Node.js package management is one of the most fluid parts of the Node.js community. The npm CLI is the utility that ships with the Node.js binary, but for years it had many glaring issues. Yarn was launched as an alternative that had some big name sponsors attached, and fixed many of the issues that npm failed node.js developer job to deal with. But competition breeds innovation; npm not only fixed those issues but is innovating in the world of package management beyond the features of Yarn. Today, it’s almost a toss up which one you should use, but having experience with a package management solution in Node.js is an essential skill.

The functionality of running scripts server-side produces dynamic web page content before the page is sent to the user’s web browser. Node.js made JavaScript a full-stack technology of choice for web application development. This might be social networks, gaming apps, live chats or forums as well as stock exchange software or ad servers, where speed is everything. Fast and scalable, Node.js is the technology of choice for data-intensive, real-time IoT devices, and applications.

It’s based on Google’s V8 engine that compiles JavaScript to machine code and ensures its super-fast execution. Node.js has an event-driven architecture and leverages asynchronous programming. Those features allow Node.js servers to process huge numbers of I/O requests coming from multiple clients at an unbeatable speed. You will be responsible for developing the server side of the application, designing the application logic, and maintaining the databases.

By partnering with Full Scale, you will have the benefit of selecting a highly-skilled offshore Node.js developer of your choice. All you need is to provide a detailed requirement of your developer, and we can match you with one in our team. The Philippines is one of the most popular offshore hiring destinations. The cost-effective option is not due to a lack of experience and talent. These countries offer lesser costs due to the difference in cost of living and the local economy. The tool allows developers to prototype quickly and follows the lean startup technique.

Written in C++, Chrome’s V8 is used to compile functions written in JavaScript into machine code, and it does the job at an impressive speed. Thanks to Google investing heavily in its engine, V8 demonstrates performance improvements every year, and Node.js extracts the whole bag of benefits out of it. Event loop collects new callbacks and polls for new incoming requests from the event queue when other operations are finished. The philosophy behind Node.js is to let the application do its work and perform operations even when the previous operation hasn’t been completed because of input/output bottlenecks.


Since Node.js uses JavaScript programming language, this skill is an indispensable requirement. Ensure that the central database achieves optimal performance and responsiveness when it comes to front-end requests. In summary, Node.js is a dependable tool to make code writing easier and faster, hence its popularity in the industry.

Check out our services for hiring enterprise talent or hiring startup talent today. Being a single-threaded runtime environment, Node.js is not suitable for the execution of CPU-intensive tasks. As all incoming requests are processed one by one, a heavy-computation task can block the main thread from processing all the subsequent requests. To cope with this drawback, Node.js offers a Worker Pool that summons a few separate threads for the execution of expensive tasks. However, if your app requires resource-consuming computation, it’s better to use other languages on its backend. The mobile application is no longer split into two distinct paradigms.

The bottom line is that you should know one of these database solutions well. Security on the web has always been a big deal, but with all the breaches and issues recently it is positively a necessity now.

As mentioned above, the development of Node.js was supported by Joyent. The V8 engine used in Node.js implementation was originally developed for the Chrome browser.

  • To address the issue, third parties have introduced open-sourced С/С++ wrappers on top of the API that partially alleviate the problem.
  • Experience functions as proof that a developer has been in the field long enough to be familiar enough with the skills, knowledge, and processes necessary to be a good employee.
  • A Node.js developer is responsible for building server-side web application functionality in JavaScript and/or JavaScript variations such as CoffeeScript, IcedCoffeeScript, etc.

David has been developing websites and web applications for all of his adult life. As a software engineer, he’s worked for many diverse software companies from early-stage startups to Google. David is experienced with many web frameworks and environments, but he particularly enjoys developing with Meteor.js. He appreciates the importance of quality code as well as the need to meet scheduling demands. A Node.js developer must create database schemes that represent and support business processes.

There’s not a lot of technologies that can compete with Node.js’ popularity or market demand. However, if we look at the alternatives for server-side programming, we see at least three more shining stars in the sky. Let’s see whether they hold up to Node.js’ benefits and share its drawbacks.

⊕ Seamless JSON support

Node.js has stood the test of time and got a rich ecosystem maintained by the JavaScript community. Node.js has proved to be a super lightweight, scalable, and fast backend tool for event-driven real-time apps, single-page apps, and microservices. The use of Node.js helps startups benefit from full-stack JavaScript development, which simplifies and streamlines the app development cycle.

However, as mentioned in the article, the issue has never really existed for skilled JS developers. Not to be curmudgeonly, but .Net core was handling 1.15M rp/s back in 2016. As much as I like the platform semantically, Node’s perf numbers are bush league. Other than the language itself, there’s no real reason to choose one over the other.

Lightweight, Fast Applications with Real-time Communication

According to W3Techs, Node.js is used by 2.1 percent of all websites, which number at least 30 million. Experience functions as proof that a developer has been in the field long enough to be familiar enough with the skills, knowledge, and processes necessary to be a good employee. The more experience a developer has, the more employers can trust that they have senior Node.js developer skills, and it’s a good investment to pick them. As a result, Express has enjoyed widespread popularity in the market and is used by more developers than any other web application framework. Express is so well received because it can help you get up and running quickly in most new code bases.
