Traditional, multithreaded web servers are usually scaled only when the resources assigned to a machine cannot be upgraded any more or when doing so would involve a higher cost than simply launching another machine. By using multiple threads, traditional web servers can take advantage of all the processing power of a server, using all the available processors and memory. However, with a single Node.js process it is harder to do that, being single-threaded and having by default a memory limit of 1.7 GB on 64-bit machines (which needs a special command-line option called --max_old_space_size
to be increased). This means that Node.js applications are usually scaled much sooner compared to traditional web servers, even in the context of a single machine, to be able to take advantage of all its resources.

Overview of this book
Node.js is a massively popular software platform that lets you use JavaScript to easily create scalable server-side applications. It allows you to create efficient code, enabling a more sustainable way of writing software made of only one language across the full stack, along with extreme levels of reusability, pragmatism, simplicity, and collaboration. Node.js is revolutionizing the web and the way people and companies create their software.
In this book, we will take you on a journey across various ideas and components, and the challenges you would commonly encounter while designing and developing software using the Node.js platform. You will also discover the "Node.js way" of dealing with design and coding decisions.
The book kicks off by exploring the basics of Node.js describing it's asynchronous single-threaded architecture and the main design patterns. It then shows you how to master the asynchronous control flow patterns,and the stream component and it culminates into a detailed list of Node.js implementations of the most common design patterns as well as some specific design patterns that are exclusive to the Node.js world.Lastly, it dives into more
advanced concepts such as Universal Javascript,
and scalability' and it's meant to conclude the journey by giving the reader all the necessary concepts to be able to build an enterprise grade application using Node.js.
