What You Need To Know About Node.js


Few would have predicted Node.js in the past, and its success shows that innovation can come from seemingly unlikely places. Although there are plenty of web technologies to consider using, almost all companies looking to serve websites should give strong consideration to Node.js. Here are a few reasons why.

JavaScript on the Server

JavaScript was designed to add a programmatic interface to web browsers, and websites can send JavaScript that the user’s browser will read and run. Node.js, on the other hand, uses JavaScript as the server language, which is then runs to generate websites and perform other tasks. Although it’s not the first JavaScript-based server technology, it came out at a time when the JavaScript language had evolved significantly and many individuals and companies were taking another look at the language. Due to its simplicity and power, JavaScript is now the most popular language in the world by some metrics, and using it as on the server lets companies tap into a large developer base.

Official Package Management

All Node.js installations recommend users install “npm,” which is the official package manager and repository for Node.js. The popularity of Node.js means users can find solutions for a wide range of needs, making the Node.js ecosystem one of the largest and most complete among all programming environments. Npm can also resolve dependency issues, making installing even the most complicated packages simple. It should be noted, however, that npm has no vetting process; users should inspect all packages they use, especially if they’re going to be used in production.

Dynamic but Performant

JavaScript is a dynamic language, and it can’t match the performance of C or other compiled languages. However, Node.js is based on the Google-developed V8 JavaScript engine, which provides excellent performance. Because JavaScript is designed to run within browsers, it’s received far more performance optimizations than any other dynamic language, and these improvements translate to Node.js as well. Furthermore, Node JS performance monitoring tools are mature, and they’re constantly improving. Because Node.js can handle non-blocking asynchronous I/O operations in a graceful manner, it’s an excellent choice for I/O-bound use cases, including web serving.

Web development needs vary significantly, and no single platform is the ideal choice for all uses. However, Node.js has proven to be a flexible, performant and mature option, and it’s a viable choice for a surprising number of scenarios. Companies both large and small should take a look at Node.js when it’s time to choose a server option.
