Node.js: the essence
The core: V8 power
V8 was developed by Google in C++ based on the ECMAScript specification “ECMA-262” and supports the most common operating systems and ARM architectures. The engine can be used completely independently or as an embedded component of a C++ application. V8 is translated into machine code at runtime via a JIT compiler.
Threads v. EVENTS
Conventional server structures usually work thread-based. This means that incoming inquiries are processed sequentially. Requests will only be served once the respective predecessor has been supplied with regard to his request.
In the event-controlled approach, the requests are processed almost in parallel, there is no thread queue, and subsequent requests are not blocked. In this way, a “deadlock” as a worst case is also prevented. Especially for many data-intensive requests on multi-frequency web servers, this circumstance is one of the most significant advantages of Node.js.
Node Package Manager
The “Node Package Manager” provides a variety of ready-made and freely usable packages – so-called modules – for Node.js. These can be conveniently installed via the command line. With these modules, the application radius of Node.js can often be extended many times over.
The “Command Line Interface” represents one of the main input and output interfaces next to the browser window for displaying the web applications running on the Node.js web server. For example, status messages are output, or user input is expected.
Who can use Node.js?
A sensible minimum requirement for the successful use of Node.js consists of a (virtual) server system with underlying root permissions. Finally, a console is sometimes needed, for example, to receive system feedback or to install an npm package.
Top advantages: let’s summarize
Let’s summarize some of the main advantages of Node.js.
- Node.js is an excellent choice for Rest APIs. Rest APIs are used for data exchanges between servers and clients. One of the advantages of Node.js technology is the ability to execute several requests to the server simultaneously because it is a non-blocking “single thread” system. So, Node.js can handle a multitude of requests without waiting for the previously launched request to be completed (we have already mentioned it).
- Excellent performance. With the advantage of processing a multitude of operations in its event loop, Node.js offers incredible performance. In addition, Node.js is lightweight, and the technology is based on Google Chrome’s very powerful V8 engine, which offers incredible performance to web applications that have to search for information and execute a multitude of requests.
- Node.js is very scalable. An application can be decomposed, so it is possible to quickly add a new architecture without affecting all your services. This facilitates updates and possible evolutions on your web application.
