Node.js framework – A Panoramic view for Web Designers & Developers
It often happens that something new arrives, and it becomes so popular that you feel regret not learning it earlier. Make sure you never do that with Node.js. If you’re not familiar with it, let me help you.
What exactly is Node.js Framework?
Have you ever heard about Node.js framework before? Let me give you a brief introduction to Node.js.
Do you know why Node.js framework is a lightweight (in terms of in-memory usage) and an efficient tool?
Just because it uses an event-driven and non-blocking I/O model which is very helpful for data intensive real time web applications running on various distributed environments and/or devices. Unlike PHP and ASP, Node.js helps you eliminate the waiting time and simply continue with the next request. So if you’re looking for an open source and cross-platform runtime environment for web development, Node.js best fits your needs.

Node.js Latest Version
The Node.js 8 has successfully replaced the previous version 7, and now available with the unique features. The Node.js LTS (Long Term Support) will be released by October 2017. First and foremost, the LTS release will focus on the stability and security. No doubt, if you’re looking for a guaranteed stability in web development with the Node.js framework, the upcoming LTS release would be the best fit for your need. The latest version of Node.js is v8.3.0, and v6.11.2 LTS (Long Term Support). If you’re a network application developer, the latest version offers you plentiful opportunities, Also, you’ll definitely notice a lot of other improvements which will make the user experience better than before. To download the Node.js latest version, you can simply visit the Node.js® website. Moreover, you can find all the required information over there.
What’s new in Node.js?
If you’re truly a diehard fan of Node.js, then, you would be happy today. Am I right? How do you feel now when you see the wait is finally over? Many of you would’ve updated your Node.js so far. Do you like the new version? Of course, you do. Above all, it’s Node.js. For those who’re still using the old version of Node.js, I would like to say go and update your Node.js guys. Why? Just because you get these extraordinary features.
1. Use of Async Hooks API
The Async Hooks, formerly known as AsyncWrap, is truly a noticeable feature of the Node.js 8. In order to get updates on life-of-handle objects by structural tracing, you can take help of the API (Application Program Interface). Moreover, the web developer can easily control the Node.js event loop function by using this latest version.
2. N-API vast advantages
3. NPM 5
The latest release of Node.js uses the latest NPM (Node Package Manager) 5, one of the best attributes. Therefore, the web developers can use it with no hindrance at all during the development process.
4. Enhanced Buffer Security
The node.js framework contains two buffer types: zero filling buffer and new buffer. And both are added by default. But in the earlier version of Node.js, the memory space was not initialized with zero. Since the Buffer instance contained sensitive information, this was the main reason why a Node.js user faced security issues. As a result, in this latest release, you get an enhanced buffer security.
Node.js for Web Development
- Excellent Running Speed
- Ideal for real-time applications
When it comes to real-time applications development like chats and gaming apps, Node.js provides you some extraordinary features. Furthermore, it’s considered as the best solution for the programs which need event-driven as well as non-blocking servers.
- Smart Sharing
Node.js has a built-in NPM or Node Package Manager, a robust and a consistent solution for developers. It provides you a smart sharing feature. The NPM which includes the repository of 50,000 packages, helps you create effective solutions. And, via NPM, you can update, share as well as reuse the codes with ease and utmost accuracy.
- Coding Single-Handedly
- Advanced Data Streaming
Generally, the requests and responses from HTTP are taken as isolated events. But the fact is that they’re data streaming. This data streaming feature is extremely helpful with the Node.js framework. Being a web developer, you have an extraordinary advantage if you’re creating features like processing files while they are being uploaded. This will actually reduce the complete processing time. Also, if you’re working on real-time audio or video encoding, this feature will prove to be a boon for you.
- Act as a Proxy Server
If you want to proxy multiple services with differences in their response time, Node.js offers you some fantastic features. It provides you a great help in streaming the data from the different sources. If any enterprise lacks the professional proxy infrastructure, the Node.js framework can act as a proxy server. Also, if you’re using any server-side application for any specific purpose, for e.g. communicating with 3rd party resources, storing images, and/ or data collection, you can use Node.js.
Where to use Node.js?
I hope you’ve become more familiar with the Node.js framework and its aspects. Now you must be wondering where to use Node.js. I’ll help you understand in which areas Node.js can really help you.
