Learn SEED-RUST with Real Code Examples

Seed leverages Rust’s strong type system to build reliable and safe web apps.

It compiles Rust code to WebAssembly for high-performance execution in browsers.

Uses a virtual DOM and reactive message-driven architecture for UI updates.

Supports modular components and easy state management.

Integrates with JavaScript, Web APIs, and standard Rust crates via wasm-bindgen.

Model-Update-View pattern for state management

HTML macro for defining UI declaratively

Async tasks and HTTP requests support

Modular component system

Integration with standard Rust crates and JS libraries

Model - app state

Msg - messages representing user events or actions

Update - function to update Model based on Msg

View - function mapping Model to HTML/DOM

Component - reusable UI building block

Cargo.toml - Rust dependencies and project metadata

src/lib.rs or main.rs - main app logic

index.html - HTML entry point for Wasm app

static/ - static assets like CSS and images

components/ - optional folder for reusable Seed components

Define Model and Msg enums

Implement update function for state changes

Define view function with HTML macro

Optionally create reusable components

Build with Trunk and test in browser

Beginner: simple counter app

Intermediate: form handling and validation

Advanced: SPA with routing and async tasks

Expert: interactive dashboard with external API integration

Architect: large-scale web app with reusable components and state management

Seed vs Yew: simpler, lighter-weight vs larger ecosystem

Seed vs React: Rust+Wasm vs JS ecosystem

Seed vs Elm: similar architecture, Rust vs Elm language

Seed vs Svelte: reactive UI, Rust vs JS

Seed vs Vue: component-based vs Rust safety and performance
