Node.js features, Benefits & Disadvantages in Nigeria
What is advantages of using node js?
js really shines in building fast, scalable network applications, offers benefits in performance, faster development, and other perks. Today’s requirements for processing and consuming real-time information are paramount, and Node. js is exceptionally fast for multi-user real-time data situations.
Node.js Benefits in Nigeria
As it’s a single threaded program , It offers many options for having a good grip over run-time executions such as call-back methods & event loops , Node package modules (npm) has already increased in size & It is still growing , Streaming big files is possible with Node.js .
Node.js is open source , so it is free to use & you can extend it as per your need , There is no need to pay for license & There are many open source modules supported by Node.js , Event-driven architecture of node.js is appropriate for the real-time applications , especially the chat applications & the games .
You can scale your Node.js application by using two ways the Horizontal Scaling & Vertical Scaling , that helps you to improve your application performance , In Horizontal scaling you can add more nodes to your existing system and in Vertical scaling you can add more resources to a single node .
Node.js is easy to scale , The developers have the option to scale the Node.js applications by using two ways which are the Horizontal Scaling & Vertical Scaling , that helps the developers to improve their application performance .
Node.js offers a wide community of developers around the world , They are active in development of new modules or the packages to support different types of applications development , PayPal reported 2 times increase in developer productivity after using node.js .
Node.js supports caching of modules , Each time a module is requested for the first time , It is cached in the application memory , The application can load the cached modules quickly without requiring the module code to be re-executed , The caching feature enables the application to load the web pages & respond to the user requests more quickly .
When you use Node.js , you can develop Restful services API easily , Despite being lightweight , Node.js offers some built-in APIs that help you to create different types of Servers like HTTP Server , DNS Server , TCP Server etc. and Node.js helps the developers to take advantage of many commonly used tools .
Node.js disadvantages in Nigeria
Node.js is isn’t consistent , It does not support the relational databases , Using it is difficult for the programmers for high intensive computational tasks , It is important to use the callback end up every time with the bulk of nested callbacks .
Many programmers complain that Node.js API ( Application Programming Interface ) keeps changing at frequent intervals , The new API comes with a number of backwards-incompatible changes , So , it is important for the programmers to make the changes to the existing code base to make it compatible with the latest version of Node.js API .
The asynchronous programming approach is important if we want to enhance Node.js scalability , The developers have the split opinion on this as this approach is quite complex than the linear blocking I/O programming and it makes the code messy .
Node.js at present , isn’t supportive to both multi-threaded programmings , So , It is unsuitable for large and complicated web applications , It doesn’t support multi-threaded programming , Node is good for executing synchronous and CPU intensive tasks.
What are the advantages of NPM?
Following are the uses and advantages of NPM:
- Manage local dependencies of project’s tools.
- Manage globally-installed project’s tools.
- Manage multiple versions of code and code dependencies.
- Download standalone tools you can use right away.
- NPM provides package-lock. json which displays all dependencies of the project.
