I am getting an unhandled error event after viewing the webpage

After I run the app.js file, I view the webpage. I come back and in the console, I get this error message: Server running at port: 3000
events.js:160
throw er; // Unhandled 'error' event

Error: write after end

To spare some people with a similar problem some time of frustration: One possibility , apart from the obvious .end in the wrong place, is that you set the if(username.length > 0)-statement of the user-function in the router.js file to if(username.length >= 0)

For an error message this one is fairly straight-forward, "Error: write after end". Once you call response.end() you can write to it anymore because the response is supposed to be closed out after that. Calling response.write() after that causes the error.

You can post your code if you still need help finding the problem.
