Symfony UX

Need frontend interactivity?
|
+-- Pure JavaScript behavior (no server)?
|   -> Stimulus
|      (DOM manipulation, event handling, third-party libs)
|
+-- Navigation / partial page updates?
|   -> Turbo
|      +-- Full page AJAX        -> Turbo Drive (automatic, zero config)
|      +-- Single section update  -> Turbo Frame
|      +-- Multiple sections      -> Turbo Stream
|
+-- Reusable UI component?
|   |
|   +-- Static (no live updates)?
|   |   -> TwigComponent
|   |      (props, blocks, computed properties)
|   |
|   +-- Dynamic (re-renders on interaction)?
|       -> LiveComponent
|          (data binding, actions, forms, real-time validation)
|
+-- Need icons?
|   -> UX Icons
|      (inline SVG from 200+ Iconify sets or local files)
|
+-- Need an interactive map?
|   -> UX Map
|      (Leaflet or Google Maps, markers, polygons, circles)
|
+-- Real-time (WebSocket/SSE)?
    -> Turbo Stream + Mercure
