Overview of this book

Node.js is a modern development stack focused on providing an easy way to build scalable network software. Backed by a growing number of large companies and a rapidly increasing developer base, Node is revolutionizing the way that software is being built today. Powered by Google's V8 engine and built out of C++ modules, this is a JavaScript environment for the enterprise.Mastering Node.js will take the reader deep into this exciting development environment. Beginning with a comprehensive breakdown of its innovative non-blocking evented design, Node's structure is explained in detail, laying out how its blazingly fast I/O performance simplifies the creation of fast servers, scalable architectures, and responsive web applications.Mastering Node.js takes you through a concise yet thorough tour of Node's innovative evented non-blocking design, showing you how to build professional applications with the help of detailed examples.Learn how to integrate your applications with Facebook and Twitter, Amazon and Google, creating social apps and programs reaching thousands of collaborators on the cloud. See how the Express and Path frameworks make the creation of professional web applications painless. Set up one, two, or an entire server cluster with just a few lines of code, ready to scale as soon as you're ready to launch. Move data seamlessly between databases and file systems, between clients, and across network protocols, using a beautifully designed, consistent, and predictable set of tools.Mastering Node.js contains all of the examples and explanations you'll need to build applications in a short amount of time and at a low cost, running on a scale and speed that would have been nearly impossible just a few years ago.

Handling file uploads

It is likely that anyone reading this sentence has had at least one experience with uploading a file from a client to a server. Some may have even implemented a file upload service, a server that will receive and do something useful with a multipart data stream. Within popular development environments this task has been made very easy. In the PHP environment, for example, uploaded data is automatically processed and made globally available, neatly parsed and packaged into an array of files or form field values, without the developer having written a single line of code.

Unfortunately, Node leaves implementation of file upload handling to the developer, a challenging bit of work many developers may be unable to successfully or safely complete.

Fortunately, Felix Geisendorfer created the Formidable module, one of the most important early contributions to the Node project. A widely implemented, enterprise-grade module with extensive test coverage, it not only makes handling...
