Find the reasons for the involvement and evolution of Node.js across client-server environments!
Considering all this discussion, Node.js was created to fulfill a certain purpose – to devise a system for building websites with real-time push capability. This is exactly the case of the "Gmail" mail-server application. For this very reason, the event-driven paradigm became the heart of Node.js. PayPal, Netflix, Uber, eBay, LinkedIn, Groupon, PayPal, Walmart, Twitter, Medium, eBay, Trello, Yahoo, Mozilla, GoDaddy, and Airbnb, etc. are some distinguished platforms developed in Node.js.
What makes Node.js exclusive?
Things to Know About Node.js
- Node.js is not a framework.
- It relies on Chrome V8 Engine only.
- Node.js does not support multi-threads.
- It is an open-source and cross-platform system for building web applications.
- Node.js provides asynchronous and event-driven API’s.
Cues for Node.js Web Application Development
- Node.js community readily shares packages of codes. There are almost 475k code packages in the NPM alone which has grown from package manager to a repository. So in case, anything is challenging, chances are that a solution is already available.
- Node.js comes with fine instrumentation, best practices, and documentation. It is always aimed at uplifting every stage of app development, best performance and readiness for production.
Discussing the Points in Favor of Node.js
- A runtime environment supporting the caching of modules
- Event-driven input/output (I/O) ensures better request handling
- Same code for both server-side and client-side = painless deployment of web applications
- NPM – the biggest package manager in the software world
- It is also possible to stream large files
- Preferable as a full-stack development framework due to features like Garbage collection, process memory, event looping, Node’s ability to be CPU bound and use asynchronous operations helps save memory and space requirements.
- Node.js applications can be scaled up vertically as well as horizontally.
- Node.js supports the caching of individual modules.
- It supports creating applications in real-time.
- It can be easily scaled up and extended.
Major Node.js Frameworks
Here is a list of some frameworks supported by Node.js with an elegant syntax. These are simple, stable and are based on MVC web application architecture. These are configuration-centric, often utilize connect style middleware, and offer features like authentication, input validation, caching and some other essential facilities like flexibility and creating dynamic end-to-end REST APIs.
Points To Be Careful About Node.js
- Inconsistently enhancing API
- Not an optimal solution for tasks intensive on CPU in comparison with low-level languages like C, C++, C# or Golang
- Split opinion about the asynchronous approach
- Node.js is still evolving. New API add-ons might be incompatible with changes backward.
- It follows the asynchronous programming approach rather than linear blocking I/O programming.
- Node.js is particularly not suitable for developing large or complex applications as it does not support multi-threaded programming. It queues incoming requests and executes them separately in case long-running tasks have to be processed.
Best Application Types with Node.js
- Chat Applications: For creating a typical, interactive real-time chat application to endure big traffic, intensive data and running across devices.
- Server-Side Web Applications: Node.js can become even more efficient if combined with other runtime environments like Express.js to create apps that are low on CPU computation and can simplify development.
- Data streaming: Node.js can be used to create applications used to process large files, audio/video encoding, etc.
- Dashboards: Node.js often works well for creating monitoring dashboards to collect information from visitors in real-time.
