Hello,
In
var session=basex.Session(host, port, username, password)
is basex.Session a synchronous function? Can it be assumed that the session was created successfully if no socketError event is emitted?
Thanks.

The Session function only starts the connection process by calling net.createConnection. The rest is asynchronous. Each Session has a state

var states = {
    DISCONNECTED: 0,
    CONNECTING: 1,
    AUTHORIZE: 2,
    CONNECTED: 3,
    CLOSING: 4
};

Immediately after a session object is created with no error it is in state CONNECTING

The `Session` function only starts the connection process by calling [net.createConnection](https://nodejs.org/api/net.html#net_net_createconnection_port_host_connectlistener).

Thank you. Is there a way then that my application can be informed when the connection has been made successfully?

The session will emit a "connect" event https://github.com/apb2006/basex-node/blob/master/index.js#L127
