Node.js
Javascript run time that is new and updated
Node.js is a popular framework whose syntax is based on the JavaScript (JS) programming language. The main purpose of this platform is to develop scalable distributed web projects and applications with high performance. With this component you can create chat rooms with multiple simultaneous connections and even online games. Before installing the "node", it is worth learning the syntax and basics of JS.
The installation kit includes REPL (JS launcher), package manager (npm) and a set of modules. However, most of the time you will have to use the standard command line - cmd.exe. Or you can use a web platform from Microsoft and their WebMatrix application or other stable IDE environment (like PhpStorm or IntelliJ IDEA). Some programmers also prefer to work with the "node" in Cygwin, as the framework was originally developed for Linux and MacOS, and later appeared a stable version for Windows.
One main benefit of using Node.js is its ability to create highly scalable, performance-oriented web applications with efficient memory usage under heavy loads.
The platform concept is based on the work of independent modules. This means that all classes, functions and variables declared through var cannot be used in one file in another, as they are not initially displayed in global space. However, data from different modules can be exported via module.exports or loaded via global objects.
The popularity of the framework is related to the event-oriented approach instead of the threading system. And if JS is most often used to create the client side of the site, then Node.js - to develop the server part with high memory consumption under high load.
- flexible development with JavaScript;
- asynchronous programming;
- support for a large number of simultaneous connections to the server;
- runs on the V8 engine, which is also used in Google Chrome;
- using an event-driven paradigm;
- any third-party programmer can write their own module;
- a large community on stackoverflow and other web resources.
PROS
Excellent for real-time applications like chat and gaming apps.
Rich ecosystem of open-source libraries available.
CONS
Computationally heavy tasks can slow performance.
Not ideal for relational databases.
Arran
Node.js as an element used for backend programming. While other technologies in the stack are optional and can be replaced with alternatives , Node.js stands out for its handling of web tasks. It utilizes the V8 engine originally created for the Chrome browser to compile JavaScript functions into machine code swiftly. What sets Node.js apart is its ability to handle requests efficiently through blocking Input/Output and asynchronous request handling, thus it enhances its overall performance. This scalability also proves beneficial in microservices architecture due to Node.js lightweight nature. By breaking down application logic into modules microservices offer flexibility, Pave the way for future expansion enabling easier addition of new services. Prominent companies like PayPal have experienced improvements in response time after transitioning to Node.js highlighting its effectiveness, in real world scenarios. In summary Full Stack JavaScript, centered around Node.js provides an scalable solution that meets web development needs.
