Node.js for web application development

The emerging startups, in most cases, are faced with a lot of obstacles – the primary one being scaling up, which again is consequent upon a number of other problems that are left unaddressed. The most common problems of all include synchronization, communication, and a fitting platform that should support and address all the needs. To address all such needs, an increasing number of startups is opting for Node.js for web application development.

Though originally Node.js was used by startups only for developing the front-end, it is now employed in back-end development as well. The startups also use this runtime environment in developing cross-platform mobile applications.

Why should you choose Node.js for web application development?

Having come into being in 2009, Node.js has already created a niche in the startups. A cross-platform, open source JavaScript runtime, Node.js comes packed with a complete bunch of features. Business giants all over the world are resorting to the use of Node.js for web application development. As it is that the runtime environment is built on JavaScript, the developers can create networking tools and web servers.

One of the strong points of Node.js is that you can run the applications on a wide variety of servers that include MAC OS X, Unix, Linux, and Microsoft Windows. Right from the inception of Node.js, it has been one of the favorites among the startups and enterprises because of the huge number of features that it assimilates.

In fact, few of the most eminent startups use Node.js for web application development. We will definitely come to that, but only after we have discussed its features.

I) It lets you share

Node.js enables sharing in the presence of NPM or Node Package Manager. The developers can create solutions effectively using Node.js, thanks to the repository containing 50,000 packages. The NPM being inbuilt, it lets the developers not just share and update but also reuse the codes as and when needed.

II) It’s fast

Node.js has a very high running speed, being built on the V8 JavaScript engine by Chrome. The coding runs fast, too. In fact, Node.js is a boon to the startups as it can make any framework run faster.

III) It becomes a proxy server too

The feature-rich Node.js allows you to use it as a proxy server too. It can be used for the streaming of data from a number of different sources. Node.js can be used as a proxy server in case a startup lacks the proxy infrastructure.

IV) Creates real-time apps

Node.js is employed in the making of chatting apps or gaming apps that call for a multi-user real-time experience. The process of synchronization is fast and serves the programs well that need event-based servers.

V) A community-friendly application

It wouldn’t be wrong to call this application a community-friendly one. Among all the other outstanding modules, the Socket.io is the most popular one dealing with the communication between the server and the client.

Compare Node.js with Groovy and Ruby on Rails

Now, that we are through with the features of Node.js for web application development, let’s list down a few of the big names that use Node.js:

  • Uber

With the headquarters at San Francisco, Uber is a leading transportation company popular globally. The company is operating in as many as 633 countries worldwide, covering 6 continents. It is a rather fresh startup, having been launched in 2012. It has almost replaced the traditional taxi, so much so that the latter has become a second preference.

What is important here is that Uber has chosen a platform that should help it run without delays. It has to coordinate the working between the partner-drivers and the riders while processing a lot of real-time information at a great pace. It is Node.js that helps Uber operate flawlessly.

  • Netflix

The biggest name in streaming media and on-demand-videos including television series and movies, Netflix, is roaring globally. Offering services in as many as 190 countries, Netflix expanded not just into television and film production, but also into online distribution apart from its own original programming in 2013. After a gap of 4 years, in 2017, the company had as good a number as 109 million subscribers globally.

From a fully-featured, stable application, Netflix wanted a lightweight and modular application with reduced complexities, leveraging the infrastructure too. Shifting to Node.js for web application development has been a historical decision in that they have been able to streamline development, cut down on build time, and increase the customization-level for the end-user.

  • eBay

One of the most popularly opted for online marketplaces, eBay offers both business-to-consumer and consumer-to-consumer services. The company is active and operating in as many as 37 countries worldwide.

Node.js addressed such problems like high traffic and scalability while maintaining live connections with the server and handling the I/O bound operations.
