Today's web demands efficient real-time applications and scalability. Asynchronous event-driven programming is ideal for this, and this is. DaviD Klein.

If nothing happens, download GitHub Desktop and try again. If nothing happens, download Xcode and try again. If nothing happens, download the GitHub extension for Visual Studio and try again. Some labels can be applied in parallel.

This leads to rapid, fluid development cycles. The full-stack, single language experience means less context-switching between languages for developers, architects and whole teams. This book shows you how to build fast, efficient, and scalable client-server solutions using the latest versions of Node.
The book begins with debugging tips and tricks of the trade, and how to write your own modules.
Then you'll learn the fundamentals of streams in Node. We also cover the options for building web application with Express, Hapi and Koa. You will then learn about security essentials in Node. By the end of the book you will have acquired the level of expertise to build production-ready and scalable Node.
He assists multinationals and start-ups alike with architecture planning, creating and leading development teams, innovation projects, internal evangelism, training, and deep dive consultancy on all aspects of live systems architecture, performance, infrastructure, and deployment.
Mathias likes to work with P2P and distributed systems, and he is the author of more than modules on npm, including some of the most popular ones for working with streams. In addition, he has spoken about mad science projects at various conferences around the world.
Matteo Collina is principal architect at nearForm. Matteo is the author and maintainer of more than Node. Some of his modules are the most performant, and he is an acknowledged Node. He has spoken at over 50 international conferences, including NodeConf.
He is also a member of the Node. Formerly a physicist working on the JET nuclear fusion research project, Peter has worked across several industry verticals, including disaster recovery, telecommunications, and social media.
Peter has been the cofounder and CTO of two companies prior to nearForm, and he holds degrees in theoretical physics and computer science. Based in Ireland, Peter spends his time consulting for clients, working on open source software, writing, and conference speaking.

This is what Node. Plus, Node. 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. Open your favorite editor and create a file called helloworld. Ok, this stuff is boring, right?
Let's write some real stuff. A full blown web application with Node. 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. The application stack Let's dissect our application. Which parts need to be implemented in order to fulfill the use cases?
We want to serve web pages, therefore we need an HTTP server Our server will need to answer differently to requests, depending on which URL the request was asking for, thus we need some kind of router in order to map requests to request handlers To fulfill the requests that arrived at the server and have been routed using the router, we need actual request handlers The router probably should also treat any incoming POST data and give it to the request handlers in a convenient form, thus we need request data handling We not only want to handle requests for URLs, we also want to display content when these URLs are requested, which means we need some kind of view logic the request handlers can use in order to send content to the user's browser Last but not least, the user will be able to upload images, so we are going to need some kind of upload handling which takes care of the details Let's think a moment about how we would build this stack with PHP.
