Hiring the software development talent pool for an innovative IT project has been a challenge for big companies and start-ups. They have to explore the subject and deeply study IT companies’ cases, when looking for Node.js developers for hire.
Choosing a backend technology is one of the crucial tasks that every company must make when developing an app or software. Backend technology defines its development and maintenance cost, but also how fast the app could be delivered to the market.
What is exactly Node.js?
To put it in simple words, Node.js is a platform for running JS script outside the browser. Programmers can produce backend applications with Node.js.
Node JS is a perfect solution for the development of apps that require a continuous connection from the browser to the server. This solution is often used for real-time applications such as news feeds, chat, and push notifications.
Why it’s beneficial for software development? Well, Node.js has a feature 'require' similar to import when you are working with libraries in Java or Python or include in C++. So, when you require an external library, you can take only those functions that you need to use in your project.
Many frontend apps require several libraries, such as jQuery, Bootstrap, etc. When you import these scripts into your HTML file, your browser will download the entire library. And this will increase page load time, and affect the SEO of your website. However, this issue is partly resolved by using minified and cached files, and by deferring such scripts. With Node.js you can require specific functions and determine which parts of the libraries to integrate into the project. This feature squeezes the script size requested during the page load, and improves page speed score.
What Is Node.js Used For and How to Use it?
As this runtime environment is easy to learn for both, back-end and front-end developers, it went popular. Over the last couple of years, the area of usage for Node.js has expanded. It is used in blockchains, artificial intelligence, and machine learning projects.
In Node.js project, the database is used as a storage unit of the app. Accepting a request from the frontend server, the backend application searches the data in the database and sends back the response to the client’s browser.
JS developers also use Node.js in the front-end to automate coding tasks. Development tools, such as Gulp, Bower leverage capabilities of Node.js to enhance software development. Therefore, Node can become an added value for UI development as well.
Who uses Node.js?
On GitHub wiki, you can find a complete list of applications and companies which are using Node.js. Only to name the biggest ones: eBay, General Electric, GoDaddy, Microsoft, PayPal, Uber, Yahoo!
Netflix, the leading Internet television network, trusted its servers to Node. It uses lots of A/B testing to provide an enriched experience for the final users of its data-driven online platform.
Walmart, the world’s largest retailer, has been using Node.js for its mobile app. It allows Walmart to provide advanced features on the client-side. Uber has developed its complex matching system on Node as well.
PayPal, one of the leading fintech market players, has trusted its back-end development to Node JS. First, they were testing two applications, written on Java and Node.js. And the company learned that the Node.js app was much faster while it required 33% fewer lines of code.
Why Node.js is so popular?
The Node.js core is secure. It is also very lightweight as it uses an event-driven architecture and runs on a single thread. Node.js implies IDEs like Visual Studio, and the support for basic code editors like Sublime Text and Notepad++.
Besides, Node is supported by a document-based model of database, unlike common SQL databases that implement relational models. Such a database is convenient to use; you can host it anywhere on the cloud-based hosting providers.
