You can find available parameters here => https://docs.docker.com/engine/api/v1.19/#get-container-logs
At least this option object will give you back incoming data

var logOpts = {
     stdout: 1,
     stderr: 1,
     tail:100,
     follow:0
};
container.logs(logOpts, function(data, err) {
    data.setEncoding('utf8');
    data.on('data', function(data) {
        for(var i in data) {
            console.log(data[i]);
        }
    })
});
