Turbo has three parts: Turbo Drive (intercepts link clicks/form submits, replaces <body> via AJAX — no full page reload), Turbo Frames (<turbo-frame id='agents'> loads frame content independently), and Turbo Streams (server-side HTML fragments pushed via WebSocket or SSE to update specific page elements). Server broadcasts: Turbo::StreamsChannel broadcasts DOM updates from ActiveRecord callbacks. <%= turbo_stream.append 'agents', @agent %> appends new agent to list in real-time. Core of Rails 7+ Hotwire stack. Works with Action Cable for real-time agent updates.
