The fact that Node.js is open source means that it is free to use and constantly being tweaked and improved by a global community of developers.Īn important thing to understand about Node.js is that it is actually neither a framework or a library - as with traditional application software -, but a runtime environment.Ī runtime environment (sometimes shortened to RTE) contains Web API’s that a developer can access to build a code, and a JavaScript engine that parses that code. In simple terms, what this means is that entire sites can be run using a unified ‘stack’, which makes development and maintenance quick and easy, allowing you to focus on meeting the business goals of the project.

Every browser has its own version of a JS engine, and node.js is built on Google Chrome’s V8 JavaScript engine. It is used for server-side programming, and primarily deployed for non-blocking, event-driven servers, such as traditional web sites and back-end API services, but was originally designed with real-time, push-based architectures in mind. Node.js is an open source, cross-platform runtime environment and library that is used for running web applications outside the client’s browser.
