Node is an exciting new platform developed by Ryan Dahl<\/a>, allowing JavaScript<\/a> developers to create extremely high performance servers by leveraging Google’s V8 JavaScript engine, and asynchronous I\/O<\/a>. In Mastering Node<\/a> we will discover how to write high concurrency web servers, utilizing the CommonJS<\/a> module system, node’s core libraries, third party modules, high level web development and more.<\/p>\n Node.js is a cross-platform, open-source server environment that can run on Windows, Linux, Unix, macOS, and more. Node.js is a back-end JavaScript runtime environment, that runs on the V8 JavaScript Engine, and executes JavaScript code outside a web browser.<\/p>\n Node.js lets developers use JavaScript to write command line tools and for server-side scripting. The functionality of running scripts server-side produces dynamic web page content before the page is sent to the user’s web browser. Consequently, Node.js represents a “JavaScript everywhere” paradigm, unifying web-application development around a single programming language, rather than different languages for server-side and client-side scripts.<\/p>\n Node.js has an event-driven architecture capable of asynchronous I\/O. These design choices aim to optimize throughput and scalability in web applications with many input\/output operations, as well as for real-time Web applications (e.g., real-time communication programs and browser games).<\/p>\n The Node.js distributed development project was previously governed by the Node.js Foundation, and has now merged with the JS Foundation to form the OpenJS Foundation. OpenJS Foundation is facilitated by the Linux Foundation’s Collaborative Projects program.<\/p>\n Corporate users of Node.js software include GoDaddy, Groupon, IBM, LinkedIn, Microsoft, Netflix, PayPal, SAP, Walmart, Yahoo!, and Amazon Web Services.<\/p>\n","protected":false},"excerpt":{"rendered":"
