JavaScript Convert node.js HTTP response function (using “request” library) to use streams nodejs convert http to https

I'm using the request library in node.js, which downloads an HTML body response, but does so in chunks. Currently I'm just concatenating them into a dataChunks variable and using a hacked-together test to see when it's all downloaded. However, I've skim-read the Stream Handbook, and this seems like a case where it might be appropriate to use a stream to get the data chunks. I don't fully understand how I'd do this though, so would appreciate any help. The relevant code is below:

var dataChunks = "";

request.get({ url: baseUrl + path })
            .on("error", function(err) { throw new Error(err); })
            .on("response", function(res) {
                if (res.statusCode === 200) {
                    res.on("data", function(data) {
                        var dataString, dt;

                        dataChunks += (dataString = data.toString());

                        if ((dt = dataString.slice(-100).trimRight()).lastIndexOf("</html>") === dt.length - 7) {
                            // do stuff with dataChunks
                        }
                    });
                }
            });

Thank you in advance for any help.
