Learn LEPTOS-RUST with Real Code Examples

Leptos provides a reactive programming model for Rust-based web applications.

Supports server-side rendering (SSR) and client-side WebAssembly execution.

Offers a component-based architecture similar to React or SolidJS.

Integrates Rust ecosystem tooling, including Cargo and crates.io libraries.

Enables type-safe, high-performance front-end development without JavaScript.

Component-based architecture with signals and effects

Reactivity system for fine-grained updates

SSR and hydration support for SEO-friendly apps

Typed event handling and property binding

Built-in support for WebSockets and async operations

Component – reusable UI building block

Signal – reactive state container

Effect – executes code when signals change

SSR – server-side rendering of HTML

Hydration – activating client-side interactivity

src/ - Rust source files for front-end and back-end

Cargo.toml - Rust project dependencies

static/ - static assets like CSS, images, JS

templates/ - optional SSR templates

build/ - compiled Wasm and server binaries

Define components using Rust functions/macros

Use signals for reactive state

Render components to HTML (SSR) or WebAssembly (client)

Bind events and data properties declaratively

Test components with Rust test frameworks or browser dev tools

Beginner: simple reactive UI component

Intermediate: SPA with routing and async data fetching

Advanced: full-stack app with SSR and client hydration

Expert: optimize WebAssembly bundle size and performance

Auditor: profiling signals and memory usage in Rust/Wasm

Leptos vs Yew: Leptos focuses on fine-grained reactivity, Yew uses virtual DOM

Leptos vs React: Leptos uses Rust + Wasm, React uses JS/TS

Leptos vs SolidJS: similar reactive patterns, but Rust-first with WebAssembly

Leptos vs Axum: Axum is back-end only; Leptos is full-stack

Leptos vs Fastly Compute@Edge: Compute@Edge runs serverless edge, Leptos is full-stack Rust framework
