As a business decision maker, you might not care as to which programming language or framework is used to develop your website or mobile app and how it works. What you care about is good performance, and that is exactly what Node.js gives you and why you need to know about it.
Node.js – a brief history
Why businesses are adopting it
The event-driven, non-blocking I/O model of Node.js makes it lightweight and efficient, and perfect for handling data-intensive real-time applications that run across distributed devices.
Node.js also makes a much smaller footprint on your web server. It allocates web server resources on an as-needed basis, not pre-allocating a large chunk of resources for each user. This means that Node.js can give you good performance while using fewer servers compared to other frameworks.
Applications created with Node.js are capable of handling a high number of simultaneous connections and can save enterprises operating costs on infrastructure.
Developer support for Node.js
Businesses are often hesitant about adopting open source projects since there is a misconception that there won’t be enough modules to extend its functionality and also security concerns.
On www.node-modules.com there are 181,486 modules available as of writing this blog post. This means that the programmers can easily and quickly build applications using code that is “off-the-shelf”, instead of re-inventing the wheel.
The way Node.js works can also be understood by the restaurant analogy given below.
Application areas for Node.js
Node.js is great for many things, but it’s not a one-size-fits-all technology. There are some things that it excels at and others where different technologies should be used. These are the things that you should be using Node.js for –
- eCommerce websites
- Enterprise web services
- Payment processing websites
- Networked multilayer games
- Social media apps such as chat tools
- Real-time services such as stock-trading sites
- Applications for Internet of Things devices and services
Real world examples of Node.js
LinkedIn – The company is one of the earliest adopters of Node.js and uses it to power its entire mobile software stack. The result – the number of servers used were reduced from 30 to just 3 and the system saw improved speeds of up to 20 times the previous performance.
GroupOn – Node.js is used for its back-end services and has reportedly improved page load times up to 50% faster than before.
Walmart – Used Node.js to handle all its mobile traffic on Black Friday 2013.
Microsoft – The tech giant wants Windows 10 to play a big part in the IoT industry and is bringing Node.js to the IoT Core Edition of Windows 10.
