JavaScript is the most popular and exciting programming language. Decades have passed, but advancement has always succeeded us all in providing the best possible tech stacks. Libraries, frameworks, and technologies are excellent in developing a successful web venture.
Vue, Angular, Next.js, Nodejs, Reactjs, and others are among the top ones to achieve great stature in the tech world. But out of all these advances, Node has made a remarkable journey in providing the best web app development services.
According to a recent survey as of July 2023, there is a commendable increase in the use and traffic of Nodejs, i.e. it is witnessed as one of the popular web servers.
Backend technology has gained only some of this skyrocketing popularity overnight. It has been constantly updating itself year after year. The latest version of Node is Nodejs 20, which has again brought a lot of curiosity among software developers.
There are over 6.3 million websites that are using Node, and it is very much popular among the U.S.A. web app developers. A user majorly approaches the advancement to build eCommerce, IoT, crowdfunding, or payment processing apps. It works well on Windows, Linux, Unix, Mac OS X, etc. And also, it has many other great benefits, which we will discuss in the blog later.
Now, let’s quickly dive into the definition of Nodejs and get all our facts straight before moving deep into its services and benefits.
What is Nodejs?
Node is not a programming language or a framework, or a library. It is defined as a JavaScript runtime built on Chrome’s V8 engine. Nodejs is also written in C, C++, and JavaScript.
In 2009, Ryan Dahl, the developer of Node, released his very dear innovation to us. Due to the major drawbacks of Apache HTTP, the world got a new JS tech. The goal behind the development of Node was to overcome all the issues related to Apache.
The advancement offers great scalability with parallel code execution. It also introduced new logic and different approaches toward JavaScript server-side development. Also, the digital revolution introduced a single-threaded event loop model to perform all requests simultaneously. Thus, it has ensured to turn every unturned aspect of a web app solution.
Core advantages of Nodejs development
There are many Nodejs development benefits, and we will discuss them in detail, but some are listed below.
- It facilitates speedy executions with a V8 engine.
- Node Package Manager (npm) provides over 50,000 package bundles.
- It is asynchronous.
- It has a large community of active experts.
- The advancement is easy to learn.
- Conventional websites and backend API services are well-created using Nodejs.
Now, come to the technical part of its architecture and the core functioning. Let’s have a look at it.
How does Nodejs architecture function?
When creating an online business requiring constant requests, let’s say, an eCommerce website where the users are constantly sending requests for items, placing orders, and browsing through the solution.
To handle multiple clients, Node successfully uses single-threaded event loop architecture. Now, what is so different than other runtimes? In a multiple-threaded request model, multiple clients send a request, and the server responds to a request after processing each one. However, multiple threads are used to process callbacks. All the threads are defined in a thread pool, and for every request, a specific thread is assigned to look at it.
Nodejs works differently.
- It manages a very limited thread pool for server requests.
- A request received is put in a queue.
- The renowned feature’ event loop’ plays an important role at this point. It waits for requests indefinitely.
- When a request is received, the loop checks from the queue whether a blocking input/output (I/O) action is needed or not. If not, then it proceeds forward by responding to the request.
- The event loop selects a thread from the internal thread pool to continue with the process of other requests
- The event loop monitors blocking requests and add them to the queue. It keeps a non-blocking functioning of the whole solution.
Thus, Node uses fewer threads, which results in less memory generation, helping in faster task execution. So, it fulfills all the requirements and is equivalent to providing services of a multi-threaded architecture. This JS popular is the best choice for an app that has to run in real-time and has to undergo changes & updates with digital inventions.
After looking at the whole architecture, you are pretty much clear on its scalability and robustness. Let’s quickly dive into some more advantages of Nodejs that are welcomed by developers across the globe.
Why is Nodejs popular among developers?
Nodejs development works best for developers as it provides new yearly updates. And Node is very easy to execute, learn, and develop a solution with its services. Let’s look into some of them.
Easy to learn: As it is a JavaScript advancement, it is easy to learn. JS has been around for a while and has a huge community to help with any query. So, learning Node is just a matter of a few weeks. And for someone unaware of JS, it might take a little longer, but it is pretty much easy to understand.
Scalability and fast speed: Nodejs handles concurrent requests at a time. The major reason for its popularity is this particular functionality. It handles all the requests without overstraining a server. A callback takes place only after a request is made. And so, the tech is not a hindrance in any other functionality. It also helps avoid the usage of RAM.
Also, with the help of the V8 engine, it performs every task on time with speed and proper execution. The asynchronous and single-thread event loop plays a pivotal role in making it a speedy JS runtime environment. Thus, reading/writing a file system, network connection, or database execution is done easily with Nodejs. The experts get the upper hand in developing agile and highly scalable apps that can handle bulk requests.
Mobile-friendly & lightweight: It has cross-platform abilities to perform smoothly across Linux, Windows, or Mac OS. Such flexibility helps Node to be a mobile-friendly tech tool. And also allows developers to write apps that run on varied platforms with slight modifications.
Node is a single-thread web technology that allows quick client requests. It reduces the coding and lays a foundation for non-blocking I/O features. And this is a lightweight advancement because of the V8 engine and non-blocking models.
Cloud-based hosting providers: Many cloud-based hosting providers and web servers facilitate Nodejs. Heroku, AWS, Digital Ocean, Google, Microsoft IIS, etc., are among them. So, it is easy to host Nodejs from anywhere.
Easy to modify & maintain: Nodejs always adapt with time. And, with it comes many perks that allow a developer to modify and maintain its solution easily. Node makes small and big apps at ease and provides great new functionalities. The code base is ever-evolving with other surrounding tech changes. Thus, one learns and implements in real-time with Nodejs app development services.
Ability to cache: It is indeed popular for its caching abilities. Caching deals with the storage of data for future requests. With Node, the request made is fetched from the cache instead of the main server. And so, the solution made by the tech loads faster and responds quicker than other tech stacks.
These are some of Node’s benefits or functionalities that make it popular among developers. Before ending the blog, let us serve you with the last piece of information, a very important one related to NOde. Of course, you must know about it, but we will like to remind you about it for once.
What apps can you extensively create with Node.js?
One can make all kinds of apps with Node. Below are some exceptions you can make with the JS popular.
- Single-page apps like Portfolio
- Social media apps like LinkedIn
- Real-time apps like Whatsapp
- Streaming solutions like Netflix
- an eCommerce platform like Walmart
- Blog apps or sites
- Mobile apps as it is easily able to work with frameworks like Express and others.
On a concluding note
node js development service is the best resource for a JavaScript-backed online venture. You will get all the necessary software development services for your project in this runtime environment. From a single-threaded event loop to a V8 engine, it provides extensively scalable and easy-to-manage architecture.
Now, you know why it is the most loved digital advancement to date. Rope into it and develop a great software solution for your business. Invade the online space with the right set of teams and an evolving tech stack like Nodejs development.
