Node.js Tutorial for Absolute Beginners

This series Node.js tutorial will teach you learn Node.js from Zero to Hero.

What is Node.js?

Node.js is a JavaScript runtime built on Chrome's V8 JavaScript engine.

As an asynchronous event-driven JavaScript runtime, Node.js is designed to build scalable network applications. In the following "hello world" example, many connections can be handled concurrently. Upon each connection, the callback is fired, but if there is no work to be done, Node.js will sleep.

This is in contrast to today's more common concurrency model, in which OS threads are employed. Thread-based networking is relatively inefficient and very difficult to use. Furthermore, users of Node.js are free from worries of dead-locking the process, since there are no locks. Almost no function in Node.js directly performs I/O, so the process never blocks. Because nothing blocks, scalable systems are very reasonable to develop in Node.js.

If some of this language is unfamiliar, there is a full article on Blocking vs. Non-Blocking.

<strong>What is an ORM ? ORM solutions are useful to facilitate data-driven API development. Users have concrete needs which drive the data model of an application. In legacy development, this data architecture is typically implemented and version controlled using database scripts such as SQL scripts. A separate library is then used for the server application to execute CRUD actions on the database.</strong>
