When you discuss front-end web development, the first thing that forms the part of the discussion is javascript. Javascript is considered to be one of the most popular and widely adopted client-side programming languages.
Node.js is a javascript run-time environment that is being rapidly adopted by the companies, as it allows the execution of applications at the server-side.
Some stats that show how amazing Node.JS is. Are mentioned below:
- Major companies such as Netflix, Amazon, PayPal, LinkedIn, and many more have adopted Node.JS for front-end development.
- It can improve the performance of an application by 50%.
- It can reduce the cost of development by 58%.
- When it comes to startups, Node.JS is no doubt, the primary choice of developers.
These amazing facts tell you that Node.JS is a widely adopted language and a career in this can be lucrative. This can be obtained by taking up an online Node.JS Certification Training and getting certified.
What is Node.JS?
An open-source JavaScript runtime environment that is executed outside of the browser is what is called Node.JS.
Built on Google Chrome’s V8 JavaScript engine, Node.JS is a very powerful Javascript framework. It facilitates in compiling javascript code straight to native machine code.
Ryan Dahl, software engineer and inventor of Node.JS describes it as, the most exciting single piece of software in the current Javascript universe.
It is widely used by the techies to develop server-side web applications. It allows the developers to use the event-driven I/O APIs which makes it suitable for real-time web applications that are data-intensive. With the application of event-driven, non-blocking I/O paradigms, it ensures the outstanding performance of web applications.
To make all the executions non-blocking, it operates on a single-threaded loop that is event-based.
There are various packages and modules used by Node.JS. These are libraries that contain functions and are imported from the node package manager or npm.
Node.js is an excellent choice when you need to build fast, highly scalable network applications, outstanding performance, quicker development, and other advantages.
Application areas of Node.js are:
- Messaging applications
- Streaming applications
- Real-time web applications
- Chat programs
- Social-media apps
- Collaboration tools
- APIs
- Multiplayer games
- Virtual emulators
To understand why node.js is best suited for the above-mentioned areas, let us see some specifics of the language:
- It generates dynamic page content on the go.
- It facilitates the developer to create, open, read, write, delete, and close files on the server-side.
- It provides you with support in editing, appending or adding, or deleting of data in the database.
- Node.js can also be used when it is required to collect form data.
- Node.js can be used to minimize or eliminate the waiting time and untangles the process by focussing on the next request only.
- Node.js is widely used for the execution of single-threaded and non-blocking programming that is asynchronous.
Advantages of learning Node.JS
When you think of learning Node.js, you might wonder if it is worth it? To see whether you should learn this javascript library or not, the biggest reasons for a yes’ are mentioned below.
- Node.Js allows you to write javascript on both client and server-side.
You can use this language throughout your application. So, you can become a full-stack developer by learning this language, and become an invaluable asset to your development team.
- Node.js enables you to develop an MVP quickly.
An MVP or minimum viable product is a chunk of software with just enough features such that the product can be released quickly and meet the customer’s requirements.
- Node.js is best to build microservices
Microservices today have become the new way of an architectural style which has increased flexibility and agility. It allows you to develop your product in a modular and focussed approach so that you lean over a specific module to develop an application.
- Node.js can be used for developing tools too.
Apart from web development, which is a primary application of node.js, it also allows you to build development tools so that it facilitates your web application development.
- With node.js, you can build complex and powerful features, without the need of writing complex code.
Wow!! That’s amazing. You don’t need to write complex code and still build powerful applications, and to help you with this, node.js is there. This is because of the asynchronous-driven architecture of node.js and the point that it is built on Chrome’s V8 javascript engine.
Apart from these excellent features, other advantages of node.js include high scalability, easy to learn, an active community for support and feedback, reduces time-to-market cycle, no need to switch from back-end to front-end, and more.
Career Prospects and Salary
No doubt, software developers are always in demand all across the globe. With the knowledge of node.js, you become eligible for full-stack development, which is a bonus skill making you the most preferred candidate for the same. When you go through job portals, you can find a lot of job openings for node.js developers. Currently, there are more than 4000 job listings on Indeed.com.
