    _client = client;
    client.session({ name: "YOURDB", username: "YOURID", password: "YOURPASSWORD" })
    .then(session => {
    // use the session
       console.log('session opened')
       _session = session;
       _handle = session.liveQuery("select from processcreate").on("data", data => {
            console.log(data);
        });
    })
});

process.stdin.resume(); //so the program will not close instantly, Ctl+C to clean-up & quit
function exitHandler(err) {
    console.log('cleaning up...')
    _handle.unsubscribe()
        _session.close()
        .then(() =>{

            _client.close()
            .then(() => {

Need to close sessions & handles, otherwise you will see lots of exceptions at server side console.
