node js set timeout in ssh in ssh2

Question

How can I set a timeout for the connection to a ssh server?

Currently, I am connecting to the server with the following code:

var Client = require('ssh2');

var conn = new Client();
conn.on('ready', function(){
    console.log("connected");
});
conn.on('error', function(){
    console.log("fails");
});
conn.connect({
    host: ip,
    port: 22,
    username: user,
    password: password
});

You can set readyTimeout in the connect options like this :

conn.connect({
    host: ip,
    port: 22,
    username: user,
    password: password,
    readyTimeout: 5000
});

This will cancel any connection that is not ready within 5 seconds.

You can read more about it in the documentation of ssh2.

It does work (the default timeout is 20 seconds) however it is unclear how to handle the timeout error. It just crashes the Node app.
