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

Frequently Asked Questions about Leptos-rust
What is Leptos-rust?
Leptos is a modern Rust framework for building full-stack web applications with reactive, fine-grained reactivity, enabling developers to write front-end and back-end code in Rust that compiles to WebAssembly for the browser.
What are the primary use cases for Leptos-rust?
Building single-page applications (SPA) with Rust. Developing full-stack Rust web apps with SSR. Creating interactive dashboards and admin panels. High-performance front-end applications without JavaScript. Porting Rust logic to browser via WebAssembly
What are the strengths of Leptos-rust?
Write front-end and back-end in one language (Rust). High-performance WebAssembly execution. Type safety reduces runtime errors. Reactive updates without virtual DOM overhead. Strong integration with Rust tooling and crates
What are the limitations of Leptos-rust?
Smaller ecosystem compared to JavaScript frameworks. Learning curve for Rust and WebAssembly newcomers. SSR setup can be complex for beginners. Debugging WebAssembly code is less mature than JS debugging. Limited third-party UI libraries compared to JS
