What is NodeJS?
Introduced by Ryan Dahl in 2009, NodeJS is a multi-platform, open-source back-end JavaScript-based execution system built on the V8 engine. It is designed to enable the execution of Javascript codes outside of browsers - hence, developers are able to test scripts server-side, rather than having to do it client-side.
The creation of NodeJS stemmed from the limitation of most web servers back in the day - when thousands of codes had to be processed simultaneously, and code blockages/ executions stacks were not uncommon. Realizing this, Ryan Dahl came up with the idea of a platform with separate "nodes" (modules) to carry out functionalities more efficiently.
With NodeJS, your web/app development project can now be centered around one programming language - instead of having to involve several scripting ones for different steps.
How NodeJS works
The way NodeJS operates is by dividing tasks into different "nodes", thereby reducing the server's workload without sacrificing the ability to run tasks simultaneously. Unlike PHP, NodeJS' functions are non-blocking - in other words, commands are executed asynchronously, and callbacks are used to signal task completion. This eliminates the need for threading.
Although the system is designed mainly to support Javascript, developers may take advantage of source-to-source translators - in order to use the system for other programming languages such as Typescript, CoffeeScript, and Closurescript.
NodeJS comes with modules that support file system I/O, HTTP, DNS, TLS/SSL, binary files, data streams, as well as various other common functions.
Why should I use NodeJS?
Why do I need NodeJS - you may ask. Well, according to a survey by Statista, over 49% of developers said they'd pick NodeJS over other programming systems - and they have good reasons for that.
As more and more users switch from desktop to mobile devices, speed and accessibility become important success factors for webs and apps. One advantage of NodeJS is that it separates different functions (e.g: email, shopping cart...) into "nodes", which allows your system to handle a large number of requests without going down.
What's more, NodeJS is based on Javascript - which has long been the most popular programming language. In other words, your developer team will surely learn how to utilize the technology in no time.
7 Benefits of NodeJS for Developers
For those who are still hesitant, let's take a look at 7 strategic advantages of using NodeJS:
Remarkable speed
NodeJS is fast - due to the fact that it runs on Google’s V8 JavaScript, which operates by compiling JS codes directly into the machine code. As a result, codes are implemented much more efficiently, and multiple input-output requests can be carried out simultaneously without any lagging.
Straightforward operation
As stated above, NodeJS is based on Javascript; hence, your programmer should find the technology really easy to learn and master. Furthermore, as it only requires the use of one programming language, developers may have more time to focus on more difficult tasks such as back-end programming.
Unmatched flexibility
Unlike other runtime environments, NodeJS makes it really simple for developers to make changes to the system. No need to change everything - just focus on the "node" (function) that you are interested in.
Efficient caching
Caching is essential to a website/app's loading speed. One major benefit of NodeJS is its powerful caching ability, which helps store historical data and ensures that all functions may run smoothly.
Amazing scalability
With NodeJS, developers are able to scale apps in both horizontal and vertical directions - by adding more nodes to the current system.
Cross-platform management
Another outstanding feature of NodeJS is its ability to link multiple platforms (e.g: a mobile and a desktop app) together and transfer data between them. Guess what that means? Your developer team now should have their workload reduced significantly.
Easy to get support
Last but not least, NodeJS is known for having a large community of users - many of whom are highly experienced programmers. In case you have any trouble with the system or need to access important resources related to web/app development, somebody out there will be more than happy to assist you!
Who uses NodeJS?
Countless experienced developers have adopted NodeJS to help with back-end programming - without having to switch from JavaScript to another programming language. The system is widely used by a large number of corporations - some of the most notable ones include LinkedIn, Netflix, Trello, Uber, eBay, NASA, Paypal, GoDaddy, Amazon Web Services (AWS), etc.
What is NodeJS used for?
NodeJS helps improve the performance of Javascript-based web servers - thanks to its event-driven programming that employs callbacks to mark finished tasks. As a result, developers are capable of designing scalable servers without needing to resort to threading.
Because of its single-threaded nature, the system is generally recommended for non-blocking, event-driven servers.
Is NodeJS front end or back end?
NodeJS is applicable for both front-end and back-end development. The system comes with various features to support the frontend and backend - including code processor, code linter, module bundlers, network - API calls, data integration, and so on.
