Why to Use Node js For Backend Development?

If you need high performance, concurrency, and scalability, Golang may be the better choice. If you require real-time updates, efficient I/O operations, and prefer the simplicity of JavaScript, then Node JS may be a better fit for you. Find out more about the differences between Node JS and Golang in our blog. Open Systems Technologies Microsoft Azure Cloud Engineer SmartRecruiters Node JS is also great for building APIs (app Programming Interfaces). APIs are used to connect different systems and apps, and Node JS makes it easy to build them to be both fast and scalable. One of the main ways LinkedIn uses Node JS is to handle a large number of simultaneous connections from users.

This may make it challenging to figure out the best solution for your purposes and again negatively impact the code’s quality. Recently, Node.js has been actively used in enterprise-level software. While there is still a lot of arguing about this, many large companies and global organizations, such as Capital One and NASA, have already adopted Node.js. And the enterprise Node.js ecosystem continues to mature with such tools as IBM API Connect, Triton by Joyent, N|Solid by NodeSource, Red Hat OpenShift, Trace by RisingStack and others.

When Can We Use NodeJS?

You can see it for yourself in our State of Microservices 2020 report. When using Node.js, you may exchange code between client and server apps, and you can use JavaScript for the entire development process, allowing for improved communication between back-end and front-end teams. This also makes full-stack development simpler and more accessible, as you no longer need to locate an engineer fluent in numerous programming languages. Also worth mentioning is Libuv – a core component of Node.js that supports asynchronous I/O operations.

Let’s dig into the circumstances where the application of Node.js might not be optimal. These two principles, combined with JavaScript’s event-based model, underscore the importance of grasping the fundamental components of Node.js application architecture. The second principle, the asynchronous paradigm, illustrates the commitment of Node.js to an asynchronous programming model.

Why use Node JS for your next project?

A techie should always be closely conversant with all the technologies which are being used in this tech industry. So far, we have got a good idea on NodeJs and when we have realized we should use it for our server side application. For example, let’s handle the error that would occur when we divide a number by zero. This error would crash the Node.js application, so we should handle this error to continue with the normal execution of the application. Unlike the NPM, YARN is not tied to a specific business or company, so it runs entirely on the support of its members and contributors.

• Developers know that a new “game-changing” technology paves way into the IT market every few months just to pass into extinction later but that is not the case with Node.js.
• It is used for building highly scalable, data-intensive web applications.
• Walmart, the largest retail corporation globally, adopted Node.js to serve its web and mobile platforms.
• Concepts like asynchronous programming and the way it operates on nonblocking input-output operations make its performance high.

Thus, when you hire Node.js developers, you’re getting people who can use a runtime environment to develop JavaScript-based apps for a website’s front and back ends. The number of concurrent connections that Node.js can manage is high. Node.js is a suitable backend for IoT applications due to its serverless design and support for real-time communication. IoT is based on many devices transmitting many little messages that must be processed rapidly. Node.js is utilized in developing scalable desktop and mobile applications and online and IoT projects.

Error Handling

The engine improves the performance by converting JavaScript language into machine code, readable by a computer. Thus, V8 engine is continuously evolving to speed up Web and Node.js ecosystem. Node.js is not a full-fledged programming language itself, but rather an environment for JavaScript execution. While having tools of its own, like native libraries, Node.js primarily uses JavaScript’s abilities and syntaxes. Node.js applies a progressive event-driven pattern with an event-loop that replies to specific events.

Node.js shines in real-time web applications employing push technology over WebSocket. This is in stark contrast to the typical web response paradigm, where the client always initiates communication. Node.js outperforms conventional server-side technologies due to its high-performing, scalable, single-threaded, non-blocking architecture. It brings JavaScript to the server side, unifying the web development language.

Further, we will answer this question and leave you with a verdict as well as provide some insights on Node.js. Symfony is a PHP framework which automatically provides it with 20+ years of documentation, and a massive, active community. More than 77 percent of the web is powered by PHP with projects https://traderoom.info/how-to-emphasize-remote-work-skills-on-your-resume/ like Facebook, Baidu, or any other website running on WordPress. While Symfony is just one of PHP frameworks on the market, it’s impressively stable, scalable, and works well for large-scale projects. It also uses a templating engine Twig that works like many PHP-based Content Management Systems.

One initialism – npm, a default Node.js package manager — also serves as a marketplace for open source JavaScript tools, which plays an important role in the advance of this technology. With more than 1 million packages in the npm registry, about 42 thousand dedicated to Node.js alone as of now, and over 10,000 new ones being published every week, the Node.js ecosystem is quite rich. The same stats point out that 97 percent of modern web applications consist of npm modules. Node.js was declared the technology of choice when building and deploying microservices ecosystem solutions, according to Node.js User Survey Report back in 2017.

As was previously noted, Node.js uses Google’s V8 JavaScript engine to decipher JavaScript code. The engine performs a native compilation of JavaScript into machine code. Because it is based on widely used web languages, Node.js has a relatively low learning curve. Node.js is built-on on the concept of single-threaded programming. Cluster is a module that allows multi-threading by creating child processes that share the same server port and run simultaneously.

• As the most popular programming language, JavaScript is also one of the most universal software development technologies.
• The IoT community is also embracing the power of Node.js for embedded devices and robotics like Cylon and Nodebots.
• For these reasons, Node.js is a popular choice among «single-page application» sites, where all the rendering is done on the client’s side, and the backend only provides a JSON API.
• When the server has thousands of connections simultaneously, the Node.js processes them in the priority order in one thread instead of spawning a new one.

This aligns seamlessly with the event-driven essence of JavaScript. With clever use of callbacks and event-driven programming, Node.js optimizes resource use and bypasses the potential bottlenecks inherent to synchronous operations. Yesterday my title with Packt Publications, Reactive Programming with JavaScript. It isn’t really a Node.js-centric title; early chapters are intended to cover theory, and later code-heavy chapters cover practice.
