sup guys, i have one problem:

async function isInstalled(clientName: string): Promise<boolean> {
    return await invoke("is_installed", { client: clientName });
}

(async() => {
    console.log(await isInstalled("fold_name"));
})(); // prints false

function isInstalled() {
  const [installed, setInstalled] = useState<boolean | null>(null);

  useEffect(() => {
    const checkInstallation = async () => {
      console.log("i'am here");
      const result = await isInstalled("fold_name");
      setInstalled(result);
      console.log("result:", result);
    };
  
    checkInstallation();
  }, []);
  
  return (
    <>
      <p>{installed ? "yep" : "no"}</p>
    <>
  )
} // prints only i'am here

can you share your rust command too? Also, can you log the result above the setInstalled line just to be sure that doesn't block.

main.rs

mod client;

fn main() {
  ... some tauri code
  .invoke_handler(tauri::generate_handler![client::is_installed])
}

client.rs

#[allow(unused_variables)]
#[tauri::command]
pub fn is_installed(client: &str) -> bool {
  print("#1");
  let exists =Path::new(&get_client_path(client)).exists();
  print("#2");

  exists
}

in ts:

function isInstalled() {
  const [installed, setInstalled] = useState<boolean | null>(null);

  useEffect(() => {
    const checkInstallation = async () => {
      console.log("i'am here");
      const result = await isInstalled("fold_name");
      console.log("0_o");
      setInstalled(result);
      console.log("result:", result);
    };
  
    checkInstallation();
  }, []);
  
  return (
    <>
      <p>{installed ? "yep" : "no"}</p>
    <>
  )
} // still prints only i'am here

well, only invoke is blocking the stream

[compact geyser]

alright. can you make the command async like this ```rs
#[allow(unused_variables)]
#[tauri::command]
pub async fn is_installed(client: &str) -> bool {
print("#1");
let exists =Path::new(&get_client_path(client)).exists();
print("#2");

exists
}

On that note, does #1 / #2 print?

If that also doesn't help, i'm afraid i also need the get_client_path code

[blazing grove]

no, #1 and #2 don't print

fn get_client_path(client: &str) -> String {
  format!("{}\\{client}", *CLIENT_FOLDER)
}

get_client_path just concatenate strings

and about make is_installed function async:

#[tauri::command] -> `__tauri_message__` does not live long enough
borrowed value does not live long enough

[compact geyser]

oh right

does client: String instead of client: &str work?

[blazing grove]

yep

wait a minute, i'll test it

no, it doesn't work

[compact geyser]

what about the terminal where you run tauri dev do the numbers get printed?

[blazing grove]

no

[compact geyser]

that's so weird

[blazing grove]

well, yep

[blazing grove]

any ideas?

[compact geyser]

Is your repo public?

Or can you create a minimal reproduction for me to try?

I don't see anything wrong in your screenshots...

[blazing grove]

well, seems like i found answer to this shit, probably invoke doesn't working because i'am using it in iframe

yep, its it

its weird, but invoke doesn't work in iframe

although I can guess why.
