As the title says. I want to log my users in but sometimes they get an error. For instance password too short or maybe credentials dont match.

Is there a way i can catch the error type and turn that into a variable i can use.

JavaScript


  const IsLoggedIn = async () => {
    try {
      var res = await account.get();
      if (res) {
        redirectTo("./homepage");
      }
    } catch (e) {
      setLoading(false);
    }
  };


  async function handleLogin() {
    try {
      setLoading(true);
      await account.createEmailSession(email, password);
      setPassword("");
      setLoading(false);
      IsLoggedIn();
    } catch (error) {
      console.error(error);
      setLoading(false);
    }
  }


  async function handleRegister() {
    try {
      setLoading(true);
      await account.create(ID.unique(), email, password);
      setPassword("");
      setLoading(false);
      IsLoggedIn();
    } catch (error) {
      console.error(error);


      setLoading(false);
    }
  }


  const redirectTo = (path) => {
    router.replace(path);
  };


  useEffect(() => {
    IsLoggedIn();
  }, []);

A bit off of what you've asked but instead of doing setLoading(false) in both the try and catch I believe you can utilize finally and put it there.

Kenny

If you want the specific error message you can do error as Error and then error.message to get the specific error message, and use that to display to the user.

ill try it out.

setLoading was first so i could have a spinner.

Kenny

Sure, you can do setLoading(true) outside the try catch and add a finally block to the trycatch to set loading to false.

Kenny

Maybe something like

TypeScript
setLoading(true)
try {
...something
} catch (error) {
  if(error instanceof Error) {
    setError(error.message)
  }
} finally {
  setLoading(false)
}

On AppwriteException catch (e) {
}
