Formidable seems to have changed slightly since the book was written it seems that the files. I know how frustrating such a problem can be for a complete beginner, so here's my Stackoverflow answer addressing the problem. Hopefully that helps somebody.

The book was my first encounter with functional programming paradigm and although it wasn't sufficient for me to learn it appropriately, it worked as an introduction which prepared me to go for intermediate books about the topic.
Too much text compared to the amount of information about node. The author promised a full application at the end of the book, but instead of giving at least one example of some kind of test for his code, he explains what a router or request handler is for. Good to know other books about node, because from them I know mocha, should, and assertions.
No one example in this book. That reminds me to all this shitty "write your blog in 5 minu The author should write poetry instead of technical books. That reminds me to all this shitty "write your blog in 5 minutes" rails tutorials around the web. View all 3 comments. Aug 14, Randell Benavidez rated it it was amazing Shelves: This book is a good introduction to Node.
It also walks the reader through creating a very basic web application that allows the user to upload a PNG image. Very nice overview of Node. For someone with some experience with JS, and with other backend languages, this book was perhaps slightly oversimplified, but it has still given me a basic understanding of the concepts needed. While it hasn't prepared me to make my own applications, it has brought my level up to a point where a fully sized Node.
You can sit and read this book in a day, and I think it accomplishes exactly the goal it is trying to. Oct 29, James Martin rated it it was amazing. A clear, simple, useful introduction to Node. As Kiessling's development background i. PHP matches my own, the tutorial was perfect for me. I'm not on to his sequel, The Node Craftsman Book. Aug 02, Jerry rated it liked it. It's a pretty decent and useful book, but I feel it is a little bit too short.
Most importantly, it introduced http module, which is fine; but it did not mention express at all. I wasted some time on http module for not knowing the existence of express.
I'd suggest the author mention that there is a high-level module named express before starting on any low level modules. Dec 06, Dustin rated it liked it Shelves: This is a solid couple of hour crash course for generic Node. The author did an alright job showing how blocking works, how to think about callbacks in general, and some of the features. The book reminds me some of Learn X the Hard Way without enough exercises.
I'd recommend this book if you have absolutely no experience with Node. If you have a general grasp on blocking, callbacks, npm, require, and exports then you might be able to skip this.
While the book doesn't go into any g This is a solid couple of hour crash course for generic Node. While the book doesn't go into any great detail on any of those subjects, if you don't feel comfortable with any of them then this might be a good refresher at the least. This isn't a book I'll reference often if at all but it is something I'd recommend to someone that's never touched node.
The author has done a good job of keeping the book and examples up to date everything still works in v0. May 18, Benjamin rated it liked it. It was an okay introduction. Fairly easy to get through. I think I had an older version and wish mine was more up to date.
I like the way the author writes, and his examples are pretty clear to follow. Good for an absolute beginner like me to get interested in Node, but doesn't go into a whole lot of detail. HOWE It was an okay introduction. I don't get it. Oct 31, Pete rated it really liked it Shelves: It's 50 pages that provides a short, quick digestible tutorial in writing node.
The book is aimed at people who can program and want a quick introduction to node. After a hello world in Node routing, callbacks and how node work are described. Finally an application that allows text input and file upload is deve The Node Beginner Book by Manuel Kiessling is a book and tutorial that describes how Node. Finally an application that allows text input and file upload is developed.
It worked well for me. It's also part of a package with a second book that concludes with a description of writing an application with AngularJS and node together.
Thus, Node. In order to make use of these, you need to install Node. Instead of repeating the process here, I kindly ask you to visit the official installation page.
Please come back once you are up and running. Ok, let's just jump in the cold water and write our first Node. Open your favorite editor and create a file called helloworld. Ok, this stuff is boring, right? Let's write some real stuff. Fair enough. Now, you could achieve this goal by googling and hacking together something.
But that's not what we want to do here. Furthermore, we don't want to write only the most basic code to achieve the goal, however elegant and correct this code might be. We will intentionally add more abstraction than necessary in order to get a feeling for building more complex Node.
Let's dissect our application. Which parts need to be implemented in order to fulfill the use cases? Let's think a moment about how we would build this stack with PHP. Which in turn means that the whole "we need to be able to serve web pages and receive HTTP requests" stuff doesn't happen within PHP itself.
Well, with node, things are a bit different. Because with Node. In fact, our web application and its web server are basically the same. This might sound like a lot of work, but we will see in a moment that with Node. Let's just start at the beginning and implement the first part of our stack, the HTTP server.
When I arrived at the point where I wanted to start with my first "real" Node. Do I need to have everything in one file? What if I want to make sure that my code stays readable the more stuff I implement? Turns out, it's relatively easy to keep the different concerns of your code separated, by putting them in modules.
This allows you to have a clean main file, which you execute with Node. So, let's create a main file which we use to start our application, and a module file where our HTTP server code lives. My impression is that it's more or less a standard to name your main file index. It makes sense to put our server module into a file named server. Let's start with the server module. Create the file server. That's it! Building the application stack 43 function error.
But how can we achieve our goal. Which is why the callback is called relatively expeditious. To be more precise. Our new approach is as follows: Dangerous stuff.
Enough explanation. But one possible solution for this is. Quite often. Right now. Instead of expecting a return value from the route function. Next comes router. If no request handler can be used.
Building the application stack 46 function route handle. Same pattern: And last but not least. The start handler will respond from within the anonymous exec callback. If we start our application again node index.
Our handler functions need to accept the response parameter. This will make HTTP requests to http: For the sake of simplicity we will assume that only image files are going to be uploaded and displayed through the application. Our server. Building the application stack 49 Serving something useful Until now.
We will first look at how to handle incoming POST requests but not file uploads. This author likes to hear himself talking way too much anyways. Upon receiving and handling this request. We will present a textarea that can be filled by the user and submitted to the server in a POST request. You should see this very simple form when requesting http: Now that we are becoming expert novices. If not.
I decided to not include that extra level of abstraction i. Which makes sense. I hear you: This is done by adding listeners to the request object that is passed to our onRequest callback whenever an HTTP request is received. This basically looks like this: Building the application stack 52 multiple megabytes in size.
To make the whole process non-blocking. We currently can access the request object in our server only. We need to tell Node. Handling the whole bulk of data in one go would result in a blocking operation.
These events are data an new chunk of POST data arrives and end all chunks have been received. I suggest we handle the POST data processing right in the server and pass the final data on to the router and the request handlers. The question arises where to implement this logic. In my opinion. Building the application stack 53 Thus. Here we go. Put small amounts of text into the textarea as well as lots of text. Adding the console logging on every chunk that is received probably is a bad idea for production code megabytes of POST data.
We basically did three things here: I suggest playing around with this a bit. We also pass the POST data into the router. Building the application stack 54 http. Building the application stack 55 function route handle. And in requestHandlers. We already read about the querystring module.
We will probably want to consume the individual fields that make up the POST data. One last thing for this topic: It allows us to install external Node. At the end of the day. Given a working Node. The external module we are going to use is node-formidable by Felix Geisendoerfer. Our plan was to allow users to upload an image file.
Building the application stack 58 exports. It nicely abstracts away all the nasty details of parsing incoming file data. The formidable module is now available to our own code. The example code from the node-formidable project page shows how the different parts play together: Building the application stack 59 npm install formidable on our command line.
If the following output ends with npm info build Success: All we need to do is create a new IncomingForm. If we put this code into a file and execute it through node. It of. Building the application stack 61 the form. We are obviously going to read the contents of this file into our Node. Building the application stack 62 course makes a lot of sense to save a real png image file to this location first.
We are going to modify requestHandlers. Building the application stack 63 response. By restarting the server and opening http: Step 1 is simple. The next step is a bit more complex of course. There may be more elegant solutions. The first problem is: Sad panda. Looks like we will have to pass the request object all the way from the server to the router to the request handler.
But all we have is the response object and the postData array. Building the application stack 67 And while we are at it. There is a bit of extra-complexity in the rename logic: Building the application stack 68 function route handle. Building the application stack 70 form. Restart the server. Select a local PNG image from your hardrive. Conclusion and outlook Congratulations. The Node.
