Why Node js ?
What Is Node.js?
Node.js is a back-end and open-source coding platform that allows you to write server-side enterprise-level too scripts. The platform is efficient and lightweight. In addition to this, it also allows for the development of front and back-end with the same language.
Apps created with Node.js are entirely different from the ones we run on browsers. Javascript is a common denominator while building web apps. It’s the Node.js environment that helps you exercise more control and convenience with the development process.
Why Use Node.js? Node.js is the best when it comes to server-side technology, It offers the same tech for both front and back end. This reduces your development cost. And due to the presence of Javascript, the application code is understood by all developers. It also adds to your development speed by allowing you to share and reuse code between the front and back ends of your app.
The platform has also managed to create a huge community that answers all your doubts and queries on numerous portals. Thus, there is sufficient knowledge that one can access if they get stuck with the development. The language also offers a Node.js package manager that stores different tools for quick app development.
The following contribute to high development standards of node js:
It uses an ‘event loop’ to encapsulate user requests in a single thread. This feature is useful when one has to process huge volumes of IO-bound requests. A feat that is highly used by Node.js web development companies while creating enterprise-level apps.
Perfect for Creating Single Page Applications The page does not load every time once the site has been loaded on the browser. These apps are created with the sole aim of lowering the page load time to offer a seamless user experience. And providing quick navigation to different pages such as desktop apps. This is the reason why developers prefer using Node.js with React to develop SPAs. Using the same you can only make calls where you need to update or dynamically change the DOM while controlling the logic of the app.
Seamless Integration and Quick Development One can achieve seamless integration between the back and front end of an app when coded using the same platform. This is an important feat for real-time and event-based apps. Node.js is extremely fast at converting Javascript code into machine code because it runs on Google’s V8 engine which is also built on JavaScript.
Real-Time Apps Used by online gaming, instant messaging, live-chatting, and many other collaborative apps such as Trello. As they require immediate response and have to perform within a particular time frame. Node.js is the perfect language to create such low latency apps.
Efficient Data Streaming Node.js efficiently manages data streams with I/O bound apps. Though there are few options to choose from, data streaming is one of the most powerful implementations of Node.js. This can save a lot of time during processes as a majority of the data that enters the stream is in form of streams.
Easy Installation Facilitating back-end operations smoothly is an important part of any framework. The support tool that comes with Node.js installation: Node.js Package Manager provides ease for developers.
Microservice Architecture This always happens when one tries developing a new application. As time passes you would notice that one part of your app functions better than another and the other part needs quick scaling.Using microservice architecture with your Node.js is a great combination to work with.
Extensibility One can customize and extend the functionality of their app as the platform is highly expandable. An aspect that is highly leveraged by Javascript development companies. Data exchange between the client and server can be done by making use of JSON. One can also create HTTP, DNS, and TCP servers by making use of built-in APIs.
** Examples of Apps That Can Be Created Using Node.js
Chat Systems** This online solution is the strength of this framework. If created using the appropriate web sockets, the most active chats can be created as imagined. They will be proficient with handling huge chunks of traffic and offer high delivery speed.
Streaming Services Node.js is best suitable for streaming services as it uses the input/output model. Due to the preceding users can use active connections with simultaneous upload and downloading of data.
Online Games Only a few runtime environments are capable of handling a large number of connections that have to be managed with online games. To its advantage, Node.js has been created to handle such situations. The platform allows quick synchronization between client and server data and allows players to play multiplayer games.
REST APIs If you wish to develop efficient, lightweight, and responsive APIs you should combine Node.js with another Javascript framework named ExpressJS.
Single Page Applications (SPAs) Developing SPAs along with NJS is a great combination. This is because with SPAs pages can be loaded in the server before it’s presented on the browser. Thus content rendering is faster for the user
Conclusion
"It’s not a magic bullet, nor is it appropriate for all programming scenarios. But, the common wisdom among many developers is that there is no single right language that must be used for all web apps. But Node is increasingly being seen as a “best solution” for a certain type of application."
