Seed is a Rust front-end framework for creating fast and reliable web apps with an Elm-like architecture.

• completely written in Rust, including the templating system (e.g. div! macro).
• built-in state management that is based on the Elm architecture.
• clear and extensive documentation for Rust beginners and pros alike.
• WebAssembly.

Why Seed?

Seed allows you to develop the front-end with all the benefits of Rust, meaning speed, safety, and too many more things to count.

The Seed templating system uses a macro syntax that makes Rustaceans feel right at home. This means linting, formatting, and commenting will work, and it's all in Rust. This is opposed to a JSX-like syntax that relies on IDE extensions to improve the developer experience.

Why not Seed?

• It's not maintained at the moment.
• WebAssembly is newer with less support. Browser compatibility is at 95.5%.
• Pre-built components are rare. You will likely have to roll your own components such as date pickers.
• No server-side rendering yet #232.
• You may prefer other Rust frameworks

Getting Started

To get started right away, we can use the quickstart template:

cargo install cargo-generate
cargo install trunk
cargo install wasm-bindgen-cli
cargo generate --git https://github.com/seed-rs/seed-quickstart.git --name seed-quickstart
cd seed-quickstart
trunk serve

If you get an error about wasm being linked against a different version of wasm-bindgen, just follow the suggestion to run cargo update -p wasm-bindgen. This will fix the linkings.

You should now see a working counter app in your browser at localhost:8080.

Getting into Seed

The Seed website and the library docs are the best way to learn about the functionalities of Seed.

The Seed examples are another good resource.

Trunk is the recommended application bundler for Seed. Seed projects are typically run with trunk serve instead of cargo run. You might also see cargo make start project_name in the examples. Going forward, we recommend using Trunk.

Seed Styles is a styling library for Seed to create global and scoped styles.

To use web APIs, there is web-sys which is a part of the wasm-bindgen project. wasm-bindgen is a dependency of Seed.

There are also two template repositories. However, they are not currently up to date.

• Quickstart
• Webpack quickstart

FAQ

How stable is Seed?

As a framework, Seed is mostly feature-complete. You can build complete web apps in Seed. Projects built in Seed do use Rust stable. Being in Rust, it's easy to create robust, predictable programs.
