Completing the MAKE IT MODULAR exercise with a correct output still results in a failure. The failure is caused both by this code as well as the answer code in the Git repo.

The following is the output log from the verify command.

Verifying "MAKE IT MODULAR"...

Your additional module file:

did not return an Array with the correct number of elements as the second argument of the callback

# FAIL

Your solution to MAKE IT MODULAR didn't pass. Try again!

Even using the http_uc.js solution, it won't pass. Running learnyounode verify http_uc.js I get the following:

I'm a newbie to node . please help me out

I had entirely too much fun working through these exercises and solidifying my node knowledge. Thank everyone who worked on this.

Instead of an official solution I get a 'This socket is closed' error. This is with all the lessons I have tried, I include the output from the HELLO WORLD one.

ACTUAL EXPECTED

"HELLO WORLD" "HELLO WORLD"
"" ""

PASS

Your solution to HELLO WORLD passed!

Here's what the official solution is if you want to compare notes:

error comes back saying something about verify not existing

This is my code:

http = require('http');

urls = [process.argv[2], process.argv[3], process.argv[4]];
out = [];



function getter (url, iterator){
  var temp = "";
  http.get(url[iterator], function(response){
    response.setEncoding('utf-8');
    response.on('data', function(data){
      temp += data;
    });

    response.on('end', function(){
      out[iterator] = temp;
      if(iterator == 2){
        for(var i = 0;i<3;i++){
          console.log(out[i]);
        }
      }
    });
  });
}

for(var i = 0;i<3;i++){
  getter(urls, i);
}

When I test by myself:

What is my error?

Thank you 😄

here's my code (it does not pass the test, even though its right):

#!/usr/bin/env node
var args = process.argv;

if( args.length < 3 ) {
    console.error('ERROR: expected is a filename');
    return 1;
}

var content = [],
    lines = 0,
    fs = require('fs');

content = fs.readFileSync(args[2]).toString().split('\n');

lines = content.length - 1;

if( lines && (!content[lines - 1]) ) {
    --lines;
}

console.log(lines);

On the problem of "http_file_server", the official answer seems to be wrong.
Even I made the same file as the official answer file, I couldn't pass verification.

I submitted a code for verification for the "MAKE IT MODULAE" stage, the "actual" and "expected" were identical, but I still didn't pass the stage, and I got no error, just the results comparison was outputted
here's my code
for the file a.js

 module.exports=function(folder,ext){
         fs=require('fs');
         fs.readdir(folder,function(err,data){
                 if(!err){
                         rex=new RegExp('\\.'+ext+'$');
                         data.forEach(function(f){
                                 if(rex.test(f)){
                                         console.log(f);
                                 }
                         });

                 } else {
                         return err
                 }
         });
 }

and for b.js

 a=require("./a.js");
 a(process.argv[2],process.argv[3]);

and to verify I executed
learnyounode verify b.js

the verify does a check that the module takes the extension but if you are passing in '.' + extension to the module and your module is expecting that, then it'll fail but the message is opaque and it's not easy to figure out why.

For "learnyounode run"
process.argv[2] is undefined
"learnyounode verify" works

I've just completed the lesson HTTP UPPERCASERER where it asks for the HTTP server to only receive POST requests. However the solution doesn't require the server to filter out non POST requests. I believe the solution should send a GET request to see if the server is filtering out non POST requests

Apparently make it modular won't verify if you use:

var readdir = require('fs').readdir;
readdir(dirname, function(err, list){ ... }

instead of:

var fs = require('fs');
fs.readdir(dirname, function(err, list){ ... }

nodeschool/discussions#141

var net = require("net");
function pad(n) {return n < 10 ? '0'+ n : n }
var server = net.createServer(function(socket){
  var d = new Date();
  var s = d.getFullYear() + "-"
    + pad(d.getMonth()+1) + "-"
    + pad(d.getDate()) + "-"
    + pad(d.getHours()) + ":"
    + pad(d.getMinutes());
  socket.end(s);
})
server.listen(8000);

The output is "Error connecting to localhost:3911: connect ECONNREFUSED" != "2014-02-12 20:11"
null != ""
Is there anyone can help me? Thanks a lot.

For the Time Server, the verify command fail to launch, I get connection refused.

No other TCP server is running on 8000 or 8001.
The run command is running correctly and I get the date.

If I run my solution directly, I can get the date with a telnet.

Here the full output when I launch verify:

ACTUAL                             EXPECTED

And my solution:

var net = require('net')

function zeroFill(number) {
    return (number < 10 ? '0'+number : number)
}

var server = net.createServer(function (socket) {
    var date=new Date()
    var strDate=date.getFullYear()+'-'+
                zeroPad(date.getMonth())+'-'+
                zeroPad(date.getDay())+' '+
                zeroPad(date.getHours())+':'+
                zeroPad(date.getMinutes())+'\n'
    socket.write(strDate)
    socket.end()
})
server.listen(8000)

hey there

1st of all - great work - playing around and it's great fun and a learning experience combined 👏

however, i've got an issue with filtering the extensions and such

what about files without an extension?

if i'd like to filter for files without the extension, the solution like

path.extension(file) === '.' + ext

seems wrong to me

my solution was a comparison like

path.extension(file).replace(/^\./, '') === ext

or am i missing something here? :)

My code seems to be passing:

$ learnyounode verify modular.js

but 'MAKE IT MODULAR' is not getting marked '[COMPLETED]' in the main menu.

module.exports = function(path, filter) {

On completing an exercise, it would help to learn node if you showed how you test it.

Hi,

i really enjoyed nodeschool.io - great work!

Have you planed to offer it in other languages? I can help you translate to german if you want.

Especially the hints are not so easy to understand if english is not your native language

I've tried to complete the "http_file_server" course. Verify always tells me my test failed. However, when I copy the solution it fails as well.

Here is the output using the recommended solution:

Verifying "HTTP FILE SERVER"...

ACTUAL:   "Grab us a ugg mate he hasn't got a dropkick. Stands out like a boogie board mate as stands out like bradman. Grab us a ironman no worries trent from punchy grog. Get a dog up ya bogged piece of piss lets throw a larrikin."
EXPECTED: "As cunning as a mozzie bloody trent from punchy pokies. She'll be right fly wire flamin as cross as a jumbuck. Gutful of cockie with lets get some knock. Flat out like a cook heaps as busy as a rollie."

# FAIL

Your solution to HTTP FILE SERVER didn't pass. Try again!

On the time server example, it'd probably be better to recommend strftime instead of moment since strftime is far more unixy since it just implements the string formatting from the unix date command. The time format is just strftime('%F %H:%M', date).

.

I have confirmed this issue by grabbing the solution from the repo.

Here is the output from the verify:

ACTUAL: "{"hour":18,"minute":1,"second":47}"
EXPECTED: "send me a POST"

ACTUAL: "{"unixtime":1377208907000}"
EXPECTED: ""

ACTUAL: ""
EXPECTED: "send me a POST"

ACTUAL: null
EXPECTED: ""

FAIL

Your solution to HTTP JSON API SERVER didn't match the expected output.
Try again!

My first I/O validates line count with an extra line.
the output of :

fs = require('fs');
//console.log(fs.readFileSync(process.argv[2]).toString().split('\n') );
console.log(fs.readFileSync(process.argv[2]).toString().split('\n').length );

is one line longer than the output of the unix utility
wc -l , and to the real number of lines in the file.
but It passes the verify step.
detailed output:

vagrant@precise32:~/stuff$ wc -l wc.js
3 wc.js
vagrant@precise32:~/stuff$ node wc.js wc.js
4

seems that an empty string at the end of the array is counted.

$: node wc.js wc.js

[ 'fs = require(\'fs\');',
  'console.log(fs.readFileSync(process.argv[2]).toString().split(\'\\n\') );',
  '//console.log(fs.readFileSync(process.argv[2]).toString().split(\'\\n\').length );',
  '' ]

Ok all works great ... very cool project.
Unfortunately there is just a small caveat in the last problem.

User need to write code to respond to api request. One of them is the unixtime api.
Time gap between user code execution and provided solution execution could make a false negative test result.

An example here:

ACTUAL:   "{\"hour\":10,\"minute\":27,\"second\":54}"
EXPECTED: "{\"hour\":10,\"minute\":27,\"second\":54}"

ACTUAL:   "{\"unixtime\":1376468974699}"
EXPECTED: "{\"unixtime\":1376468874180}"

ACTUAL:   ""
EXPECTED: ""

One solution is to change api request in the problem to something less picky. I think there are not available solution considering how Workshopper works
Best Regards
Francesco

Hello, I had problems with the array process.argv, my return:
['node', 'path-file.js']

Exercises in the use of the solutions process.argv talks to use the array at position 'process.argv [2], but the two have nothing ... used in position' process.argv [1] ', but when I send command 'VERIFY' he needs me to use the 'process.argv [2] to complete the exercise.

Thank you.

In Time Server task there's a typo in date format. Original quote:

Your server should listen to TCP connections on port 8000. For each
connection you must write the current date & time in the format:

  YYYY-MM-DD HH:MM

I think that time format should look like YYYY-MM-DD hh:mm. Especially it is important for minutes since minutes and months has similar format literals.

The second test (unixtime test) will never be true. The compared expected/actual values we get from Date.now() and will never be the same.
Proposal:
the expectedValue - constant <= actualValue <= expectedValue + constant

On HTTP FILE SERVER, I get:

$ learnyounode verify myprogram11.js

stream.js:94
      throw er; // Unhandled stream error in pipe.
            ^
Error: connect ECONNREFUSED
    at errnoException (net.js:901:11)
    at Object.afterConnect [as oncomplete] (net.js:892:19)

Even when using the proposed solution.

Node is v0.10.15.

Using learnyounode v0.2.16 on node v0.10.21 on Windows7 (standard cmd-shell, no elevated permissions, although I am a local admin), upon learnyounode verify [foo.js] some formatting remains when the application exits back to the command-prompt:

I am trying this exercise https://github.com/rvagg/learnyounode/blob/master/exercises/my_first_io/solution/solution.js

The actual and expect results has difference of 1 char

Why there is -1 because the actual file I tried has exactly 35 lines but test shows 34

Hi

I think that the HTTP JSON API SERVER exercise doesn't say which port you should use. By going through the solution I found out that you'll pass it as parameter. It might be good to add it to the problem description.

Thanks!

I wrote out my code for the exercise and it was failing with the following error:

var fs = require('fs');
var http = require('http');

var path = process.argv[2];

var server = http.createServer(function (request, response){
    var src = fs.createReadStream(path);
    src.pipe(response);
});

server.listen(8000);

throw er; // Unhandled stream error in pipe.
^
Error: Parse Error

I then tried the solution code in the repository (see below) and it too is failing with the same error.

var http = require('http');
var fs = require('fs');

var server = http.createServer(function (req, res) {
  fs.createReadStream(process.argv[2]).pipe(res);
  res.end();
});
server.listen(8000);

When I look at https://registry.npmjs.org/learnyounode with Chrome is says the identity is verified.

The answer for this exercise contains:

...
          if (err)
            return console.error(data)
...

Shouldn't it be

...
          if (err)
            return console.error(err)
...

?

I've been trying to verify my solution to time server and it seems to hang and do nothing.
It comes up with -

Verifying "TIME SERVER"...
ACTUAL EXPECTED

Then nothing for about 5 minutes.
It then says -
"Error connecting to localhost:8000: read ECONNRESET" != "2013-11-05 18:32"

FAIL

I've tried this with the official solution too and I get the same problem.

I'm running windows 7. Do you have any idea why I might be encountering this problem?

I haven't ruled out that this is a PEBKAC yet. This is the solution I have for HTTP file server:

var http = require('http')
var fs = require('fs')

if(process.argv.length < 3) {
  console.error('you forgot to give me a file')
  process.exit
}

var file = process.argv[2]

var server = http.createServer(function (request, response) {
  var stream = fs.createReadStream(file)
  stream.pipe(response)
})

server.listen(8000)

When I hit this in a browser (after passing in an ASCII file on the filesystem), it always returns consistent (and expected) results. When I use learnyounode verify, it always returns different (inconsistent) results that don't match expected.

Couple of examples:

$ learnyounode verify httpfileserver.js
ACTUAL:   "As cross as a cane toad no worries it'll be bizzo. Come a grouse bloody you little ripper swag. As cross as a bush bash my shazza got us some thingo."
EXPECTED: "We're going pot also mad as a struth. Lets get some slabs when he's got a massive grog. We're going sleepout how as cross as a cockie. Watch out for the ankle biter no dramas come a rotten. Watch out for the captain cook mate stands out like a piker."

Another one (expected is the same as above):

ACTUAL:   "You little ripper freo bloody as cross as a crook. As cross as a esky and as stands out like corker. Stands out like a chrissie how grab us a jillaroo. Mad as a prezzy to as cross as a slacker."

I have a problem using port 8000 on a windows 7 machine this port is being used by the system, for some purpose or other. I am afraid that finding what is actually using this port maybe a little beyond me and is certainly beyond the time I have available. I have seen in other posts that you were going to allow users to input the port on the command line. Has this been implemented yet? If not is there a workaround?

running learnyounode doesn't return anything in terminal in Linux Mint 15 (fresh install of node.js)

Thrown error:

Error connecting to http://localhost:14593: connect ECONNREFUSED

but when I run by node directly, it works correctly.

While when I try to run it again and again, sometime it will pass..., i think it may a bug?

We could use Array.prototype.forEach instead plain for (var i = 2; i < process.argv.length; i++) { ... }, couldn't we?

So the solution might be

var total = 0;

process.argv.forEach(function(item) {
  //we need to exclude first and second items
  //so we could just filter them as NAN
  total += +item ? +item : 0;
});

console.log(total);

Hey,

i get an error on verify the last chapter:

This is my 13.js-file:

var url = require('url');
var http = require('http');

var port = parseInt(process.argv[2]);

var server = http.createServer(function (req,res) {

var urlparam = url.parse(req.url, true);

if(req.url.match(/\/api\/unixtime/)){
    var datum = new Date(urlparam.query.iso);

    var objt = {
        unixtime: datum.getTime()
    };

    res.writeHead(200, { 'Content-Type': 'application/json' });
    res.end(JSON.stringify(objt));
}else if(req.url.match(/\/api\/parsetime/)){
    var datum = new Date(urlparam.query.iso);

    var objt = {
        hour: datum.getHours(),
        minute: datum.getMinutes(),
        second: datum.getSeconds()
    };
    res.writeHead(200, { 'Content-Type': 'application/json' });
    res.end(JSON.stringify(objt));
}else{
    res.writeHead(404);
    res.end();
}

});

server.listen(port);

I found an interesting bug i wanted to fix. :/

dennis learnyounode $ learnyounode verify myprogram.js 
Verifying "TIME SERVER"...

# FAIL

Your solution to TIME SERVER didn't match the expected output.
Try again!

Sorry, but i don't think port 66062 exists.

Thankfully after just attempting response.toString() in the final lesson (HTTP JSON API SERVER) I remembered there was a javascript way of turning objects into a json string.

However somebody else may not know about this and there was no mention of it in the hints or instruction or in any of the previous lessons.

Just thought I would point this out.

I'm interested in adding a simple test harness to guard against regressions as alluded to in a recent PR.

I can't imagine it's too difficult since workshopper is essentially a test framework already.

Would this work be useful to the project in your collective minds?
