Yew is a framework for building front-end web applications using Rust and WebAssembly. It provides a component-based architecture that allows developers to create modular, reusable user interface elements that manage their own state and logic. By compiling code into binary modules, the framework enables high-performance execution within modern browser environments.
The framework distinguishes itself through a macro-based markup language that transforms declarative, HTML-like syntax into strongly-typed component structures during compilation. It features a robust server-side rendering engine that generates initial HTML to improve page load performance and search engine visibility. This is complemented by a hydration-capable runtime that synchronizes state and event listeners between server-generated markup and the client-side application, ensuring a transition to full interactivity without requiring a full page re-render.
Yew supports complex interface development through virtual DOM reconciliation, which applies minimal updates to the browser document based on state changes. It also incorporates suspense-driven data fetching to manage asynchronous operations, ensuring that components only render once their required data is resolved. The framework includes tools for bundling web applications and configuring build environments to target WebAssembly platforms.
