The earlier section reveals how Express expects route capabilities to return errors. The framework is designed to be used with asynchronous capabilities that take a callback function (with an error and result argument), which is identified as when the operation completes. The code under reveals how this works, utilizing the instance of a database question that takes a callback function, and returns both an error err or some results. If err is returned, next known as with err as the value in its first parameter (eventually the error propagates to our global error handling code). On success the desired data is returned after which used in the response. The “about” route (reproduced below) is defined utilizing the Router.get() method, which responds solely to HTTP GET requests.
