Node.js is a cross-platform runtime environment for executing JavaScript on server-side and networking applications. It is an event-driven, lightweight, non-blocking I/O model, efficient, open-source and based on object-oriented programming principles. It contains a large number of open-source libraries in a package ecosystem known as NPM. It is good at handling JavaScript code to accomplish many front-end and back-end activities. It is suitable for creating real-time applications to run in an intensive distributed environment. The use of JavaScript across the stack helps Node.js unify the language and data format (JSON) allowing programmers to make efficient use of the available resources.

Crux: Node.js makes it possible to write both front-end as well as a back-end for any application using full-stack solutions such as MEVN or MEAN.
Node.js is single-threaded and may not be used pretty well by the aligned servers which double up as computational servers. They often tend to block heavy computation and the throughput/responsiveness that it brings across with each process in queue. However, Node.js has been carefully curated and finds its application with a wide range of servers.
Node.js however does come up with using semicolons, call-backs, comma-first style, using * for versions, GET and POST, using console.log for debugging limiting connections with default maxSockets value and stateless request-response paradigm which it has gradually got rid of, now allowing both client and servers to interact in real-time and accommodating state-full, 2-way requests-responses.
Node.js also resolves the problem of CPU bound tasks by starting a request and process the task during the time it shoots a call-back, and eventually, the task gets ready. This suggests a way to process the non-blocking (input/output) model in web application development.
| Criteria | Node.js |
|---|---|
| How does it affect the performance of the application? | Node.js is derived from JavaScript, is slower, but can be combined with frameworks to amplify the development process. |
| Concurrency and Scalability | Node.js makes use of a single-threaded, event-callback mechanism, suitable only for small projects. This feature does not make it concurrent. |
| Development Tools | Prominent libraries, frameworks, and tools available with Node.js: Best Nodejs Frameworks
Best JavaScript Based Tools for Node.js
|
| Error Handling | It makes use of throw-catch exceptions for Error Handling. |
| Learning Curve | Node.js is easy to learn due to the availability of many online/offline resources. |
Types of applications that can be built by Node.js:
Node.js makes use of single-thread to process tasks quickly. JavaScript makes it quick and occupies less memory storage. Frameworks help in fastening the development process of Node based Web Applications. Node.js community contains NPM which has become the world’s largest module system with millions of usable packages, libraries that bump off the need for threading. Node.js brings many more features to the table including speed, scalability, suitability for fast apps, intense I/O, push technology over web sockets, reduced interval time, use of native node, the addition of error code – all of which have made it a solution desired by live chats, social media apps, forums, ad servers, forums, stock exchange software and many more big businesses like Linkedin, Netflix, Groupon, Twitter, Walmart, Uber, Medium, Trello, Yahoo, GoDaddy, Mozilla, Airbnb etc.
Going forward many top node.js frameworks bring a lot of vital features for a very strong full-stack development framework like Garbage collection, event looping, processing memory, and many more CPU bound asynchronous operations to save memory and space requirements, here are the premier ones:
All these node.js web frameworks are JavaScript based and come forth with a simple, elegant, extensible syntax that is easy to learn and adopt. The code is reusable across frameworks, plus one application can make use of more than one framework. Most of these follow Model-View-Controller (MVC) Architecture, are configuration-centric, offer features like input validation, caching, authentication and other essential features like flexibility and simultaneously creating dynamic end-to-end REST API’s.
Node.js has often stood as the most favoured frontend as well as backend frameworks, competing against Angular, React, .Net core, Spring, Django, Cordova, TensorFlow, Xamarin, Spark and Hadoop – for its non-blocking I/O model, data streaming in real-time and ease of use with coding which is extremely productive.
Node.js is still a preferred choice for start-ups or smaller cross-platform app development projects. Node.js gains its popularity by being effective at what it is, incrementing, and subsequently amplifying the presence of a JavaScript-based ecosystem. It as well does not tend to break the compatibility between versions in many major ways. Drop us a query if you’re looking to hire a node.js developer!
