Hi use log4js module,

var log4js = require('log4js'); //include
var errorLog = {
  module: "module name",
  location: "location name",
  line: "72",
  message: err //error object
};
log4js.getLogger().error(errorLog); //writing log file

go through with the log4js documentation for more details about configuration
