use tauri::{webview::WebviewWindowBuilder, WebviewUrl};

pub fn run() {
  let port: u16 = 9527;

  tauri::Builder::default()
      .plugin(tauri_plugin_localhost::Builder::new(port).build())
      .setup(move |app| {
          let url = format!("http://localhost:{}", port).parse().unwrap();
          WebviewWindowBuilder::new(app, "main".to_string(), WebviewUrl::External(url))
              .title("Localhost Example")
              .build()?;
