Hire Node.js developers remotely within 3-5 days

According to Stack Overflow, Node.js is the most common web technology used by professional developers and those who are learning to code: almost half (~47%) of the respondents surveyed by the company in 2022 turned out to be Node.js developers. 

What else speaks in favor of the popularity of this backend language is the great variety of companies, from small to enterprise-scale, that use it. The websites of giants such as Walmart, Medium, PayPal, Uber, LinkedIn, Yahoo, Trello, eBay, and Netflix were written with the help of Node.js experts.

Read on to see if your team should also hire a Node.js developer!

Node.js Benefits: What Node.js Developers Bring to Your Projects 

Node.js is a JavaScript runtime environment that makes JS, a language that’s usually utilized for front-end tasks, a general-purpose language. It does this by adding tools and features that make it handle the back-end. It is also called the JS runtime. With Node.js, you can create websites and high-scale apps using only JS: with Node.js for the back-end and React JS, Angular, Vue, etc. for the front-end. 

Node.js is one of the most popular platforms for building efficient and scalable REST APIs — in layman’s terms, “connectors” between different apps and services. It is also suitable for building hybrid mobile applications, desktop programs, and even IoT.

Ryan Dahl developed Node.js in 2009. Before this, servers had a “one thread per connection” approach, and Dahl came up with an event-driven system. It reacts to an action or inaction and allocates resources for it, distributing reactive “power” across the system. That’s why it’s easy to build scalable network servers with Node.js. 

Node.js is fast & has high performance

Node.js is fast, and its V8 engine enables its speed. V8 is an open-source JavaScript engine licensed under the BSD license. It is used in Chromium-based browsers. This means that Node.js uses the work of thousands of engineers. The engine is written in C++ and has open-source code and advanced libraries. Because Google pours tons of money into making V8 as high performing as possible, Node.js inherits that property. 

Another important advantage is asynchronous request processing. JavaScript code that runs in Node.js can be several times faster than code written in languages ​​like Ruby or Python because Node.js uses the asynchronous programming model. Within these models, requests are completed without delays even when several other tasks are being processed when they are made (whereas synchronous models wait until secondary tasks are completed before starting the new one). When an I/O operation needs to be performed, such as accessing a file system or a database, Node.js does not block the main thread waiting for the results of the tasks that are running. In turn, the main thread is pushed to the execution via single-threaded processing Node.js utilizes.

Node.js is used for products that require constant data updates and real-time handling and processing of these updates. This includes online games, chats and communication platforms, tools for video conferencing, fintech tools, and so on.

The most prominent examples from the wild speak for themselves. Many leading companies have noticed significant improvements since switching to Node.js development. PayPal has migrated its backend from Java and reduced the response time within their resource by a third.  

What does this mean for your business?

• Your product is fast
• Google ranks fast websites higher
• Better user experience for your visitors, because response/download time is one of the main factors impacting first impressions > more efficient user acquisition 

Node.js-based web and mobile apps scale well 

Node.js helps develop scalable applications because it can handle multiple requests simultaneously. Node.js apps don’t overload the CPU even with a significant increase in requests, which means it’s a perfect tool for, e.g., social media. 

Node.js provides ample opportunities for expanding the application, adding functionality, and updating tools with minimal labor and financial investment. If a company grows, develops, or even changes its original business model, Node.js reacts flexibly to any changes. All this is done thanks to microservices.

Development of microservices refers to, basically, presenting your web app’s component as a set of little services. Adding one or editing an existing one without disturbing the rest of an app is easy. Node.js is a very good solution for ecosystems like that, and according to Node.js User Survey Report 2020, it’s a preferred one. Architectures like this enabled scalability and high application performance since each microservice communicates directly with the database — and makes it robust. 

Walmart’s transition to a Node.js-based microservice architecture got them a 98% increase in mobile conversions: for e-commerce resources, speed and performance are essential, and investing in them brings very quick results.  

Node.js developers for hire can outperform competitors in terms of performance — GoDaddy’s case is an example of that. Because the company used Node.js, when their Super Bowl ad campaign brought a lot of users to them, they could handle 10k requests/second without delays or downtime (and they’ve used only 10% of their hardware capacity.) 

What does this mean for your business?

• The right architecture allows you to scale your business without investing a lot of money
• Scalable apps can, again, easily handle a growing user base — and process a lot of requests without putting a lot of pressure on the system 
• Apps built on microservice architecture can be upgraded and edited quickly.

The Extensive JavaScript ecosystem provides support & community

The Node.js ecosystem is growing rapidly thanks to the NPM (Node Package Manager). It contains over 500,000 open-source modules and libraries that are freely available. There are also new ones all the time. As you imagine, that helps build web applications quicker. 

Also thanks to the high popularity of JavaScript and Node.js it’s easy for a web developer to find a solution to their issue. A lot of people work within the ecosystem.

Plus, the development of Node.js was supported by Joyent — a foundation that was created to boost the tool’s development. IBM, Microsoft, and other tech companies invested heavily in it, so it’s fair to conclude they’ll continue to see it improved and promoted. So, by hiring Node.js web developers, you’re joining its very successful user base. 

What does this mean for your business?

• Big tech support makes Node.js a promising technology
• A lot of programmers use and develop a Node.js ecosystem = a high level of reliability and support within the community 
• Fewer continuity and transfer errors occur, so development gets more streamlined (at the junction of different development technologies with different types of data, floating bugs often occur, but with Node.js using JavaScript, there are fewer cases like that).

Projects Node.Js Is Perfect For 

Powerful Single-Page Apps

A Single-Page Application (SPA) is a product that is represented by a single web page that is loaded into the browser and whose content is dynamically updated as the user interacts with it. Or, SPAs are the websites that are updated without reloading, like Twitter, Facebook, Gmail, Tumblr, — you got it.  

A lot of loading pressure within these SPAs falls on client-side (front-end) JavaScript, which, without good rendering mechanisms, negatively affects loading speed. That, in turn, hurts the app’s user experience and SEO ranking. A popular solution to these problems is server-side rendering with Node.js, and that’s one reason why Node.js is a popular backend technology for building SPAs. 

Apps for the Internet of Things

Since IoT devices such as sensors, motors, transmitters, etc. monitor and transmit large amounts of data and a large number of requests, Node.js is great for handling them. Node.js environment has an excellent SDK for efficiently processing multiple data streams which improves the app’s and server’s ability to manage large amounts of requests simultaneously. 

Chats, Social Networks, and Chatbots 

As we’ve already mentioned, Node.js is good for apps that transfer real-time messages from one source to another in whatever format you can come up with: video chats, text, or voice messages. 

Asynchronous request handling helps Node.js-based apps ensure high performance and robustness of communication, which are a must for solutions like Twitter or Telegram. 

Gaming Apps

Online games with real-time multiplayer will also benefit from Node.js a lot. The server-side platform on which they are based must provide a very high response time to user actions and low latency. Node.js meets these requirements.

If you aim to build an app that handles real-time work with data and is supposed to be fast, then you should hire Node.js programmers. 

Now, more on whether or not Node.js should be used for other tasks. 

Note, that, for many of these tasks — CMS development and projects that require quick development, for instance, — skilled developers can utilize Node.js successfully. You can use Node.js for games, — in fact, that’s one of the most popular backend technologies for them. The issue is that large games are better off with other technologies. Above is a table for what programming languages allow to do the job most efficiently.
