What is Node.js used for?

The very first thing you have to know about NodeJS is that it’s not a framework that is javaScript.

NodeJS is a server-side runtime environment this is certainly built upon programming this is certainly event-driven that allows non-blocking I/O capabilities.

As a result of this excellent I/O model, building I/O-heavy and internet is certainly data-heavy and becomes very fast and effortless using NodeJS.

Aside from this, the capability of NodeJS to make use of JavaScript on both front-end along with back-end has also opened up many avenues being new web application development.

How Is It Different From Other JavaScript Frameworks?

Though there’s no distinction between NodeJS as well as other frameworks which can be javaScript terms of the program coding language made use of, why is NodeJS distinctive from all of those other JavaScript frameworks is its various sets of APIs.

For instance, unlike various other frameworks, javaScript NodeJS provides many APIs for backend development such as HTTP requests, channels, help for file systems, and son or daughter processes to name just a couple.

Also, since NodeJS utilizes JavaScript on both front-end as well as the end that is straight back it significantly advances the development speed.

To put it simply, NodeJS development permits companies and businesses to save lots more as NodeJS holds the ability to handle an extent that is the same with less horsepower.

Node JS Use Cases: When Is It Worth Using?

NodeJS, as stated before, provides a boost this is certainly great for the productivity of one’s group since it utilizes similar program writing language from the front-end and back-end.

The development process becomes even faster, more efficient, and cross-functional, which eventually contributes to lower development prices as a result.

However, it’s also worth mentioning that NodeJS is best suited for only a particular kind of web program.

Let’s discuss in detail Node this is certainly various JS instances to understand when is it worthwhile considering for web application development.

1 – When You’re Building Streaming Web Apps

Because of the Native Stream API, NodeJS can be an option that is excellent for establishing online streaming internet apps.

In inclusion, NodeJS also has a screen that is integral to readable streams that may be easily and effortlessly processed and administered.

These stream cases are nothing but Unix pipes which makes it possible to send parts of the application’s rule this is certainly executable to the local system while also maintaining a steady connection for brand new components to download as and when required.

Because of this, streams in NodeJS don’t require caching and saving temporary information as it offers an open link with the stream app’s data from the host to the local system.

The Native Stream API of NodeJS permits downloading only specific parts of the web application initially together with the remaining components installed in the history when required in layman’s terms.

2 – When You’re Building Real-time Collaboration Tools

Real-time collaboration resources are fundamentally Software solutions widely used for project management, co-browsing, sound and video clip conferencing, collaborative document modifying, and many other things.

In these solutions which are software, lots of I/O needs and activities occur concurrently. As an example, in a project administration solution, multiple users can compose remarks, upgrade status, and attach media to a project this is certainly certain.

Now, since NodeJS are capable of i/O that is heavy efficiently due to its WebSockets and Event API, NodeJS has turned into a preferred option among designers for building such real-time collaboration solutions.

Trello, as an example, adopted NodeJS for the event-driven design this is certainly non-blocking and straight away upgrades its collaborative environment.

3 – When You’re Building Complex, Single-Page Programs

Single-Page programs have grown to be a method this is certainly common.

In SPAs, the complete application is fit for a passing fancy page to present a desktop knowledge that is app-like.

NodeJS is just a fit that is perfect for building SPAs as it can effortlessly handle asynchronous calls and heavy I/O businesses.

In inclusion, NodeJS also works well with data-driven applications which can be single-page in which the server acts as the backend to transfer data to the customer, even though the client-side does all of the HTML renderings.

Finally, Since NodeJS and web browsers use the language that is the same javascript), the quantity of time for framework switching gets significantly paid down and developers may also utilize the same language structures and techniques in both the back-end and front-end.

This fundamentally leads to better maintainability and a quicker development period of your single-page application.

4 – When You’re Building Real-Time Chat Programs

These days while you might know, real-time chats are widely used everywhere on the net. In reality, they’ve sort of become a prerequisite, especially for commercial internet sites and products and services that are digital.

The news headlines this is certainly great, that NodeJS has most of the basic functionalities for building real-time chat apps. Node’s Event API enables designers to implement server-side occasions and press notifications, which are trusted generally in most chats and can be real-time.

In addition, the WebSockets in NodeJS also facilitate a change this is certainly a two-way an open connection, which is ideal for real-time talk application development.

For instance, you can put in WebSockets libraries like sockets.io or WebSocket-node to easily deploy real-time talk functionality.

In sockets.io Particularly, all you need to do is install the library on both server-side and client and create broadcasters and event emitters to push emails. The best component is, that this whole setup can be carried out with only a few lines of the signal.

5 – Whenever You’re Building Microservices Architecture

Microservices Architecture is a procedure for having a web application as a set of small, independent solutions for which each service plays a task that is unique to the company logic.

In the last few years, microservices design is now popular, specifically after the emergence of Amazon, Facebook, and Netflix.

Within this kind of web application, microservices generally communicate through REST/HTTP protocol with JSON information structure.

NodeJS is the technology this is certainly perfect to build such a microservices structure because NodeJS allows you to mount various cases of hosts for specific microservices and design appropriate routing details for all of them.

Furthermore, the lightweight character can considerably boost the scalability, maintainability, and efficiency of a web application.

These advantages had been very first leveraged by PayPal in 2013. PayPal utilized NodeJS to modularize its app bunch and split the development process into many microservices.

The consequence of NodeJS adoption helped the business to boost overall performance and significantly reduce its codebase.

Conclusion

NodeJS has become the number one choice among developers as well as companies for building modern web applications.

However, you should not use NodeJS if you’re developing a CPU-intensive web application as it may cause unresponsiveness due to its single-threaded nature.

On the other hand, NodeJS is the best choice if your web app involves dealing with heavy client-side rendering, frequent shuffling of data, multiple concurrent requests, and things alike.

That being said, if you’re planning to use NodeJS in your web application, hire Node JS Developer from Credencys to fully utilize the capabilities of Node JS.
