And, for the backend development, programmers suggest using Node js – a cross-platform and open-source environment. In fact, this technology has become extremely popular over the last few years and, thanks to its characteristics, will continue to stand the competition in 2022 for many startups and enterprises.
In this guide, we’ll make a detailed overview of what is Node.js, its pros, and cons, yet explain the major features that will surely come in handy for you and your business.
What Is Node.js & How Does It Work?
In other words, that’s not either a framework, programming language, or library, which is used for the traditional application software, Node.js is an environment for them.
Nowadays, Node.js is already been widely used for front-end and back-end API services development, encompassing:
Traditional web sites
Single-page applications (SPA) development
IoT app development
Social media networking (back-end development)
The Specific Features of Node.js to Know
Once you’ve reviewed the basic information about Node.js, it’s time to learn more about its potential – by reviewing the main features of this environment. This will help you to get a better idea of using Node.js, yet helps to evaluate whether or not it’s the right option you need for the software development projects.
Some of the useful functions of Node.js you should certainly pay attention to include:
Microservices – an individual, self-contained unit that works alongside others to make up a large application. They allow different app components to be compartmentalized and managed individually, modified, and updated without impacting the application performance.
Event-driven programming – a feature that allows getting a quick response to various forms of user engagement, including clicks or key presses. This feature is designed to detect actions once they occur to reach a more reactive and intuitive UX, and add more to the app flexibility.
However, there are 3 major features of Node.js, which helped it to gain that much popularity, and which we should certainly review in detail: Non-blocking I/O, Libuv, and Node Package Manager.
This feature is developed to avoid the issue of the synchronous thread (also known as the separate threads) – the situation in which a separate thread is started for each request and blocks the entire process.
Commonly, many environments help web servers to start individual threads, but Node.js allows working with single threads in turns.
Libuv is the specific cross-platform C library that is mainly designed for Node.js environments and ensures the constant processing of the single threads with the mechanism known as an event loop.
Node Package Manager (NPM)
Also called NPM, note package manager is in-built support for package management, that includes hundreds of thousands of downloadable libraries for any specific preferences and needs. NPM is mainly known as the world’s largest software registry, which is absolutely free for use and is getting larger day by day, which greatly empowers the Node.js community.
Some of the most useful NPM modules today include:
With these modules applied, you can more than surely create a powerful module that features a high performance, automates time-consuming tasks, ensures robust routing, and provides top-notch test coverage.
What Are the Advantages of Node.js Use?
Another essential aspect we should shed light on in the comprehensive guide to Node.js is the upsides and drawbacks of this environment. In this case, you’ll be more than surprised by the lucrative benefits of using Node js.
First of all, the apps based on Node.js are easily scalable, both vertically and horizontal. Vertical scaling enables adding more resources to the current nodes, while horizontal – allows adding new nodes quicker, which can greatly speed up the development process. Additionally, the Node.js apps can perfectly work with a set of microservices and modules, which makes the development process more simple and easy – a perfect option for scalable startups.
Large Node.js Community Support
Along with the millions of fans contributing to support developers across the globe, the Node.js Foundation, which was established in 2015, consists of leading enterprises such as IBM, Microsoft, Fidelity, and SAP. This means you’ll always find support among semi-minders, as well as develop and maintain any framework created.
Among many developers, Node.js is known as the powerful, feature-rich environment for developing ultra-fast-performing and scalable apps. With the event-driven architecture and non-blocking I/O tasks that can easily run on a single thread, without blocking any operations and with almost no delays. These characteristics make Node.js a resource-efficient tool that can greatly accelerate the framework speed.
Advanced Development Speed
What is more, one of the best features of Node.js use is its ability to accelerate the web app development process with a variety of tools that are lightweight and easy to use. The NPM registry provides a wide range of solutions, modules, and libraries that enable the creation of more valuable apps at a lesser effort and cost. What is more, this environment helps to significantly reduce the bugs, decrease the app size and develop the app in short time frames with the reusable template.
More Flexible for the Various Software Development
For most developers, Node.js is a perfect environment for developing cross-platform apps. With frameworks like Electron, NW.js, you can now launch top-notch applications that are fully compatible with nearly any device on macOS, Windows, or Linux.
In addition to that, Node.js supports the MQTT protocol, commonly used by IoT applications, making it easy to connect to independent and third-party services, as well as prepare them for the back-end integration through different environments.
When It’s Better to Avoid Node.js?
Nearly any technology today has its pros and cons, so before you start using any of those, you should ensure it’ll work best for your project. With all its benefits incorporated, there are still some cases when Node.js is not the best option to choose for the software development process.
You might encounter the other tech solutions in the following cases:
Creating a perfect software solution. Despite the NPM modules and libraries included, the apps created with Node.js can still have bugs and poor quality in cases when the developers don’t have enough experience with using this system.
For CPU-intensive computations. It’s better to avoid using Node js if the app server deals with heavy computations, it gets blocked because of the single-threaded quality of Node.js.
Launching a server-side web app with a relational database. If a server-side web app has any CPU-intensive computation, it is likely to block Node.js responsiveness. Because the Relational Database is still underdeveloped, it’s better to consider the other environments to perform related functions.
Heavy server-side processing. Due to its event-driven and non-blocking I/O node models, Node.js can block the incoming requests while the threads are working on computing processes.
Successful Examples of Implementation & Future of Node.js
To evaluate the future potential of Node.js, nothing works better than uncovering the successful use cases of this environment and the ways of its possible implementation in different industries. In the case of the Node.js environment, plenty of companies from various industries have already switched to this technology, for instance, Amazon, eBay, Netflix, Reddit, AliExpress, Paypal, and many more.
So, to define how to use Node.js effectively, let’s review some of these cases more closely:
Because most users interacted with the network through mobile devices, in 2016 LinkedIn decided to switch to Node.js. As a result, the company has boosted its performance by nearly 20x times, empowered servers and reduced their amount from 30 to 3, and drawn its focus on app development and improvement instead of troubleshooting.
Being one of the first companies that started using the Node.js environment in the full production stage, Uber managed to reach a productive, scalable, bug-free app that works perfectly on macOS and Android devices. This tech solution helped them not only to process billions of requests every day but also to match multiple riders to drivers in fractions of seconds.
After implementing Node.js, Netflix has finally found a scalable solution that can process multiple requests of their users simultaneously. At the same time, they managed to use the same language for front-end and back-end processes, thus significantly saving up the startup time from 40 minutes to less than 60 seconds.
As you can see, with more than 50% of the developers using Node js in their projects over the last few years, we can make a conclusion that this tech environment will only continue to rise in 2022.
To sum up, Node.js is one of the leading technologies for app development today, that allows you to effectively create a first-class application for nearly any industry. After you’ve learned what is Node.js used for, defined its benefits and possible drawbacks, it becomes easier to understand whether or not this environment is the right option for you and your business.
