When it comes to understanding Node.js’ pros and cons for your web application , there are several factors a developer has to consider. For example, tech scalability, speed, performance, application limitations, and much more. So how fast your application will reach the market depends on decisions made at this stage.
Node.js is an open-source platform as well, which increases flexibility that helps in building real-time network applications. It offers the developers asynchronous, event-driven I/O APIs. It runs on a single-threaded event-based loop, so all executions become non-blocking.
Node is a popular platform for building full-blown Node.js web applications, hybrid applications, REST APIs, desktop programs, and even IoT solutions. Using Node.js for server-side programming has both advantages and disadvantages.
Let’s understand the pros and cons of node js to match your requirements and make a balanced choice.
One of the essential advantages of node.js is that you can build super boosted applications that give results in the blink of an eye.
Web applications powered by Node.js benefit hugely from its capability to multitask. Its single-threaded, event-driven architecture processes multiple parallel requests efficiently without jamming the RAM. Also, its event-loop and non-blocking I/O operations let code execution at a pace that indirectly affects the application’s overall performance.
Node.js helped GoDaddy beat its competition. During the SuperBowl ad campaign, the web hosting company GoDaddy handled 10,000 requests per second absolutely without downtime by utilizing only 10% hardware.
Moreover, the run-time environment also increases the code execution speed as it supports the non-blocking I/O operations.
To ensure continuous improvements, Google has introduced the V8 benchmark suite to upraise node.js performance with speedy execution, better compilers, security patchworks, and the capability to scale.
With a constantly growing consumer base of tens of millions of users, giants like Netflix, Walmart, Uber, PayPal, among others, have observed advantages of the Node.js web app as a practical solution for scalability.
The cutting-edge technology arises with loads of features like the cluster module. It simplifies load balancing over multiple CPU cores, and without burning out the RAM process, it makes it easy to deliver desired outcomes through smaller modules.
In addition, Node.js services a non-blocking event-loop mechanism that offers high scalability and enables the server to process requests effortlessly.
From the development point of view, Node.js allows you to power micro services that further lets you segregate your application into smaller modules. This way, you can define tasks and allocate them efficiently among different development teams. It will lead you to fast-track development, deployment, and maintenance of each division of your application.
One of the important advantages of the Node.js and micro service is that it allows modern apps to scale up and down as per demands. This way, it helps companies to achieve high performance with fewer resources.
By using micro services architecture and Node.js combination to replace its past legacy system, Walmart benefited enormously. Along with a 98% increase in mobile conversion, the retail giant saw a rapid growth of 20% in overall conversions. In addition, they did end up saving 40% of the computing power and also cutting costs by a massive 20-50%.
LinkedIn’s development team post migrated from Ruby on Rails to Node.js, and they gained performance momentum from node.js advantages. They reduced servers from 30 to only three. They started resource delegation and utilization more efficiently, shifted their focus from troubleshooting to app development.
Node.js community has millions of developers who are contributing actively. One can expect broad support from development professionals across the globe to solve even the strangest development problems.
NPM is the most extensive package manager registry in the world. It provides several tools and libraries available readily for use in your project. Developers will also have a large pool of resources – ready–to–use solutions, codes, modules, libraries, and registries- on GitHub made by developers to help accomplish goals more with limited resources.
IBM is profoundly supporting this ever-growing technology, which has acted upon its plans to sponsor and speak at important Node events to enhance the reach and usage of the technology.
This vibrant community is supported by many leading tech titans like Amazon, Google, Facebook, and Netflix, contributing to node.js massively. They have made outstanding contributions in the form of many open-source solutions. Acceptance by tech titans, alongside the developer’s community, guarantees tech presence and growth in the predictable future.
Let’s assume you have employed two teams for project development and quality testing, who work independently and whose responsibilities keep their expertise and working knowledge.
Even if this sounds ideal, chances are these teams have substantial communication gaps, resulting in massive holes in your product.
So, it sounds like a problem, yeah? Node.js is the solution!
Node.js offers full-stack development ability. It helps you make a team that focuses on enhancing your development life cycle wherein you can suddenly address challenges.
This work environment adds value to improved productivity and lets you resolve issues and troubleshoot them accordingly. As a result, you are very near to reducing your time-to-market.
Well, it’s a given that a continuous to and from of requests has a significant effect on an app’s response time and performance. If your tech stack is not prepared to handle loads of requests, then the value of the product diminishes quickly.
Node.js has a single-threaded event-loop model that offers a non-blocking asynchronous architecture. With this architecture, it does not create more threads hence employing fewer resources. It helps boost your application’s responsiveness as it deals with multiple concurrent users simultaneously.
The Caching module of Node.js makes it easy for coders to reduce task workload and re-execution of code.
So, each time the first module of the web application gets requested, it gets cached in the in-app memory. A User gets quick access to web pages without having to wait for too long.
Node.js allows the developers to get extended support for the various commonly used tools. For example, suppose you want to test the source code of the Node.js application; you can use Jasmin and other such unit-testing tools.
If you want to identify and install the project dependencies, you can make use of npm, a powerful package manager. For running tasks of the project, you can use grunt.
Node.js offers high extensibility, which means that Node.js can be customized and further extended as per the requirements.
You can also use JSON format for exchanging data between the web server and the client. It also helps with built-in APIs for developing HTTP, TCP, and DNS, etc., servers.
There are numerous benefits of Node.js. Also, there are other things that you should be aware of which may not be so ideal. It would be good to know these issues with Node.js when deciding about using it.
So, let us discuss some disadvantages of Node.js.
One of the most significant drawbacks of Node js most developers deal with is frequent API changes and the lack of stability that comes with those changes. So as a result, the developers are forced to continually change the access code to match the compatibility with the latest version of Node.js API.
Many NPM registries and libraries in Node.js are either poor quality or incomplete and not adequately documented. Hence this insufficient monitoring is complex if some amateurs develop a web application in Node.js.
Only well-qualified and sound experts with project experience can make your project successful.
Node.js is an open-source technology with a myriad of libraries and modules available which might result in a lack of high coding standards. It is thrilling to choose the right tech partner to build your web applications for extraordinary outcomes.
The technology overall responds a lot to callbacks due to the essential nature of the asynchronous approach. This function runs just after every task in the queue, safekeeping several queued tasks in the background that are still running.
The callback might outcome is also known as callback hell. It directly affects the performance and the quality of the code itself. This limitation practically makes it boring to understand and maintain the code.
Node.js has the advantage of being single-threaded and event-driven, but this same reason reduces performance while executing heavy CPU-based computing.
Node.js is so fast because of its non-blocking I/O model. It uses a single asynchronous thread, which cuts the CPU workload and avoids HTTP overcrowding.
Node.js offers various benefits for web app development like easy scalability, ease of learning, extraordinary performance, highly extensible, active support from a large community of developers, and much more.
The Disadvantages of Node.js is the instability of the Application, Programming Interface (API), lack of a robust library support system, and deficiency of expertized Node.js developers in the current market.
