Developing web apps with Node.js

JavaScript is one of the most well known and widely used client side programming languages. Mostly, it is used as a web front-end development tool and proved to be more than a handy customer for the building of cross-development platforms. It also earned popularity because of its use in different platforms including React Native, PhoneGap, Titanium, Apache, NativeScript, Appcelerator and so forth.

The area of application for JavaScript has extended and now it is also used for server-side programming. Node.js has a significant role in this major shifting in the web development.

What is Node.js?

This is a runtime environment, based on Chrome’s V8 JavaScript engine. It helps in the execution of Javascript code server-side. This is an open–source cross-platform JavaScript that helps in the development of real-time network application. It offers event driven I/O APIs and asynchronous. It can also interpret JavaScript code by means of Google’s V8 JavaScript engine. Also, it works on a single threaded event based loop to make all executions non-blocking. You can’t consider Node.js as not a framework and it has nothing to do with the PHP, .NET or JAVA. Let us discuss the advantages and drawbacks of using the Node.js as server-side programming.

Pros of Node.js –

1. Node.js offers an Easy Scalability-

One of the major advantages of Node is that developers can easily the applications in horizon as well as vertical directions. The applications can be scaled in horizontal manner with extra nodes to the existing system. Additionally, it also offers you the choice of adding extra resources to the single nodes during the vertical scaling of the application. Hence, it is more scalable and provides better option than other JavaScript servers.

2. Easy to Learn-

Since JavaScript is one of the most popular programming languages, most of the front-end developers have a good grasp over it. It turns out to be a lot simpler for them to start using the Node.js at the backend. It is simpler to learn Node.js and consumes less time to work with it.

3. Node.js is used as a Single Programming Language-

Node.js offers the developers the advantage of writing the server-side applications in JavaScript. This allows the Node.js developers to write both the front-end and the back-end web applications in JavaScript using a runtime environment. Also, they don’t have to use some other server-side programming language. It makes the web applications deployment more simple because most of the web browsers support JavaScript.

4. High performance-

Node.js interprets the JavaScript code through Google’s V8 JavaScript engine. This engine compiles the JavaScript code directly into the machine code. This makes it simpler and faster to execute the code in a successful way. The speed of the code execution also enhanced by runtime environment as it supports the non-blocking I/O operations.

5. Strong corporate support-

The development of Node.js was supported by Joyent. In 2015, the Node.js Foundation was created to “enable far reaching adoption and help rapid development of Node.js.” IBM, Microsoft, PayPal, Fidelity, and SAP turned into the founding members of the organization. The list of associations utilizing Node.js in production is continually growing. It includes near about 300 surely well-known organizations, for example, PayPal, Medium, Trello, Uber, and Zendesk. Some open source projects have ever delighted in such strong support from the world’s leading companies. And, that predicts Node.js has extraordinary potential.

6. Handles the Requests Simultaneously-

Since the Node.js provides the option of non-blocking I/O systems, it generally helps you to process several requests simultaneously. The system can deal with the concurrent request handling effectively better than others including Ruby or Python. The incoming requests get lined up and are executed rapidly and efficiently.

7. Node.js is Highly Extensible-

The Node.js is known to be highly extensible, which implies that you can customize and then extend Node.js according to their prerequisites. You can use JSON to provide the scope for data exchange between the web server and the client. It is done with built-in APIs for developing HTTP, TCP, and DNS and so forth servers.

Cons of developing web apps with Node.js-

1. Application Programming Interface (API) is Not Stable-

One major issue that many developers experience is the Application Programming Interface (API) continues changing at frequent intervals and doesn’t stay stable. At times, another API appears having various drawbacks incompatible changes. Therefore the developers are forced to make changes in the available code bases to coordinate the compatibility with the latest version of the Node.js API.

2. Does not have a Strong Library Support System-

The JavaScript doesn’t have a well equipped and robust library system in comparison with other programming languages. The outcome is that the users are compelled to take the support of common library for executing different tasks, for example, Object-Relational Mapping (ORM), processing of the images, dealing with database operations, and XML parsing and so on.

This makes it challenging for the developers to implement the common  programming tasks using Node.js.

3. Asynchronous Programming Model-

If you need to make the applications highly scalable, the vital requisite is adoption of the asynchronous programming model. Numerous developers may find this programming model as highly difficult in comparison with the linear blocking I/O programming. Another con of the asynchronous programming is the codes will in general become bulky and the software developers need to rely upon the nested calls.

Final Words-

The Node.js is highly beneficial to the developers as compared to its disadvantages. What’s more significant is the way that it has extended the area of JavaScript application and can be used for both front-end and  backend servers. With the progress of time, more business organizations have adopted it and have ended with getting positive results.
