Regarding this, how do you handle errors in node JS?

You should also be familiar with the four main ways to deliver an error in Node. js: throw the error (making it an exception). pass the error to a callback, a function provided specifically for handling errors and the results of asynchronous operations.

Likewise, what is an Epipe error? EPIPE means that writing of (presumably) the HTTP request failed. because the other end closed the connection.

Simply so, what is a callback error?

The first argument of the callback is usually named error, whereby if something goes wrong in the asynchronous function, then the callback gets called with the first argument which specifies what error has happened. If everything goes well, then the first argument will be null.
