It's not working for me, i want to make an app that'll send an sms with my steamguard code when i try to log in exactly like steam mobile app. 

I tried it like this:
 

client.on('steamGuard', function (domain, callback, lastCodeWrong) {
    if(!domain)console.log("We need a 2fa code bro");
    if (lastCodeWrong)console.log("Last code was wrong");
    console.log("Steam Guard code needed from email ending in " + domain);
});

but when i try to log in by steam desktop client nothing happens

That is currently not possible.

So how SteamMobileApp done it?

They use some form of push notifications that haven't been reverse-engineered yet, and likely never will. Probably Firebase.
