Learn SYCAMORE-RUST with Real Code Examples
Updated Nov 25, 2025
Architecture
Components defined as Rust functions or structs with reactive state
Signals hold reactive data; changes propagate automatically
View macros generate virtual DOM trees
Event handlers and reactive updates trigger fine-grained re-renders
Optional SSR and hydration for initial load and SEO
Rendering Model
View macros generate virtual DOM
Signals propagate state changes to UI
Components re-render only when reactive dependencies change
Event handlers executed in Rust
SSR generates static HTML for first load, then hydrates
