expressworks's Issues

Working (incorrect) solution to exercise 3

The proposed solution in good_old_form does not pass in my terminal. However, below is a working solution for all that it is worth:

var express = require("express");
var app = express();
var bodyparser = require("body-parser");

app.use(bodyparser.urlencoded({extended: false}));

app.get("/form", function(req, res) {
    res.send(req.body.str.split('').revers().join(''));
});
app.listen(process.argv[2]);

expressworks #7 error

having an issue passing exercise 7:

Spelling mistake/unclear explanation in "Ex4 - STATIC"

Under HINTS, the first line does not make sense as it says:

"This you someone can call static middleware:
app.use(express.static(path.join(__dirname, 'public')));"

:

Good OLD Form never send form in POST body

It's always empty.

Official WHAT'S IN QUERY solution doesn't work

The official solution is:

    var express = require('express')
    var app = express()

    app.get('/search', function(req, res){
      var query = req.query
      res.send(query)
    })

    app.listen(process.argv[2])

but it doesn't work.

My solution was:

var express = require('express');
var app = express();

app.get('/search', function (req, res) {
  var query = req.query;
  delete query.__proto__;
  res.send(JSON.stringify(query));
});

app.listen(process.argv[2]);

I don't know if it's a good solution, but it worked.

Verification failed with an error for all the exercises

Jade exercise cannot be completed

I'm using the exact same code as per the solution @ https://github.com/azat-co/expressworks/blob/master/problems/jade/solution.js

However, expressworks still deems this a fail:

The 'jade' package is also installed locally, and globally.

Specify Node version.

First of all, this is a great app! Thank you for putting this together.

This ran fine using Node v0.11.8, but I was initially using an older version of node (v0.8.20) and kept getting errors.

It might be good to specify the node version on packages.json.

Hello World task specification unclear

problem.txt specifies that the app should be run on 'localhost:3000', but later specifies that the port number will be provided by expressworks.

I have been recently working on the learnyounode & stream-adventure workshops so I assumed that the default of preferring process.argv[2] was still applying to this track.

Either the problem specification should clarify that port 3000 will be used, or the test should be updated to use a random port number which is supplied to the script.

Exercise 8 broken

"Good Old Form: Official solution gives: Error: Cannot find module 'body-parser'

The official solution:

    var express = require('express')
    var bodyParser = require('body-parser')
    var app = express()    
    app.use(bodyParser.urlencoded({extended: false}))
    app.post('/form', function(req, res) {
      res.send(req.body.str.split('').reverse().join(''))
    })   
    app.listen(process.argv[2])

gives: Error: Cannot find module 'body-parser'

But this works:

var express = require('express');
var app = express();
app.use(express.urlencoded({extended: false}));
app.post('/form', function(req, res) {
    res.end(req.body.str.split('').reverse().join(''));
});
app.listen(process.argv[2]);

JSON ME Unable to produce answer

My answer below is almost identical to the official answer and produces the same output, which is not "correct" in that it spans multiple lines and the correct output is all one line. I don't see anything wrong with my code.

var fs = require('fs');
var express = require('express');
var app = express();

app.get('/books', function(request, response) {
fs.readFile(process.argv[3], function(error, data) {
if (error) {
console.log(error);
}
response.json(JSON.parse(data));
});
});
app.listen(process.argv[2]);

Good Old Form

My Code :

var app = express()
app.use(bodyparser.urlencoded({extended:false}))

    req.body.str.split('').reverse().join('')

Use of middleware in form post

[Express.js newbie!]

After having a hard time with error messages from Connect in the Form Posting exercise, I Googled the issue I was facing and came across this Stack Overflow question:
http://stackoverflow.com/questions/22209388/node-express-module-throwing-no-method-errors

The responder suggests the use of body-parser, as does the list of supported middleware on the Express.js website.

Am I mixing things up, or is the exercise outdated?

My solution, for reference:

var port = process.argv[2]

var express = require('express'),
    bodyParser = require('body-parser')

var app = express()
app.use(bodyParser.urlencoded())

app.post('/form', function(req, res) {
  res.end(
    req.body.str.split('').reverse().join('')
  )
})

app.listen(port)

Verifying a solution goofs up terminal colours in Windows (in cmd, PowerShell, and others)

How?

ExpressWorks currently uses Workshopper v0.33 which colours code snippets with pygmentize. It passes the parameter terminal256 to pygmentize - but Windows terminals don't support 256 colours (as you saw they interpret these colours very differently!).

v0.4+ of Workshopper doesn't have this problem (it uses msee instead of pygmentize).

What's the fix?

Upgrade to v0.7.2, which is the newest version before v1. This didn't break anything when I tested it (briefly).

Expressworks keeps lingering processes running on Mac OS X

I have had two people running on two separate machines with weird Expects results.

From what I can tell it is due to some of the processes not being killed after the exercises have been completed. Because most of the exercises all run on the same port number, we are actually verifying to an old service.

running

$ ps aux | grep node

on these machines showed around 5 / 6 processes all belonging to the express works workshop.

Stray node processess

Users need to run killall node before verifying some exercises. See:

• #42
• #32

Install required additionals as dependencies instead of separate installation

express was not installed by default and hence, solution didn't worked. Since, I already had some knowledge regarding node, it was easy to find, but for absolute beginners it's hard to figure out what's going wrong. Please add all required modules to complete the challenges as dependency of the package.

STATIC - confused about instructions - where to learn more

I am finding the ExpressWorks instructions incomprehensible. Perhaps I am missing some prerequisites. I’ve written out my questions below to show the level of ignorance I am coming to this learning session with. If you have suggestions about where to go to learn what I need before I start, please let me know.

For example, Exercise 2 of 8 (static) says:

Please don't use ANY routes like app.get. ONLY static.

I wonder:

1. What is a route?
2. How can I learn about app?
3. Static? Static as opposed to dynamic. What does that mean?

Your solution must listen on the port number supplied by process.argv[2].

I wonder:
4. What listens?
5. Is this like the Hello World one where I used this:
var app = express();
...
app.listen(process.argv[2]);

This is how you can call static middleware:

I wonder:
6. What is static middleware?
7. Where can I learn about it?

For this exercise expressworks will pass you the path:

app.use(express.static(process.argv[3] || path.join(__dirname, 'public')))

I wonder:
8. Is app var app = express();?
9. If so, what is express?
10. Where did the path variable come from?

This what I think is supposed to happen: process.argv[3] points to an HTML file. I am supposed get this HTML file and send it back in a response. I’m supposed to wait for a request from process.argv[2], but I don’t know if I’m supposed to parse that request in any way.

Selecting/PressingEnter on any chapter/challenge/activity just hangs the git_bash, nothing happens

I'm using GitBash in windows 8. I've earlier used planetproto & learnyounode and things works perfect. This one just hangs after selecting any challenge.

param_pam_pam could've used app.param

It'd be quite cool to show users how they can profit from app.param.

app.param('message_id', function(req, res, next, messageId) {
    req.computedHash = require('crypto')
        .createHash('sha1')
        .update(new Date().toDateString() + messageId)
        .digest('hex')
    next();
});

app.get('/:message_id', function(req, res, next) {
    res.send(req.computedHash);
});

Maybe worth mentioning there are two ways to approach this problem? Showing the beginners not everything needs to be handled in a route handler might be a nice tip!

WDYT?

stylish css doesn't accept solution

Big time noob here. Here is the code:

var express = require('express')
var path = require('path')
var app = express()
app.use(require('stylus').middleware( process.argv[3] + "/*.styl" ))
app.get('/main.css', function(req, res) {
res.end()
})
app.listen(process.argv[2])

main.css is being generated, but the GET doesn't fetch it. Please help!

Expressworks #8

I can't understand why this is not accepting my code, the output is the same. here is my program.js:

var express = require('express')
var app = express()
var fs = require('fs')

app.get('/books', function(req, res){
  var filename = process.argv[3]
  fs.readFile(filename, function(e, data) {
    if (e) return res.send(500)
    try {
      books = JSON.parse(data)
    } catch (e) {
      res.send(500)
    }
    res.json(books)
  })
})

app.listen(process.argv[2])

And this is what the response is to "expressworks verify program.js"

Incompatible with Express 4

The workshop is incompatible with the version 4 of Express.

The main problem is with the changes in middleware whose names have changed and are now unbundled from Express, this needing to be npm installed. This affects primarily good_old_form.

I've also add some errors during verify but couldn't attribute it with certainty to Express v4.

Hello World Fails

The sample code for Hello World! is incorrect. The app.get statement directs uses to write:
app.get('/', function(){...})

when the correct answer is
app.get('/home', function(){...});

"Cannot POST /form" in Good Old Form lesson.

I'm getting this error when trying to run or verify my solution. I've also tried the solution in the solution.js but it didn't work as well. I'm on Windows 7.

One thing it's worth mentioning is that I installed the "connect" module, since in the problem description, is said that "Express has urlencoded() middleware (from Connect library)". I'm not sure if I have to install it or if it is already a dependency of the Express module.

solution verification for 3 problems are broken

Exercises you can steal: https://github.com/timoxley/express-koans

Hey I've got an 'express koans' thing I set up a while back: https://github.com/timoxley/express-koans

I'd thought to rejig them into workshopper, but I don't really use express anymore so meh.

Just thought I'd let you know you're welcome to steal any exercises from there if you think they're useful.

problem 7 & 8 expected solutions are wrong

straight up wrong

expressworks verify program.js
Verifying "WHAT'S IN QUERY"...

ACTUAL:   "{\"results\":\"recent\",\"type\":\"quote\",\"page\":\"7\"}"
EXPECTED: "Cannot GET /search/?results=recent&type=quote&page=7"

# FAIL

Your solution to WHAT'S IN QUERY didn't match the expected output.
Try again!

basically you can pass this problem by omitting the route. If you use the provided solution (or a correct solution as in my case) you do not pass this problem. I would fix it myself but I'm unfamiliar with the way the expected solution is generated in https://github.com/azat-co/expressworks/blob/master/problems/whats_in_query/setup.js
Also found problem 8 does something similar. I tried npm install express in these directories just in case that was the issue but it is not. Let me know if you have trouble reproducing the bug.

jade expected output

the expected output is not right it seems. it is expecting "Hello World!"--which the solution for question 1.

good old form: does method--get vs. post matter?

Verifying "GOOD OLD FORM"...

ACTUAL EXPECTED

---

"Express.js rocks!" != "Cannot POST /form"

FAIL

when change app.post to app.get, the solution passed but it should not be the case

ExpressWorks Hello, World

Wow. This is pathetic. I can’t get past the first exercise. Can anybody tell me what I’m doing wrong?

Some info. I am working on a Mac. Below are the commands that I type in the terminal and info on the output. After that is my code.

$ sudo npm install express --save
[entered password, much output, nothing in red...I think it went okay]
$ killall node
No matching processes belonging to you were found
$ expressworks run Express.js
35557
Cannot GET /home

Here’s my code
Express.js:

var express = require('express');
var app = express();
console.log(process.argv[2]);
app.get('/', function(req, res) {
        res.end('Hello World!');
})
app.listen(process.argv[2]);

Verification for task 4 is broken

Rather that attempting to verify against the correct template, the task simply compares to a failed GET
