It is a known fact that Node.js can be used to develop a wide range of applications. Node.js is a cross-platform and mobile-friendly scripting language. With the capacity to manage multiple requests simultaneously, it is well known for fast code execution, making it the most sought-after among developers.
Node.js has a strong community and bug tracking team, having its own modules and tools that are easily available on Node Package Manager (NPM).
Here’s an elaboration of some of the benefits of Node.js.
Thus, reading/writing to file systems, network connections and to the database is executed quickly in Node.js. It allows Node.js developers to build agile and highly scalable network applications that are capable of handling bulk amounts of simultaneous connections having high throughput.
Node.js uses a basic event-driven architecture. This means everything executed on it, including every single operation and call, is a series of asynchronous callbacks. This enables Node.js to run on a single thread as unlike other web technologies where a new thread is spawned for every client request. This not only makes it light in weight, but also forms the foundation of Node’s non-blocking I/O feature.
While Node.js is gaining popularity among users in recent years, there are several cloud-based hosting providers and web servers that support web applications built on Node out-of-the-box. This includes Google, Amazon AWS, Heroku, Microsoft IIS, Microsoft Azure and more.
The problem that crops up with traditionally built applications is that they become less adaptive and rigid over time. Eventually, they start creaking under the stress they were not built for. However, developing new services using Node.js is comparatively easier. With Node.js, a bunch of small applications are built instead of a single, large application. This allows making changes or adding a new functionality with much ease, without having to make changes deep inside the code-base.
Node.js is designed with scalable network applications in mind. Node.js can handle many concurrent requests. This is the main reason it quickly became popular among developers and large companies. It can handle multiple requests simultaneously without straining the server. A callback is fired only after a request, but if there are no more jobs to be done, Node.js will go to sleep. Node.js is only online when needed. This avoids unnecessary usage of your RAM.
The ability to build flexible apps that run smoothly on any platform – Linux, Windows or Mac OS – gives Node.js a big thumbs up. There has been a rise in cross-platform app development in the last few years. The fear of apps not running on other operating systems is overcome by Node.js.
Node.js web development does not provide everything that you need all at once. Instead, you customise or add what you need over time. This prevents having unnecessary libraries. Npm - Node package manager is the default package manager in Node.js.
