Hi, Ethan

I am really enjoying your book.
Great work!

I have written the code myself and I also have checked out your repo(ch07 tag).
I have a problem with cross page testing.
The first test always fails.
Please see the screen shot.

Hi,

I have cloned this repository, and as mentioned in book, was trying to checkout ch04. But not able to .
Is the tags defined ?

Thanks,
arbarik

Hi Ethan. I can't get the nursery rhyme examples in Chapter 7 to work. Line 23 in nursery-rhyme.handlebars causes the error: Uncaught ReferenceError: Handlebars is not defined

Line 23:
var nurseryRhymeTemplate = Handlebars.compile($('#nurseryRhymeTemplate').html());

Any suggestions?

1)- the last entry within an object ( key-value pairs) ends with a comma
in all the code. Thus Causing the speckling of the gutter with red marks
within the ide.
2)- require(); has Many ' ' omissions surrounding the parameter,

3)- package.json seems out of date

You have structure spelled as Strucutre in the headings.

Given a route defined as:

app.get('/error', function(req, res) {
  throw new Error('Testing');
});

When requested, the error event is not emitted.

Thoughts?

I would appreciate if you fill this function below ..

Chapter 8 and Chapter 13:
function saveContestEntry(contestName, email, year, month, photoPath){
// TODO...this will come later
}

The completed sample is required to operate at Heroku server hosting
because of the following error

Error: EXDEV: cross-device link not permitted, rename '/tmp/upload_f8c7f27f5fc96f1455e35cb30e2c7399' -> '/app/uploads/property/photo/1453171290731/사당휴브리지오피스텔검색결과.jpg'

And
i would like to done my first sample works..
http://helloslow.herokuapp.com/

On page 46 one needs to install zombie, this will, however, install version 4.1.0. 4.1.0 is for some reason not supported (assaf/zombie#909) and thus I installed 4.0.8.

I made the shift over to the grunt setup at the end of chapter 5. However, when I ran 'grunt' a few errors occurred.

Two of the tests, 'public/qa/tests-about.js' and 'public/qa/tests-global' were erroring out saying that 'assert' was not defined. So, I added in chai's assert via require, and then ran 'grunt' again.

For the tests-about.js file, now it was showing that '$' was not defined. So I found the jQuery npm module and after installing used the require to bring that in. However, after that it said that undefined was not a function.

For the tests-global, it said 'document is not defined'. So I did a little searching and thought possibly that I needed to bring in jsdom. I gave that a go but after running grunt it came back with 'Unspecified AssertionError'.

Any ideas? Thanks a lot!

Hey Ethan,

First want to say that I'm really enjoying working through your book. I've wanted to learn Node and Express for awhile, I this is the right book for me.

However, I'm having some issues with the Cross-page tests in Chapter 5. I've seen a few people post about these tests, but I haven't been able to find out what I'm doing wrong. I've been poring over the docs for Zombie, but they've failed to spotlight the problem so far.

I'm receiving this error for both the hood-river and oregon-coast tests. It looks like browser.field('referrer').value is returning null and I can't figure out why. I've been stuck on this for a bit and I may just skip it for now, but I thought I'd reach out.

Thanks.

hello , i learn ch05. but when i open two terminal . the first code 'node meadowlark.js'. the second code ' mocha -u tdd -R qa/tests-crosspage.js 2>/dev/null' . it's nothing to show me in the first terminal. can you help me . thank you very much ----- orz

Been a fanboy of your excellent manual since I found it under my Xmas tree last year--and a close student of this repo as I've jimmied the code over the past month, your routes/handlers refactor being a particularly illuminating revision.

In the interest of wringing every last iota of template value out of your book, and since nobody's yet bothered you about it, may I just take a moment to formally beg you share tags for the finished states of the Security and API chapters?

I've been trying to manually refactor the code in Chaps 18 & 19 to match the repo on my own, but it's been tricky. Some time with Chapter 20: Debugging will likely help get me through my troubles, but a reference solution to those set-ups would be a godsend: working with Passport and various APIs was a big motivation to get this far!

Much obliged for your consideration, anyways, and also for the book. Seriously classic stuff.

Hi -

I'm working on the weather widget example. The template renders, but it does not render the Each Block. A console.dir(partials) on the template returns "partials is not defined". I've reduced the weather locations array to a single location and name for testing.

weather.handlebars:

<div class="weatherWidget">

          {{#each partials.weather.locations}}
              <h3>{{name}}</h3>
              {{/each}}

      {{! Below code is rendering}}
          <small>Source: <a href="http://www.wunderground.com">Weather Underground</a></small>
</div>

Thanks!
Robert

i have already create an custom.handlebars in views/layouts/. it didn't work. eventhough i set layoutDirs when create the engine.

is there something wrong with my code?

app.get('/custom-layout', function (req ,res) {
  res.render('custom-layout', {layout: 'custom'});
});

here is error info:

Error: Failed to lookup view "custom-layout" in views directory "/home/zhlin/Co
de/Express/chap3/site/views"
...

I'm getting 2 failures. 1 for sure is the oregon page as it's not written but the other is dumbfounding me. I've checked spelling and can't figure it out.
**** (i've seen an earlier thread on zombie versions too so I've downgraded to version 3.1.1)

the error is

Cross-Page Tests
1) requesting a group rate quote from the hood river tour page should populate the referrer field
2) requesting a group rate from the oregon coast tour page should populate the referrer field
✓ visiting the "request group rate" page directly should result in an empty referrer field

1 passing (4s)
2 failing

1. Cross-Page Tests requesting a group rate quote from the hood river tour page should populate the referrer field:
   Error: timeout of 2000ms exceeded. Ensure the done() callback is being called in this test.

2. Cross-Page Tests requesting a group rate from the oregon coast tour page should populate the referrer field:
   Error: timeout of 2000ms exceeded. Ensure the done() callback is being called in this test.

**** note, just saw the missing {{section}} added to the request group rate page to allow jquery, I've added that and now all 3 of the test fail for the same reason, exceed timeout for done()

here's the error from terminal

Creating this as an FYI for the next update to the book. express3-handlebars has been renamed to express-handlebars. See here.

@EthanRBrown you may have already seen it but I didn't see it in the issue tracker.

I'm following the Chapter 18, 'Security'. I was able to get the login working with no problems, but I can't access the user information through req.user.

I googled the problem and everyone said that the problem is that express-session isn't correctly enabled, but I'm using sessions in the app (like the flash thing) and the setup is equal to the project files:

app.use(bodyParser.urlencoded({extended: true}))
app.use(bodyParser.json())

var MongoSessionStore = require('session-mongoose')(require('connect'))
var sessionStore = new MongoSessionStore({
    url: credentials.mongo[app.get('env')].connectionString
})

app.use(require('cookie-parser')(credentials.cookieSecret));
app.use(require('express-session')({
    store: sessionStore,
    resave: false,
    saveUninitialized: false,
    secret: credentials.cookieSecret,
}));

installing zombie produces this error.

In Chapter 16, you briefly mention your bundle module, and show how to use it, but you don't explain it. I don't understand how the 'stuff' in the config.js file relates to stuff like this:

{{#each _bundles.css}}

{{/each}}

I understand, I think, what I'm doing when I bundle, but you aren't explaining what happens. How would I know, or where would I find that _bundles.css relates to bundles.clientJavaScript.contents (which is what I'm pretty sure is what's happening here)?

I'm using the downloaded code to test the app as I work through the chapters and I'm running into a problem:

I am new to Node and Express. I like to test the code as I read along your book.
I cannot seem to get the code to work when I test it. Here is what I have done.

• First i clone your repo, then checkout tag ch04.
• run npm install
• run node meadowlark.js
  Then I received the following error.
  

I am not sure if i have done something wrong. Please help. Thanks

id="fieldName" is used twice. Shouldn't all IDs have unique names?

I have been working in Chapter 9 for Cookies and Sessions. With my own web app that I have been building as I follow along with your book is not able to load my root page when I attempt your example. The console shows errors with express-sessions depreciated with options for resave, saveUninitialized, and req.secret (provide secret option). I tested your ch10 tag to see how to debug my mistake and found the same error.

I then went and looked up the express-sessions on github for more info. I found the following code with one option added:

This works:
var session = require('express-session')
app.use(session({secret: 'keyboard', resave: true}));

This produces errors:
var session = require('express-session')
app.use(session({secret: credentials.cookieSecret, resave: true}));

It is unclear how I can refactor your example to work, so the secret key will be hidden via module.export in the credentials.js file. Please let me know your advice for correcting this issue. Thanks.

With the credentials.js file not working properly I have replaced the code with environmental vars. When I run the ./lib/email.js to test the functionality from this chapter example, the server is throwing an error stating there is no method 'send' at the line:

emailService.send(...);

I might be wrong, but are we able to access the send as a method when it is placed within the return statement of the email.js file?

I'm a noob who does not know how to diagnose this problem. I'm on page 44 and I have just added the pageTestScript. Upon running the site the qa js files produce a 404 error message when I inspect the page source. everythin loads but the tests-.js files.

My code is typed identically to the book. I upgraded from express3-handlebars to express-handlebars and made sure package.json reflected these changes. It looks like this.

in package.json:

"dependencies": {
    "express": "^4.12.3",
    "express-handlebars": "^2.0.0"
  },

in meadowlark.js:

var handlebars = require('express-handlebars').create({defaultLayout: 'main'});
...
app.use(function(req, response, next){
    response.locals.showTests = app.get('env') !== 'production' && 
    req.query.test === '1';
    next();// pass control to the next handler
})
...
app.get('/about', function(req,response){
    response.render('about', { 
        fortune: fortune.getFortune(),
        pageTestScript: '/qa/tests-about.js' 
    });
});

in main.handlebars:

{{#if showTests}}
        <div id= "mocha"></div>
        <script src="/vendor/mocha.js"></script>
        <script src="/vendor/chai.js"></script>
        <script>
            mocha.ui('tdd');
            var assert = chai.assert;
        </script>
        <script src="/qa/tests-global.js"></script>
        {{#if pageTestScript}}
            <script src="{{pageTestScript}}"></script>
        {{/if}}
        <script>mocha.run();</script>
    {{/if}}

I get this error:

I do not know what the './credentials.js' for and how to make it can find it?

When you install express3-handlebars - as the book suggests - npm gives you a deprecated warning because it was moved to express-handlebars. So I used express-handlebars until now because I seem to be reasonable to use the latest tools and I did not think that this would break anything.

npm WARN deprecated [email protected]: THIS PACKAGE HAS BEEN RENAMED TO: express-handlebars

At least until the following error occurred after I added the weather partial:

Error

    at Module._compile (module.js:460:26)

    at Object.Module._extensions..js (module.js:478:10)

After finding this StackOverflow post with the same Error code (but no solution) I found out, that it had something to do with the res.locals.partials

If I exchange express-handlebars with the deprecated express3-handlebars my code works fine. Also, when I update the chapter8 solution code to express-handlebars the same error occurs.

Does anyone know why it does not work anymore? Maybe a workaround/different solution?

line 90:
var sessionStore = new MongoSessionStore({ url: credentials.mongo[app.get('env'].connectionString });

should be

var sessionStore = new MongoSessionStore({ url: credentials.mongo[app.get('env')].connectionString });

( ie ('env'] -> ('env)] )

When I run the example code of this chapter, after I filled the form and uploaded png files, clicking the sumbit button will prompt to submit a file. It seems that the jquery-file-upload plugin has sent the request when uploading files. The form submission and the file upload are not synchronized.

I've tried multiple versions of zombie but I haven't been able to solve this issue. My tests fail with error saying it cannot read value of null.

assert(browser.field('referrer').value === referrer);

I have the latest versions of Xcode command line tools and node.js

I notice that the inclusion of the partial {{> weather}} in the home.handlebars file is getting confused between the name of the widget weather.handlebars and the partial variable located in res.locals.partials.weather because a saw this error on my browser:

Error: You must pass a string or Handlebars AST to Handlebars.compile. You passed [object Object] at Object.compile...

So, I decided to replace res.locals.partials.weather with res.locals.partials.weatherData. Finally, the weather.handlebars file will look like this:

<div class="weatherWidget">
  {{#each partials.weatherData.locations}}
    <div class="location">
      <h3>{{name}}</h3>
      <a href="{{forecastUrl}}">
        <img src="{{iconUrl}}" alt="{{weather}}">
        {{weather}}, {{temp}}
      </a>
    </div>
  {{/each}}
  <small>
    Source: <a href="http://www.wunderground.com">Weather Underground</a>
  </small>
</div>

These changes worked well for me. Hope it helps.

I'm a bit confused about the use of connect-rest.

The third passed parameter is the 'callback' function. What exactly this function does? It returns what you want as json? Why the first argument is "null"? The documentation doesn't seem to explain much about this

on pg 46 chap 5.
My tests first 2 test cases failed (i.e hood-river and oregon-coast) because it couldn't find done(),
(i dont know why) but it worked fine after i moved it out of function browser.visit(..).

In ch7, there's a section that dives into the concept of "Sections" within your view. Cool way to use Handlebars helpers but I wanted to offer some feedback to make it a little clearer:

1. You should explain what options.fn() does. I had to go to the Handlebars site to find a reference to it and even then it wasn't very clear on what it actually does.
2. The section in the book ends without explaining where to add the _section.head & _section.jquery code. I assumed it was main.handlebars so I added it there.
3. There were no instructions on how to reference the new 'jquery-test.handlebars' template so I just created a simple route to call it. The book should mention something about that.

when initially installing the most recent version of connect-rest module (which surpassed v0.9.12),
I was getting the following error:
"TypeError: rest.get is not a function"

re-installing with version 0.9.12 (as you have it right now) seemed to resolve the error

Hi,
thx for the book and this repository. After checking out ch13 I am facing the following issue:

1. node meadowlark_cluster.js
2. browse to hood-river and add a tour to the cart
3. checkout
4. error - 404
   (everything works fine when running meadowlark.js directly... the problem seems to be around the clustering(

It looks like the express framework throws an error when rendering the check out

app.get('/cart/checkout', function(req, res, next) {
    var cart = req.session.cart;
    if (!cart) next();
    res.render('cart-checkout');
});

Error: Can't set headers after they are sent.
at ServerResponse.OutgoingMessage.setHeader (http.js:689:11)
at ServerResponse.res.set.res.header (/Users/kimkopowski/nodeJs/web-development-with-node-and-express/node_modules/express/lib/response.js:551:10)

help or comment appreciated!

I am following the book and I get this error when I try to start my server. I tried to install the module express-session but doesn't work. It says

throw err;
Cannot find module 'express-session'

on this line - app.use(require('express-session')({ store : sessionStore }));

How can i solve this problem?

where is the credentials.js file for connecting to mongolab, chapter 13 page 148

Up through chapter 5 I have been able to successfully run your examples. However, when I get into this chapter, I am finding many issues. First, to get the tests-global.js file to run I have to remove the if conditional statements. I am unable to apply ?test=1 to the query string and have it initiate the tests you have established so that we can hide the testing functionality.

Second I placed this code in the home.handlebars file to get the test to run with the if conditionals removed. When I run this test on the home page, I do see the global test run on the browser with 0 passes and 1 failure. However, I find an error with the assert statement also displayed in the browser:
AssertionError: Unspecified AssertionError

I reviewed the documentation for chai assert statement (http://chaijs.com/api/assert/#assert) and find we should be using a form as follows: assert(expression, message) but your code is not written to this format. If you could please provide some clarification?

I'm wondering how doing that:

app.get('/about', function(req, res) {
 res.render('about')
})

Can render the file views/about.html. I didn't specify anywhere where my views folder is. Taking a look on the source of express-handlebars.js I can see that the file set two pathnames, one for the 'layouts' and other for 'partials'. But I don't see anywhere a reference to views/. From where this is coming from?

Hello @EthanRBrown

I am really enjoying the book so far. I was reading through the example code snippets for the Providing an API section of Chapter 6 when I came across a couple typos (or at least what I thought may be typos). I wasn't sure if this was an appropriate place to bring these to your attention as they aren't part of the Meadowlark app.

First one I noticed was on page 66 (hard copy) in the first paragraph of the Providing an API section. It says

Examples 6-11 and 6-12 use the following "products" array...

I wasn't sure if this was supposed to say "tours" as that is what the array is called or if you were just referring to it as products as tours are a product a tourism company provides.

Secondly, in Example 6-12 where you format for text/plain you are sending the toursXml string and not the toursText string.

Apologies in advance if these have already been fixed in the eBooks. I just purchased the hard copy a couple days ago so assumed it was a recent version.

From the end of Chapter 14, with the code from github I am seeing the following.

TypeError: Cannot read property 'requiresWaiver' of null

I have deleted the node_module directory and reinstalled using npm install.

When I'm using formidable and upload image fields in forms with enctype=multipart/form-data, I'm getting "invalid csrf token" error message. When I remove enctype from the form, it works.

Any ideas?

Thanks

Hi! dear my friend

your book is great for me
but now have problem
I can't solve this problem
let me know how to fix it

doesn't npm stands for node package manager?

I came from front-end to back-ebd {{{body}}}of handlebar is close to data-binding in AngularJS and it causes troubles. Any sugesstion/replacement except Jade?
