Learn LEPTOS-RUST with Real Code Examples
Updated Nov 25, 2025
Architecture
Components manage reactive signals for state
Server renders initial HTML via SSR
Client hydrates with WebAssembly for interactivity
Reactive system updates DOM efficiently on state changes
Supports routing, server communication, and async tasks
Rendering Model
Define component -> render HTML (SSR) -> send to client
Client loads WebAssembly -> hydrates SSR HTML
Signals manage reactive state updates
Effects trigger UI changes based on state
DOM updates are fine-grained and efficient
