How to use the tiny-lr.changed function in tiny-lr

em.on(evt, function(file) {

                console.log(getCurT() + " Send-Changed: " + color(file,"cyan"));
                // send msg of changed file info
                // sendMsg(file || "index.html");
                tinyLr.changed(file || "index.html");//It is not 'server.changed({ params: { files: files }})'
            });
        });
