How do I create a transparent frameless window in Tauri v2?

To create a transparent frameless window in Tauri v2, you must configure the window definition in tauri.conf.json by setting "decorations": false and "transparent": true, while ensuring your frontend CSS applies a transparent background with zero opacity.

{
  "app": {
    "windows": [
      {
        "label": "main",
        "decorations": false,
        "transparent": true
      }
    ]
  }
}

How do you initialize a native system tray event loop in Rust?

Initialize a native system tray in Tauri v2 inside your Rust lifecycle setup hook using TrayIconBuilder, configuring your custom event listeners with on_menu_event to match incoming action labels and execute backend code.

use tauri::tray::TrayIconBuilder;

tauri::Builder::default()
  .setup(|app| {
    let tray = TrayIconBuilder::new()
      .icon(app.default_window_icon().unwrap().clone())
      .on_menu_event(|app, event| match event.id.as_ref() {
        "quit" => std::process::exit(0),
        _ => {}
      })
      .build(app)?;
    Ok(())
  })

How to style custom window decorations with backdrop blur filters in Tailwind CSS?

To build custom window backdrops, apply Tailwind CSS backdrop-blur classes combined with dark transparency masks. You must configure matching operating system effects in Tauri, then style your outer HTML containers with blur utilities.

<!-- Styled for Mica backdrop -->
<div class="w-full h-screen rounded-xl 
  bg-slate-900/50 backdrop-blur-3xl 
  border border-white/10">
  <header class="titlebar"></header>
</div>
