# webview-bun
[bun](https://bun.sh/) bindings for [webview](https://github.com/webview/webview/)
Webview is a tiny cross-platform library to make **web-based GUIs for desktop applications**.

## Installation
Click here for instructions on 🐧 Linux
The compiled linux library in this package requires GTK 4 and WebkitGTK 6.> To use a different version, see Development section below.
- Debian-based systems: `apt install libgtk-4-1 libwebkitgtk-6.0-4`
- Arch-based systems: `yay -S gtk4 webkitgtk-6.0`
- Fedora-based systems: `dnf install gtk4 webkitgtk6.0`Click here for instructions on 🪟 Windows
The compiled windows library in this package does not bundle any webview version with itself but rather uses the system installed one.> To bundle a specific version, see Development section below.
The Microsoft Edge WebView2 runtime is required to be installed on the system for any version of Windows before Windows 11.
To manually update or install the latest version, follow the steps here.```bash
bun i webview-bun
```## Example
```typescript
import { Webview } from "webview-bun";const html = `
Hello from bun v${Bun.version} !
`;
const webview = new Webview();
webview.setHTML(html);
webview.run();
```For more examples, browse the `examples` folder of this repository.
## Single-file executable
You can compile a single self-sufficient executable file for your webview app.
For example, let's create a single executable for the above To-Do app. Clone this repository and run,
```bash
bun build --compile --minify --sourcemap ./examples/todoapp/app.ts --outfile todoapp
```
> [!TIP]
> By default, a terminal window will also open in the back when double-click opening the executable in Windows and macOS.
>
> #### 🪟 To hide it in Windows:
> Download [hidecmd.bat](https://github.com/tr1ckydev/webview-bun/blob/main/scripts/hidecmd.bat) from this repository and save in the same folder as the binary. Open terminal there and execute,
> ```bash
> .\hidecmd.bat todoapp.exe
> ```
>
> #### 🍎 To hide it in macOS:
> Add the extension `.app` in the end of the above bun build command.### Cross-platform compilation
Bun now supports cross-compilation of single executable binaries. To cross compile your webview app for a different platform run,
```bash
bun build --compile --target=bun-windows-x64 --minify --sourcemap ./examples/todoapp/app.ts --outfile todoapp
```See [full list](https://github.com/oven-sh/bun/blob/main/docs/bundler/executables.md#supported-targets) of supported `target`s.
### Bun.serve with webview
If you run a web server it will block the main thread, but using workers you can run the webview window on another thread.
[From Bun v1.1.25, you can now embed worker scripts in a standalone executable.](https://bun.sh/blog/bun-v1.1.25#worker-in-standalone-executables) Clone this repository then,
```bash
cd examples/webserver/
bun build --compile --minify --sourcemap ./index.ts ./worker.ts --outfile webserver
```> [!NOTE]
>
> On macOS, this doesn't work due to some bug in bun as webview window doesn't open from a worker.## Documentation
Refer to the comments in the source code for full documentation.
## Development
> [!IMPORTANT]
> If you are on **Windows,** you need C++ Build Tools.
>
> - Go to https://visualstudio.microsoft.com/downloads.
> - Scroll down > *All Downloads* > *Tools for Visual Studio*.
> - Download *Build Tools for Visual Studio 2022* and run.
> - Select *Desktop development with C++* and install.### Prerequisites
In addition to the dependencies mentioned during the Installation section, you need,
- `cmake`
- `ninja`
- `python3`### Building
- Clone the repository along with the [webview](https://github.com/webview/webview) submodule.
```bash
git clone --recurse-submodules https://github.com/tr1ckydev/webview-bun
cd webview-bun
bun i
```- Build the library for your platform.
> Under the hood, it invokes webview's own cmake build system to compile the shared library file.
```bash
bun run build
```
- (Optional) Clear the build cache.```bash
bun clean
```The compiled library file can be found inside the `build` folder.
### Customization
🐧 For linux, if you want to use a different WebkitGTK version, change the cmake `WEBVIEW_WEBKITGTK_API` option in *build.ts* to one of the [available values](https://github.com/webview/webview?tab=readme-ov-file#linux-specific-options).
🪟 For windows, if you want to bundle a specific webview version instead of using the system installed one, set the cmake `WEBVIEW_MSWEBVIEW2_VERSION` option to one of the [NuGet version strings](https://www.nuget.org/packages/Microsoft.Web.WebView2/#versions-body-tab).
Check out the [webview build docs](https://github.com/webview/webview?tab=readme-ov-file#customization) for more options.
### Running
> [!TIP]
> To use your own webview library, set the `WEBVIEW_PATH` environment variable with the path to your webview shared library file.Run the following example to see it in action.
```bash
bun run examples/basic.ts
```For more examples, browse the `examples` folder of this repository.
