Top 5 Reasons Node.js Popularity for Web Application Development

Node.Js provides platform for developers to write JavaScript on both client side and the server side. It means that you can use the same libraries for both back-end and front-end development. It helps to increase productivity of developers and also saves lot of time. 
Back end development becomes tough task for developers when it comes to developing a solution that is user-friendly and comprehensive across multiple platforms, distribution network, devices and browsers. Fortunately, Node.JS exists. That’s the reason, companies look for full-stack developers and more developers leverage existing skill sets for back-end server coding. Because, Node.Js provides platform for developers to write JavaScript on both client side and the server side. It means that you can use the same libraries for both back-end and front-end development. It helps to increase productivity of developers and also saves lot of time. 
Web application development in Node.js is not only a best option for developers but also for businesses. The five main reasons:
It works Fast: Node.js is built on chrome’s V8 JavaScript engine. V8 has ability to compile and execute JavaScript at lightning fast speed, because it compiles JavaScript into a native machine code, instead of interpreting it or executing it as bytecode.
Thus, accessing file system, database and network is very fast in node. By using Node.js, developers can build fast and highly scalable network applications which are capable of handling bulk amount of simultaneous connections having high throughput.
JavaScript is Everywhere: One of the biggest reason that make node.js so popular is that it uses JavaScript as its main language to build the web application. JavaScript is only choice to develop web applications in the browser. With node.js, JavaScript has also revolutionized on the server. The language is well versed with most of the developers, and is certainly driving the world today.
It is Lightweight:  Node.js operates on single thread, uses and event-driven and non-blocking I/O approach. Single thread uses to handle multiple concurrent requests. Node.js does not wait for any read and write operations, it always accepts request directly. This feature makes it lightweight and efficient to support hundreds of thousands of concurrent requests.
High Performance:  Many big brands like PayPal, Walmart, LinkedIn moved to Node.js because of its high performance capability. In 2013, Walmart put all their mobile traffic via node.js on Black Friday, the busiest shopping time of the year. On that day
, Walmart server did not go over 1% CPU utilization and yet they deploy with 200 million users online.
Easy to Modify and Maintain: Building applications on Node.js is easy because it has large and active community that contributes many useful modules that can be easily included and used.

Web Design Fundamental

There are no objective standards for Web design, but that’s a shame. While novel and inventive interface design is to be encouraged, the bottom line for most sites is usability. When the design starts to intrude on usefulness, the decisions is easy – make it easy for the user. Without delving heavily into the programming nuts and bolts of design implementation, we offer the following modest proposals:
1. Use Consistent Navigation
Give the users consistent navigation throughout the site. The importance of this simple point can’t be overstated, as newbies invariably get lost. Moreover, you should try to accommodate users with old systems and users with disabilities. Some users disable java, and others use text only browsers, so provide text only nav buttons to accommodate all users (or provide an alternate site). The Ultimate Managed Hosting Platform

2. Provide a Site Map
Just plain common courtesy, if you ask me. When I am in a hurry, the last thing I want to do is dig through a hierarchical Web site structure to search for something that I know exists on the site.

3. Provide a Contacts Page
You would be amazed at how many companies have ZERO contact information on their Web sites. Moreover, a generic e-mail link is NOT sufficient; you need to give people addresses, phone numbers, etc. In order for the Web to deliver on its promise, it must be used to increase the transparency of organizations.

4. Listen to the Users
Give your users a method for providing feedback. It’s true, people rarely use the feedback option, but its also true they really hate it when they are not given the option. The usability of your feedback system is a key when problems strike; a good system eases tensions and a bad system escalates the tensions dramatically. (Do we need to point out that timely response to feedback forms is also a necessity?)

5. Build an Intuitive Interface
The Ideal Interface must meet two criteria: (1) Newbies must be confronted with an easy-to-learn consistent system while, (2) Experienced users should be able to navigate the site quickly – the design should not impede or interfere navigation by an experienced user who is familiar with the site.

6. Provide FAQs
If your site generates a lot of questions, has complex content systems, you should include an FAQ that provides answers to the most common issues. Trust us, this feature will save you AND your users time.

7. Strive for Compelling Content
O.K., so this isn’t exactly a true “design” point, it still must be mentioned: You must give users a reason to return.

8. Insist on Quick Access
Building a page that looks good and loads quickly is not the easiest of jobs. Add into the equation the labyrinthine nature of some of the connections between you and the Web page server, it is not surprising that page loading times vary wildly. Still there are things your designer can do. Try 15 Second Rule: If the page doesn’t load in 15 seconds, it is too big. Tell your Web team to decrease file sizes.

9. Strive for Simplicity
Make simple, common tasks easy to do. When long procedures are necessary for new users, meaningful shortcuts should be provided for experienced users.

10. Provide Feedback
A well-designed site should give users feedback in response to user input, errors, and changes in status. The information should be communicated simply ,with an indication of what options are available to the user.

11. Be Tolerant
The site should be tolerant of errors and unusual usage. Beta testing of the site should encompass anticipating a wide variety of erroneous or atypical user behaviors. While it is probably impossible to anticipate all possible mis-uses, the site should handle mistakes with grace and, when possible, provide the user with guidance.
