The errata list is a list of errors and their corrections that were found after the product was released.
The following errata were submitted by our customers and have not yet been approved or disproved by the author or editor. They solely represent the opinion of the customer.

7, 8,10
Examples detailed below |
Safari doesn't list page numbers.
Example 7-2, 8-18, 10-24:
define([... 'views/Status'],
should be:
define([... 'views/status'],
Example 8-8:
define(['SocialNetView', 'models/Contact', 'views/Contact',
should be
define(['SocialNetView', 'models/Contact', 'views/contact',
In each, not the case of the last view. Starting with Example 7, none of these work on Linux, which has a case-sensitive file system. Changing the code to lower case fixes this.
This is already marked on the github repo, by somebody else.

On page 10, the text and code suggests that this ternary operator
name ? name.toLowerCase() : ''
involves setting the name variable.
"Inside the switch statement I used a ternary operator as shorthand for an if/else statement:
name ? name.toLowerCase() :: ''. This is equivalent to a much longer block
of code that checks whether the name variable exists, and if so, returns it as a lowercase
string, or otherwise sets it to an empty string for comparison:
if ( null != name ) {
name = name.toLowerCase();
} else {
name = '';
}"
As it stands, I think this will cause confusion. The text should be changed and the "equivalent" code becomes
if ( null != name ) {
return name.toLowerCase();
} else {
return ";
}

Example 2-8 |
The line:
script(script(type='text/javascript')
var socket = io.connect('http://localhost:8080');
...
Sould be:
script(script(type='text/javascript').
var socket = io.connect('http://localhost:8080');
...
The period at the end of the `script` line is missing in the text, and in the code samples on github.

Every path:
public/js/lib/backbone.js
public/js/lib/jquery.js
public/js/lib/require.js
should have /libs/ instead of /lib/.

Why use relative path in: templates: '../templates' ?
templates: '/templates' is enough.

Example 6-15 |
When at the end of chapter 7 and testing the reset password functionality, this generates an error on the resetPassword.jade template on:
extends layout
no such file or directory '/Users/dev-admin/Documents/Projects/SocialNet/views/layout.jade
which shows the path is wrong - it should look in the public directory.

At page 72 the author uses a config variable like
var config = {
mail: require('./config/mail')
}
but does not explains what is will contain and the folder structure ./config/mail does not exists.

Example 6-19 |
a mail.js file is expected in the code block:
var config = {
mail: require('./config/mail')
};
but the contents of the mail.js are never discussed or clarified. Missing this, the application crashes every time, as the Account model will not instantiate.

In the second paragraph after the code sample:
"...the view's HTML template to Underscore's ._template function."
should be:
"...the view's HTML template to Underscore's _.template function."

second paragraph |
Where you say:
Because the StatusView class defines the list item (<li>) as the placeholder,
the declaration of the StatusView view class is missing in the chapter.

Bottom, first paragraph |
The text states:
Next, AccountSchema is defined?take special notice of the email field that has its index property set to true.
However, the code listing on the page doesn't show the index property but only shows the unique property. Please clarify how the index property should be set.

Under Backbone, first paragraph |
Talking about the router, the text states:
it is the router?s job to kick off the data population tasks, authenticate the user, and move between the new views.
About the part: 'authenticate the user'
Is this not the task of SocialNet.js?

Putting it together |
At the end of chapter 7 when trying the code, after the login nothing happens. The code in register.js only logs the data instead of going to the index. I've changed the code and send you a pull request.

At the end of chapter 7 you have omitted the declaration of the SocialNetView view class. When following the chapters and adding code yourself, the code won't run.

Examples 7-15 and 8-24 |
In both code snippets from Example 7-15 (The account model) and 8-24 (The updated account.js model), there is a Status argument that is never passed.
module.exports = function(config, mongoose, Status, nodemailer) {
The problem is in file models/Account.js, that defines the moongose Account model.
In the app.js, from both chapters 7 and 8, the Account model is created without a Status argument.
The error related to this code occurs when nodemailer is used, in the function Account.forgotPassword.
As the third argument in app.js is put into the Status argument, nodemailer becomes undefined.
So, the error is:
TypeError: Cannot call method 'createTransport' of undefined
To corret this error, just remove the Status argument from Examples 7-15 and 8-24.

1st paragraph |
In chapter 8, section "Contact List Template", it says:
"Looking back at the Contact List view in Example 8-2, the contacts will live inside an unordered list (<ul>) HTML tag."
Though, looking at Example 8-2, there is no <ul> but a <div>.
As the Example 8-5 defines the contact.js view with a 'li' tagname, a contact is present with a bullet point on the side.

Example 8-13 |
In Example 8-13 (The account model?s addContact method), a contact object is created as follows:
var addContact = function(account, addcontact) {
contact = {
name: addcontact.name,
accountId: addcontact._id,
added: new Date(),
updated: new Date()
};
The 'name' of the contact being added (addcontact) is copied to the 'name' property of the new 'contact' object.
This name property is an object itself, composed of 'first' and 'last' Strings.
The problem is that, when saved in MongoDB, the 'name' property is not persisted. Though, the other properties, 'accountId', 'added' and 'updated', are persisted correctly.
The effect of 'name' not being persisted is a breakage in the rendering of the contact.html template, that uses 'model.name.first' and 'model.name.last'. As the 'name' property was not persisted, it is 'undefined'.
To correct this issue, I changed the definition of the 'contact' object from above to:
var addContact = function(account, addcontact) {
contact = {
name: {
first: addcontact.name.first,
last: addcontact.name.last
},
accountId: addcontact._id,
added: new Date(),
updated: new Date()
};
Then it worked!
