Lib.rs

Cross-platform WebView rendering library in Rust that supports all major desktop platforms like Windows, macOS, and Linux.

Overview

Wry connects the web engine on each platform and provides easy to use and unified interface to render WebView. It also re-exports tao as a module for event loop and window creation.

Usage

The minimum example to create a Window and browse a website looks like following:

fn main() -> wry::Result<()> {
  use wry::{
    application::{
      event::{Event, StartCause, WindowEvent},
      event_loop::{ControlFlow, EventLoop},
      window::WindowBuilder,
    },
    webview::WebViewBuilder,
  };

  let event_loop = EventLoop::new();
  let window = WindowBuilder::new()
    .with_title("Hello World")
    .build(&event_loop)?;
  let _webview = WebViewBuilder::new(window)?
    .with_url("https://tauri.studio")?
    .build()?;

  event_loop.run(move |event, _, control_flow| {
    *control_flow = ControlFlow::Wait;

    match event {
      Event::NewEvents(StartCause::Init) => println!("Wry has started!"),
      Event::WindowEvent {
        event: WindowEvent::CloseRequested,
        ..
      } => *control_flow = ControlFlow::Exit,
      _ => (),
    }
  });
}

There are also more samples under examples, you can enter commands like following to try them:

cargo run --example multi_window

Platform-specific notes

All platforms uses tao to build the window, and wry re-export it as application module. Here are the underlying web engine each platform uses, and some dependencies you might need to install.

Linux

Tao uses gtk-rs and its related libraries for window creation and wry also needs WebKitGTK for WebView. So please make sure following packages are installed:

Arch Linux / Manjaro:

sudo pacman -S webkit2gtk libappindicator-gtk3

Debian / Ubuntu:

sudo apt install libwebkit2gtk-4.0-dev libappindicator3-dev

Fedora

sudo dnf install gtk3-devel webkit2gtk3-devel libappindicator-gtk3-devel

macOS

WebKit is native on macOS so everything should be fine.

If you are cross-compiling for macOS using osxcross and encounter a runtime panic like Class with name WKWebViewConfiguration could not be found it's possible that WebKit.framework has not been linked correctly, to fix this set the RUSTFLAGS environment variable:

RUSTFLAGS="-l framework=WebKit" cargo build --target=x86_64-apple-darwin --release

Windows

WebView2 provided by Microsoft Edge Chromium is used. So wry supports Windows 7, 8, and 10.
