If the code below isn't displaying the short description of the status code.


Then in the top of the document, add a new variable called http that requires "http".

var http = require("http");

You didn't say what your issue is, but perhaps it is due to your second code fragment.

:point_right: Here's a corrected version of that code fragment:

var http = require("http");  // not "requires"

In the video, we're trying to display the status description. As of September 2016, the solution shown on the video doesn't work anymore.

The old way to view the status description, shown in the video is this:


And now it should just look like this:


as it's the proper way to achieve what we're trying to in the video, with the newest version of Node.

Since we are now using "https" to get into treehouse's profile, removing the http.RESPONSE_CODES corrected the very long console error printout I was seeing when I used a wrong version of my username.

      printError({message :"There was an error getting the profile for " + username + ". (" + http.
STATUS_CODES[response.statusCode] + ")"});                                                         

ReferenceError: http is not defined                                                                
    at IncomingMessage.<anonymous> (/home/treehouse/workspace/app.js:36:95)                        
    at emitNone (events.js:91:20)                                                                  
    at IncomingMessage.emit (events.js:185:7)                                                      
    at endReadableNT (_stream_readable.js:934:12)                                                  
    at _combinedTickCallback (internal/process/next_tick.js:74:11)                                 
    at process._tickCallback (internal/process/next_tick.js:98:9)   

I think it is because there is no http.RESPONSE_CODES in node.js documentation for using https. Hope this helps. The bottom code made me print out the shorter version of the error with status code.

printError({message :"There was an error getting the profile for " + username + ". (" + response.statusCode + ")"})

^^^ Much thanks to Patryk for solving this issue (for me too), but I used response.statusCode (not response.statusMessage) and it worked. Is there a difference?

Why can't we use response.statusText in Node.js?
