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 is the server which can execute JavaScript , It is an open source , cross platform to make the real time network applications , It offers asynchronous & event driven I/O APIs , When it runs single threaded event based loop , all the executions become non-blocking .


Node does not deal with PHP , .NET or JAVA , It is not a framework , It is a server such as Apache , IIS , TOM etc , It executes JavaScript in the server side , JavaScript without the browser is Node.js , Node itself is not made in JavaScript completely , But its wrappers are made in C and it just executes JavaScript.

Although there are drawbacks of using Node.js , Many features of it will help in creating a wide range of networking and server-side applications in JavaScript , Node.js is the most common & widely used server side framework for small , large and any sized web app & web application development.

JavaScript is more popular than the other client-side programming languages, As a cross-platform run-time environment , Node.js enables the developers to run JavaScript on the web servers , But Node.js is different from the other commonly used JavaScript frameworks , It interprets the JavaScript code through Google’s V8 JavaScript engine.

Node.js Benefits in Nigeria

You can use a Single Programming Language , Node.js enables the developers to write the server-side applications in JavaScript , So , the developers can use the run-time environment to write the front-end & back-end of the web application in JavaScript , without using any server-side programming language.

As JavaScript is supported by each the web browser & the server , it becomes easier for the businesses to deploy their web applications more effectively , Node.js is easy to learn , So , The basic Java programmer will find it easy to upgrade to it , It uses JavaScript as a programming language which increase programmer productivity & code reusability.

The synchronization process is better & quicker , The asynchronous event-driven IO assists concurrent request handling , The community is very active & vibrant with several codes shared by GitHub, etc , Node is not multi-threaded , It runs in a single thread with callback concept , It’s not for JavaScript beginners as it is very low level .

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 .

The developers can add extra nodes to their existing system in Horizontal scaling & They can add more resources to a single node in Vertical scaling , These options make Node.js more scalable than the other JavaScript frameworks available in the market .

Node.js delivers improved performance , It executes JavaScript code through Google’s V8 JavaScript engine , The engine compiles the code written in JavaScript into the machine code directly , So , This code is executed in a faster & efficient way , The run-time environment increases the code execution speed by supporting non-blocking I/O operations .

Node.js is highly extensible , It is based on JavaScript that can be executed on the client side as well as the server side , Its open source nature makes it easier for the programmers to customize & extend Node.js , It supports exchange of data between the web server & the client by using JSON that is consumed by JavaScript easily , This makes it light weight as compared to the other frameworks .

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 supports unit testing out of box , The developers can test the source code of Node.js application by using Jasmin & JavaScript unit testing frameworks , They specify & install the project dependencies more efficiently by taking advantage of the robust package manager like npm , They have option to use grunt as an efficient task runner for the project .

Node.js can facilitate the Real-Time Application Development , It is used by JavaScript developers for building the real-time & multi-user applications such as the games & chats , The run-time environment uses web-sockets simplify & speedup bidirectional communication between the web server & the client , As the web-sockets run on TCP , the overhead on HTTP remain unchanged .

Node Js features, benefits & Disadvantages in Nigeria

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 .

JavaScript does not have a strong standard library , unlike the other modern programming languages , The users do not have any option to avail popular libraries for the image processing , The object-relational mapping (ORM) , database operations and XML parsing .

Many developers find the available JavaScript to be unstable & inadequate , So , the developers find it difficult to accomplish popular programming tasks while using Node.js , If Node.js executes long running task , It does not support very high computational intensive tasks , It will queue all the incoming requests to wait for execution , It follows JavaScript event loop that is single threaded .

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.
