Besides the long-standing emergence of programming platforms like JVM (Java Virtual Machine) or .NET, NodeJS is known as a new member yet has brought a new wave to the Software Development field. Nowadays, you can see web applications developed from Node JS-based anywhere, from server-side web applications to end-user desktop applications, or internet applications, etc.
With abundant outstanding advantages, NodeJS has become one of the very popular programming platforms and is trusted by many experts, even not inferior to the previous platforms. This article will briefly introduce you to the Node JS platform, some of its roles in software development, as well as listing top NodeJS development companies in Vietnam.
What is NodeJS?
NodeJS was written by Ryan Dahl in 2009 and has been sponsored by Joyent Company, based in California, USA. The initial release was developed to support only Linux and Mac OS X, a later build was added to support Windows in 2011. The Node JS is a server-side platform built upon the JavaScript Engine (V8 Engine).
NodeJS is defined by official documentation as follows: “The NodeJS platform is based on the Chrome JavaScript runtime to build fast, large applications. NodeJS uses event-driven components, non-blocking I / O models to create lightweight and efficient applications for real-time data applications running on dispersing devices."
You can roughly understand that NodeJS is a platform (an environment) used to build web applications, network applications, tools, libraries, ... It can be considered as a set of tools, frameworks, libraries, capabilities, and programming languages that use to help you build an application.
The core part of NodeJS is that it is written in C++ language, so it offers very high processing speed and performance, suitable for applications with large traffic volume, applications that need to expand or innovate technology, or quickly create effective new projects. NodeJS also provides us with various JavaScript modules that simplify the development of applications and extensions.
Since NodeJS is not a traditional programming language, but a runtime environment, it is easy to learn for both Front End and Back End developers. Node JS Back-end developers, in particular, can benefit from the efficiency, high speed, and high performance of Node JS, with the utilities such as code sharing, and the addition of free tools such as tracking and debugging.
When referring to NodeJS, we must immediately think of the concept “Realtime”. Realtime here is real-time processing of client-to-server communication. This can be explained as when you surf today's social networking sites (Facebook, Twitter, Instagram, ...), every time you comment or like a certain topic, the host and the people who commented on it immediately receive a new notification.
What is the role of NodeJS in software development?
Currently, there are many websites using Node Js platform to program their own websites, such as LinkedIn, Walmart, NASA, Netflix, eBay, Paypal, ... This proves the prestige and the quality of the Node JS platform has contributed significantly to the expansion of web applications.
Because of using a popular programming language, but with incredible performance and task processing speed, and real-time, Node JS is extremely popular with programmers. Let's take a look at the highlights of Node JS in software development today!
1. Asynchronous and event-driven: All NodeJS APIs are non-blocking. Basically, that means that the Node JS-based server never waits for the API to return data. The server switches to the next API after calling it, and the NodeJS Event notification mechanism helps the server get the response from the previous API call (Real-time).
2. Very fast: Built on the V8 JavaScript engine of Google Chrome, the NodeJS library is very fast at executing code.
3. Single-Threaded & Highly Scalable: NodeJS uses a single-threaded model with event loops. The event mechanism helps the server respond in a non-blocking manner and makes the server highly scalable compared to traditional servers that generate limited streams to process requests. Node JS uses a single-threaded program and the same program can serve a much larger number of requests than traditional servers like the Apache HTTP Server.
4. No Buffering: NodeJS applications never buffer any data. These applications simply export the data in the block.
5. License: NodeJS is released under the MIT license.
Advantages of using the NodeJS platform:
Due to using JavaScript - a popular language used by most developers. Hence, programmers do not need to learn any other programming languages, save time and still bring high efficiency. In addition, the synchronous use of a programming language helps team members work more closely and easily detect errors and correct them even when there is technology transferring.
NodeJS is run on the basis of HTML and JavaScript programming languages, these 2 languages have a consistent and flexible synchronization, so there is no need to use a third-party application to communicate between the server - the client in real-time execution.
Thanks to asynchronous event navigation and logger techniques that help handle many different connections, server sequencing is easier.
Disadvantages of NodeJs
NodeJs is a single thread processing platform, so for image, video... applications that need more information processing resources, it will be difficult for Node JS to perform tasks related to images, videos, graphics…
NodeJs is a recently developed platform, so there is no strict module censorship system because in fact there are too many free modules, not quality assurance on the market, which partly affects the quality of the application based on the NodeJS platform.
But we can fully believe that NodeJs is still on the rise and over time NodeJS will have certain features to change to become more up-to-date and more optimized to meet all demands and overcome current limitations.
Why is Vietnam an ideal destination for NodeJS projects?
