Learn YEW with Real Code Examples

Yew allows developers to write web frontends in Rust, compiling to WebAssembly for high-performance execution in browsers.

It supports a component-based model with properties, messages, and lifecycle hooks.

Includes a virtual DOM for efficient UI updates and re-rendering.

Integrates with web APIs such as fetch, WebSockets, and local storage.

Ideal for building fast, type-safe web applications without relying on JavaScript.

HTML-like macro syntax for building UI (`html!`) in Rust

Message-based component communication

Properties (props) for component configuration

Lifecycle hooks (create, update, change, destroy)

Integration with browser APIs and JS interop

Component - reusable UI unit

Message - triggers updates inside components

Props - component input properties

Virtual DOM - efficient UI rendering

Lifecycle hooks - component creation, update, and destruction

src/ - main Rust source code

Cargo.toml - project dependencies and metadata

index.html - root HTML page

static/ - static assets (images, CSS)

tests/ - unit and integration tests

Write Rust code using `html!` macro for UI

Define components with messages and props

Use message passing to handle events and state updates

Build project to WebAssembly using `trunk` or `wasm-pack`

Serve app via local server and test in browser

Beginner: simple interactive component

Intermediate: SPA with routing and state management

Advanced: complex dashboard with async data fetching

Expert: WebAssembly game or graphics-heavy app

Auditor: optimize performance and memory usage in Wasm

Yew vs React: Rust/Wasm vs JavaScript, stronger type safety and performance

Yew vs Svelte: Component-based UI, but compiled to Wasm vs JS

Yew vs Angular: Yew is Rust-focused, Angular is full-featured JS framework

Yew vs Seed: Both Rust/Wasm frameworks, Yew has larger ecosystem

Yew vs Vanilla JS: Type-safe Rust with virtual DOM vs JS direct DOM manipulation

2018 – Yew initial release

2022–2025 – Performance improvements, new macros, larger community adoption

Component - reusable UI element

Message - triggers state update

Props - input parameters to components

Virtual DOM - optimized UI diffing

Wasm - WebAssembly compiled output from Rust
