Errata for Learning Node

Not the following command on the page: tar -zxf node-v0.8.2.tar.gz That is followed by the sentence: You now have a directory labeled node-v0.6.18. The version number cited in the sentence is older.

Note from the Author or Editor:
On page 3, 4th paragraph, change reference to node-v0.6.18 to node-v0.8.2.

All occurrences of "windows" should be replaced by "window", the proper name of the global object in a browser environment.

Note from the Author or Editor:
Page 36, the global object is window, not windows. Change.

"usc2" should be replaced by "ucs2".

Note from the Author or Editor:
Page 40, change to ucs2

In the setTimeOut function call, on_openAndReadFile should be the first function argument; there is no openAndReadFile function defined.

Note from the Author or Editor:
In code snippet page 41, correct the last line of code to read setTimeout(on_OpenAndReadFile, 2000, filename, res);

The statement: if (somecriteria) { en.emit('data'); } has 2 typos. To be consistent with the rest of the text, it should be: if (somecriteria) { em.emit('somevent''); } ^^^ ^^^^^^^^^^

Note from the Author or Editor:
Page 59, snippet that reads if (somecriteria) { en.emit('data'); } should read if (somecriteria) { em.emit('event'); }

There appears to be a search missing from the list: * /home/node_modules/mymodule.js The missing search should be inserted between the following two items: * /home/myname/node_modules/mymodule.js * /node_modules/mymodule.js

Note from the Author or Editor:
In list in middle of page 64, insert the line /home/node_modules/mymodule.js between /home/myname/node_modules/mymodule.js /node_modules/mymodule.js

The text says: "Example 5-2 is a complete Node application that creates an object with one method, someMethod", yet in the code example, the method is called "doSomething" not "someMethod".

Note from the Author or Editor:
Change the reference to the literal from someMethod to doSomething on page 83.

Two errors in the process.nextTick example: function asynchFunction = function (data, callback) { process.nextTick(function() { callback(val); }); ); 1. `function asynchFunction` should be `var asynchFunction` 2. `callback(val);` should be `callback(data);`

Note from the Author or Editor:
In this code snippet, which I show in page 39 in Safari Online, change the code from function asynchFunction = function (data, callback) { process.nextTick(function() { callback(val); }); ); To var asynchFunction = function (data, callback) { process.nextTick(function() { callback(data); }); );

"console.log('all finished');" should be changed to "console.log('all done');" to match the output example.

Note from the Author or Editor:
page 88 change the text to all finished in code snippet

The first line of code is: res.setHeader('Content-Type', 'test/html'); It should be "text" not "test": res.setHeader('Content-Type', 'text/html');

Note from the Author or Editor:
Change code snippet from res.setHeader('Content-Type', 'test/html'); to res.setHeader('Content-Type', 'text/html');

You should add the missing closing parentheses at the end of the two app.config() lines.

Note from the Author or Editor:
Add a closing parenthesis to code snippets in sidebar that start with app.config.

You should remove the colon in front of the port number.

Note from the Author or Editor:
Remove the colon in front of the 27017 in the code snippet.

Shouldn't it be true to allow nulls instead of false?

Note from the Author or Editor:
Page 243, section on allowNulls Change to true to allow nulls; true by default

It reads "A form to select which PDF tool to upload" but I think you meant "A form to select which PDF document to upload", didn't you?

Note from the Author or Editor:
Please change text on page 252 from A form to select which PDF tool to upload To A form to select which PDF document to upload

The required colon after the header name is missing. The correct format should be: Content-Range: bytes 44040192-44062881/44062882

Note from the Author or Editor:
Page 266 change snippet of code from Content-Range bytes 44040192-44062881/44062882 To Content-Range: bytes 44040192-44062881/44062882

path.existsSync has been replaced by fs.existsSync not js.existsSync.

Note from the Author or Editor:
Page 299, note, change js.existsSync to fs.existsSync

The technology is named TLS not TSL. You should replace all occurences of TSL with TLS.

Note from the Author or Editor:
Page 316, change TSL to TLS in page.

Database name in USE statement inconsistent with previous USE statement. passport.deserialiseUser() on p328 uses databasenm passport.use() on p329 uses nodetest2

Note from the Author or Editor:
Page 329, code line client.query('USE nodetest2'); should read client.query('USE databasenm');

The content of the name string should be "'johnsmith'; drop table users" with johnsmith properly quoted as it is a string and not a column. Without quoting, the first statement would fail and in some environment (e.g. PHP with PDO), the second statement would not be executed and the attack would be unsuccessful.

Note from the Author or Editor:
Change line to 'johnsmith"; drop table users'
