What is Node.Js? Positive and Negative Aspects of Node.js Web App Development
When it comes to choosing the right development programming language and framework then it becomes crucial to consider several factors such as fast shipping to the market, costing and it’s maintenance charges. The programming language that fulfills all these requirements is javascript.
What is Node.Js?
Node.Js is an open-source project that was introduced in 2009 by Joyent. The simplest definition of Node.Js would be it is a javascript runtime environment that helps in the execution of the JavaScript code server-side. This open-source and cross-platform JavaScript can help in real-time network application development.
Node.Js Strength and Weakness:
One of the Node.Js reports suggests that Node.Js is the king when it comes to productivity and developer satisfaction and it is the first choice to build web apps. In this article, we can learn about what factors can decide Node.Js strengths and drawbacks. Let’s see the pros and cons of Node.Js
Pros of Node.Js:
1. Node.Js offers easy scalability
Node.Js is a lightweight technology. There is one key benefit of ode.Js is that it is considered the best option for microservice architecture. In Node.Js it is to scale the applications in horizontal and vertical directions. Node.Js also offers the option to add extra resources to the single nodes during the vertical scaling so it is highly scalable and provides a better option than other JavaScript resources.
2. Easy to learn
javascript is one of the widely used and popular programming languages among developers. For the frontend developers, it is quite easier to use Node.Js as a backend.
3. Single programming language
Node.Js offers developers a facility to write a server-side application in JavaScript. This can allow developers to write front-end and back-end web applications in JavaScript using a runtime environment. all the web browsers support JavaScript so that the deployment of the web application is much easier.
4. Known for offering high performance
Node.Js runs the JavaScript code via Google V8 javascript engine and it can compile the JavaScript code directly into the Machine code so this can process easier and faster in an effective manner.
5. Support of the large and active community:
Node.Js has blessed with a large and active community of developers who contribute continuously towards its further development and improvement. The groups of developers are well supported and providing ready-made and easy solutions and codes in GitHub.
6. Node.Js offers the freedom to develop apps:
There is one another significant advantage of Node.Js that it offers the freedom to develop apps and software, unlike other certain guidelines to developing apps and software.
7. The facility of caching single modules
This open-source run time environment of Node.Js single modules caching features. the first request from the module gets cached in the application memory that allows the applications to load the web pages faster and responds very smoothly to the end-user
8. Support for commonly used tools:
Node.Js developers get extended support for various tools, for example, you can test the source code of Node.Js by using Jasmine and other tools.
9. Node.Js is highly extensible:
Node.Js is called highly extensible, which means that you can customize and extend Node.Js as per their requirements. you can also use JSON to provide the scope for exchange of data between the web server and the client.
Drawbacks of Node.Js:
It is an obvious thing that every object is not perfect in all areas, and Node.Js is not an exceptional case here. It also has some disadvantages.
1. API is not stable:
This is one of the major Node.Js drawbacks is that it does not have any consistency. the API changes frequently and this increases the trouble of developers so that when it happens they all need to make changes in the existing code base to ensure consistency.
2. Time-consuming:
All the developers need to write everything from scratch and this is quite a time consuming, hence to make your project glitch-free, you need to hire Node.Js developers to develop and maintain the code.
3. Does not support multi-threading programming:
Node.Js does not support multi-threading programming, it is not compatible with heavy computing app development.
Conclusion:
The Node.Js is more advantageous to the developers compare to its disadvantages. what's more important is the fact that it has extended the area of JavaScript application and that is used for both frontend and backend servers. with the progress of time more and more business organizations have adopted Node.Js and get positive results.
