webview_deno

deno bindings for webview using the webview_rust library.

Webview is a tiny cross-platform library to render web-based GUIs for desktop applications.

⚠️ This project is still in an development. Expect breaking changes.

Example

import { Webview } from "https://deno.land/x/webview/mod.ts";

const html = `
  <html>
  <body>
    <h1>Hello from deno v${Deno.version.deno}</h1>
  </body>
  </html>
`;

const webview = new Webview(
  { url: `data:text/html,${encodeURIComponent(html)}` },
);
await webview.run();

you can run this example directly from the web:

deno run -Ar --unstable https://deno.land/x/webview/examples/local.ts

or in your development environment:

deno run -Ar --unstable examples/local.ts

you can find other examples in the examples/ directory.

Development

Prerequisites

For building webview_deno the same prerequisites as for building deno is required.

A recommended dependency is denon which is used for the built in scripts found in the denon.json file.

Linux dependencies

webkit2gtk (to install using apt: sudo apt-get install libwebkit2gtk-4.0-dev)

Building

Building webview_deno can take a nontrivial amount of time depending on your operating system. After the first build most files will be cached so building time will be reduced. Building on Windows requires admin privileges.

For a default build you can use the provided script:

deno run --unstable -A scripts/build.ts

which internally runs:

optionally you can use mshtml:

deno run --unstable -A scripts/build.ts mshtml

Running

To run webview_deno without automatically downloading the binaries from releases you will need to use the environment variable PLUGIN_URL and set it to the path where the built binaries are located. This is usually file://./target/release. The process of running and using local binaries can be easier to using the dev script:

deno run --unstable -A scripts/dev.ts examples/local.ts

Environment variables

PLUGIN_URL - The URL of the plugin Due to MSHTML (internet explorer) no longer being enabled by default, the only way to enable it is to set the PLUGIN_URL variable to the path of a binary build built with the --no-default-features flag or using deno --unstable -A scripts/build.ts mshtml. This is usually ./target/release/ when developing locally.
DEBUG - Disable cache and enable logs for plug. Used for debugging.

Dependencies

Contribution

Pull request, issues and feedback are very welcome. Code style is formatted with denon fmt (which internally runs deno fmt and cargo fmt) and commit messages are done following Conventional Commits spec.
