Quick Overview

The stdweb crate provides a way to interact with the Web APIs from Rust code, allowing developers to build full-fledged web applications using Rust. It aims to provide a seamless integration between Rust and the browser's JavaScript environment.

Pros

  • Seamless Integration: stdweb provides a Rust-idiomatic API that closely matches the browser's Web APIs, making it easy for Rust developers to work with the web platform.
  • Cross-Compilation: Rust's cross-compilation capabilities allow stdweb to be used to build web applications that can run on a variety of platforms and devices.
  • Performance: Rust's focus on performance and safety translates to efficient web applications built with stdweb.
  • Ecosystem Integration: stdweb integrates well with other Rust crates, allowing developers to leverage the broader Rust ecosystem for their web development needs.

Cons

  • Browser Support: While stdweb supports a wide range of browsers, it may not work with all browsers or browser versions, especially older ones.
  • Dependency Management: The stdweb crate has a relatively large number of dependencies, which can make dependency management more complex.
  • Learning Curve: Developers new to Rust may face a steeper learning curve when working with stdweb, as they need to understand both Rust and the web platform.
  • Maturity: Compared to more established web development frameworks and libraries, stdweb is a relatively young project, which may mean fewer resources and community support.

Code Examples

Rendering a Simple HTML Element

use stdweb::web::document;
use stdweb::web::html_element::DivElement;

fn main() {
    stdweb::initialize();
    let div: DivElement = document().create_element("div").unwrap().try_into().unwrap();
    div.set_inner_html("Hello, World!");
    document().body().append_child(&div);
    stdweb::event_loop();
}

This code creates a new div element, sets its inner HTML to "Hello, World!", and appends it to the document's body.

Handling User Interactions

use stdweb::web::document;
use stdweb::web::html_element::ButtonElement;
use stdweb::web::event::ClickEvent;

fn main() {
    stdweb::initialize();
    let button: ButtonElement = document().create_element("button").unwrap().try_into().unwrap();
    button.set_inner_html("Click me!");

    let onclick_callback = |_: ClickEvent| {
        js! { alert("You clicked the button!"); }
    };

    button.add_event_listener(onclick_callback);
    document().body().append_child(&button);
    stdweb::event_loop();
}

This code creates a button element, sets its inner HTML, and adds a click event listener that displays an alert when the button is clicked.

Interacting with the Browser's Web APIs

use stdweb::web::{document, IParentNode, IWindowObject};
use stdweb::web::window;

fn main() {
    stdweb::initialize();
    let title = document().title();
    println!("The current page title is: {}", title);

    let width = window().inner_width();
    let height = window().inner_height();
    println!("The current window size is: {}x{}", width, height);

    stdweb::event_loop();
}

This code retrieves the current page title and the size of the browser window, and prints the information to the console.

Getting Started

To get started with stdweb, you'll need to have Rust installed on your system. You can then add the stdweb crate to your Cargo.toml file:

[dependencies]
stdweb = "0.4.20"

Next, you can start writing your web application using the stdweb APIs. Here's a simple example that creates a button and displays an alert when it's clicked:

use stdweb::web::document;
use stdweb::web::

Competitor Comparisons

wasm-bindgen logo

wasm-bindgen

8,355

Facilitating high-level interactions between Wasm modules and JavaScript

Pros of wasm-bindgen

  • More actively maintained and widely adopted in the Rust ecosystem
  • Offers better integration with JavaScript tooling and bundlers
  • Supports a wider range of JavaScript types and features

Cons of wasm-bindgen

  • Steeper learning curve for beginners
  • Requires more boilerplate code for simple use cases
  • Can be more verbose for certain tasks

Code Comparison

stdweb:

#[macro_use]
extern crate stdweb;
use stdweb::web::Window;

fn main() {
    stdweb::initialize();
    let window: Window = stdweb::web::window();
    js! { console.log(@{window.location().href()}); }
}

wasm-bindgen:

use wasm_bindgen::prelude::*;

#[wasm_bindgen]
extern "C" {
    #[wasm_bindgen(js_namespace = console)]
    fn log(s: &str);
}

#[wasm_bindgen(start)]
pub fn main() {
    log("Hello from Rust!");
}

Summary

While stdweb provides a simpler API for basic Web interop, wasm-bindgen offers more comprehensive JavaScript integration and is better suited for complex projects. stdweb's syntax may be more intuitive for some developers, but wasm-bindgen's approach aligns more closely with the direction of the Rust and WebAssembly ecosystem.

yewstack logo

yew

31,806

Rust / Wasm framework for creating reliable and efficient web applications

Pros of Yew

  • More active development and larger community support
  • Better performance due to its virtual DOM implementation
  • Comprehensive documentation and examples

Cons of Yew

  • Steeper learning curve for developers new to Rust and web development
  • Larger bundle sizes compared to simpler alternatives

Code Comparison

Yew:

use yew::prelude::*;

#[function_component(App)]
fn app() -> Html {
    html! { <h1>{"Hello, World!"}</h1> }
}

stdweb:

use stdweb::web::document;
use stdweb::unstable::TryInto;

fn main() {
    let body: web::Element = document().body().unwrap();
    body.append_html("<h1>Hello, World!</h1>");
}

Summary

Yew is a more modern and feature-rich framework for building client-side web applications in Rust. It offers better performance and a more active ecosystem compared to stdweb. However, it may have a steeper learning curve and result in larger bundle sizes.

stdweb, on the other hand, provides a simpler approach to web development in Rust, with a more straightforward API. It may be easier for beginners to grasp but lacks some of the advanced features and optimizations found in Yew.

The choice between the two depends on the project requirements, developer experience, and desired level of control over the application's structure and performance.

seed-rs logo

seed

3,842

A Rust framework for creating web apps

Pros of Seed

  • More actively maintained with regular updates
  • Focuses on a complete frontend framework, offering a more opinionated structure
  • Better documentation and examples for getting started

Cons of Seed

  • Steeper learning curve for developers new to Rust web development
  • Less flexibility compared to the lower-level approach of stdweb
  • Potentially larger bundle sizes due to included framework features

Code Comparison

Seed example:

#[derive(Default)]
struct Model {
    count: i32,
}

fn update(msg: Msg, model: &mut Model, _: &mut impl Orders<Msg>) {
    match msg {
        Msg::Increment => model.count += 1,
    }
}

stdweb example:

#[derive(Clone, Debug)]
struct Model {
    count: i32,
}

fn update(model: &mut Model, msg: Msg) {
    match msg {
        Msg::Increment => model.count += 1,
    }
}

Summary

Seed provides a more comprehensive framework for building web applications in Rust, offering better documentation and a more structured approach. However, it may be less flexible and have a steeper learning curve compared to stdweb. stdweb, on the other hand, offers a lower-level interface to web APIs, providing more flexibility but requiring more manual setup and configuration.

gloo

1,889

A modular toolkit for building fast, reliable Web applications and libraries with Rust and WASM

Pros of gloo

  • More actively maintained with regular updates
  • Better integration with the official wasm-bindgen ecosystem
  • Broader scope, covering more Web APIs and features

Cons of gloo

  • Steeper learning curve due to its more comprehensive nature
  • May have more dependencies, potentially increasing bundle size
  • Less opinionated, requiring more decision-making from developers

Code Comparison

stdweb:

#[macro_use]
extern crate stdweb;
use stdweb::web::*;

fn main() {
    stdweb::initialize();
    let button = document().query_selector("#myButton").unwrap();
    button.add_event_listener(|_: ClickEvent| {
        js! { console.log("Button clicked!"); }
    });
    stdweb::event_loop();
}

gloo:

use gloo_events::EventListener;
use wasm_bindgen::prelude::*;
use web_sys::{console, window, Element};

#[wasm_bindgen(start)]
pub fn main() {
    let window = window().unwrap();
    let document = window.document().unwrap();
    let button: Element = document.query_selector("#myButton").unwrap().unwrap();
    EventListener::new(&button, "click", move |_event| {
        console::log_1(&"Button clicked!".into());
    }).forget();
}

📦✨ your favorite rust -> wasm workflow tool!

Pros of wasm-pack

  • Officially supported by the Rust and WebAssembly Working Group
  • Provides a complete toolchain for building, testing, and publishing Rust-generated WebAssembly
  • Integrates well with npm and JavaScript ecosystems

Cons of wasm-pack

  • Steeper learning curve for developers new to Rust and WebAssembly
  • May require additional configuration for complex projects
  • Less flexible for custom WebAssembly setups compared to stdweb

Code Comparison

stdweb:

#[macro_use]
extern crate stdweb;

use stdweb::web::Window;

fn main() {
    stdweb::initialize();
    let window: Window = stdweb::web::window();
    js! { console.log("Hello from stdweb!"); }
}

wasm-pack:

use wasm_bindgen::prelude::*;

#[wasm_bindgen]
pub fn greet() {
    web_sys::console::log_1(&"Hello from wasm-pack!".into());
}

The stdweb example uses a macro-based approach for JavaScript interop, while wasm-pack relies on wasm-bindgen and web-sys for more idiomatic Rust code. wasm-pack's approach is generally considered more maintainable and type-safe, but may require more setup initially.

Patrons

This software was brought to you thanks to these wonderful people:

  • Embark Studios
  • Joe Narvaez
  • Eduard Knyshov
  • Anselm Eickhoff
  • Johan Andersson
  • Stephen Sugden
  • is8ac

Thank you!

Examples

You can directly embed JavaScript code into Rust:

let message = "Hello, 世界!";
let result = js! {
    alert( @{message} );
    return 2 + 2 * 2;
};

println!( "2 + 2 * 2 = {:?}", result );

Closures are also supported:

let print_hello = |name: String| {
    println!( "Hello, {}!", name );
};

js! {
    var print_hello = @{print_hello};
    print_hello( "Bob" );
    print_hello.drop(); // Necessary to clean up the closure on Rust's side.
}

You can also pass arbitrary structures thanks to serde:

#[derive(Serialize)]
struct Person {
    name: String,
    age: i32
}

js_serializable!( Person );

js! {
    var person = @{person};
    console.log( person.name + " is " + person.age + " years old." );
};

This crate also exposes a number of Web APIs, for example:

let button = document().query_selector( "#hide-button" ).unwrap().unwrap();
button.add_event_listener( move |_: ClickEvent| {
    for anchor in document().query_selector_all( "#main a" ) {
        js!( @{anchor}.style = "display: none;"; );
    }
});

Exposing Rust functions to JavaScript is supported too:

#[js_export]
fn hash( string: String ) -> String {
    let mut hasher = Sha1::new();
    hasher.update( string.as_bytes() );
    hasher.digest().to_string()
}

Then you can do this from Node.js:

var hasher = require( "hasher.js" ); // Where `hasher.js` is generated from Rust code.
console.log( hasher.hash( "Hello world!" ) );

Or you can take the same .js file and use it in a web browser:

<script src="hasher.js"></script>
<script>
    Rust.hasher.then( function( hasher ) {
        console.log( hasher.hash( "Hello world!" ) );
    });
</script>

If you're using Parcel you can also use our experimental Parcel plugin; first do this in your existing Parcel project:

$ npm install --save parcel-plugin-cargo-web

And then simply:

import hasher from "./hasher/Cargo.toml";
console.log( hasher.hash( "Hello world!" ) );

Design goals

  • Expose a full suite of Web APIs as exposed by web browsers.
  • Try to follow the original JavaScript conventions and structure as much as possible, except in cases where doing otherwise results in a clearly superior design.
  • Be a building block from which higher level frameworks and libraries can be built.
  • Make it convenient and easy to embed JavaScript code directly into Rust and to marshal data between the two.
  • Integrate with the wider Rust ecosystem, e.g. support marshaling of structs which implement serde's Serializable.
  • Put Rust in the driver's seat where a non-trivial Web application can be written without touching JavaScript at all.
  • Allow Rust to take part in the upcoming WebAssembly (re)volution.
  • Make it possible to trivially create standalone libraries which are easily callable from JavaScript.

Getting started

Take a look at some of the examples:

  • examples/minimal - a totally minimal example which calls alert
  • examples/todomvc - a naively implemented TodoMVC application; shows how to call into the DOM
  • examples/hasher - shows how to export Rust functions to JavaScript and how to call them from a vanilla web browser environment or from Nodejs
  • examples/hasher-parcel - shows how to import and call exported Rust functions in a Parcel project
  • pinky-web - an NES emulator; you can play with the precompiled version here

The API documentation is also available for you to look at.

Running the examples

  1. Install cargo-web:

    $ cargo install -f cargo-web

  2. Go into examples/todomvc and start the example using one of these commands:

    • Compile to WebAssembly using Rust's native WebAssembly backend:

      $ cargo web start --target=wasm32-unknown-unknown

    • Compile to asm.js using Emscripten:

      $ cargo web start --target=asmjs-unknown-emscripten

    • Compile to WebAssembly using Emscripten:

      $ cargo web start --target=wasm32-unknown-emscripten

  3. Visit http://localhost:8000 with your browser.

For the *-emscripten targets cargo-web is not necessary, however the native wasm32-unknown-unknown which doesn't need Emscripten requires cargo-web to work!
