Pros of Node.js trends that will dominate in 2021
For backend, Node.js offers various benefits such as:
- Sharing and recycling of codes.
- Easy understanding
- Multiple free tools
- Good speed and efficient performance
Besides these benefits, it has some more advantages for backend use:
- V8 Engine
- Handle the asynchronous and non-blocking input or output request
Node.js prevents delays by processing requests of the user. The synchronous processing shows the code execution in a proper sequence in backend development. That is how each request is blocked and requests others to wait until the first one is finished.
On the other hand, asynchronous processing permits the requests without blocking the thread. This way, it pushes out a callback after processing the request and further continues their request service.
This feature helps Node.js for short response results and concurrent processing. There are many leading companies who prefer Node.js applications to notice significant improvisations. The companies like PayPal have seen a 35% decrease in response time after migrating to Java.
- Scalable technology for micro-services
This technology of Node.js is light weighted and the best choice for micro-service architecture. The micro-services do not create a single and sizable monolithic core but break the applications into logical and smaller modules.
The breaking of the applications offers fantastic flexibility and better groundwork for future growth. That is the reason that adding more microservices on top of the existing application becomes more straightforward rather than integration of extra features with better functionality of the basic app.
As per the reports of the Node.js User Survey, the ecosystem of microservices is optional, and more than half of respondents are using this technology for the development of Node.js web apps.
In the form of live implementation, the micro-services architecture of Node.js has the following immediate advantages:
- It increases the conversion rate by 20%, with a 98% mobile conversion rate right after use.
- It is handling more than 500 million page views, thus offering 100% uptime on Black Friday.
- It saves almost 40% on hardware and 20 to 25% over other operations.
The npm registry consists of 836,000, and more than 10,000 new libraries are being published every week, which makes Node.js a technology-rich environment for developers. As per the sources, more than 95% of modern web applications consist of npm modules.
Npm Module has a wide range of free tools accessible in a few clicks that offer vast potential for Node.js. On the other hand, the open-source software offers enhanced popularity that brings a new solution for the deduction of the overall developmental costs and time to market.
- Effortless support of JSON
Cons of Node.js trends that will dominate in 2021
It has the considerable possibility that beneficial technologies like Node.js may have some cons too. Node.js have some following disadvantages that create obstacles:
- Call Back hell issues
Node.js has an asynchronous nature, which is the biggest problem for programmers. Node.js is dependent on heavy callbacks. That is the feature processed after every task in a straight row after finishing the first one. The programmer may face callback hell by keeping numerous pending jobs in the background along with its callback.
This Callback hell results in bad code quality. Simply it creates a situation in which callbacks are nurtured with more callbacks of more profound levels. Thus it becomes complicated to maintain an understanding of codes.
- Immaturity of tooling
Whereas the modules of Node.js are stable and considered as mature in terms of features and services. But besides this, there are many tools in the registry of npm that have lousy quality standard and non-tested documents. The registry is not well structured to offer the best tools depending on their rating or quality. Thus, it makes it challenging to find the best solution for your issues.
Everybody knows that the ecosystem of Node.js is an open-source platform and affects programming. Although, the quality of Node.js code technology is supervised by Joyent and other professional contributors. But the rest of the tools may lack good quality and high coding standards set by the global organization.
- Continuous demand for experienced professional
- Bad performance of bottlenecks with heavy computation tasks
The meaning of the input or output model is that Node.js asks the clients to start a request and begins the task process at the time of the shoot callback when the task is completed. The asynchronously processed task executes Node.js on a single thread at the basis of the event, and this is called event-loop.
Along with the given pros and cons, the ecosystem of Node.js is gaining popularity in significant traction due to the presence of its features and efficiency. There are many companies that are hire Node.js programmers to develop platforms for global brands.
They are offering good growth of framework. At present, Node.js is widely used in multiple enterprise-level software, and this enterprise ecosystem is offering various tools such as IBM API connect, Triton by Joyent N/Solid by Node Source Red Hat OpenShift, Trace. Many to count as many reputed companies like NASA and Capital One are adopting Node.js with open arms.
