2. Modify lib.rs to initialize the plugin:

   src-tauri/src/lib.rs

   #[cfg_attr(mobile, tauri::mobile_entry_point)]
   pub fn run() {
       tauri::Builder::default()
           .plugin(tauri_plugin_localhost::Builder::new().build())
           .run(tauri::generate_context!())
           .expect("error while running tauri application");
   }

Usage

The localhost plugin is available in Rust.

src-tauri/src/lib.rs

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()?;
          Ok(())
      })
      .run(tauri::generate_context!())
      .expect("error while running tauri application");
}
