Which applications are best suited for NodeJS?

Being a JavaScript runtime environment, it massively supports handling various events in a single thread and non-blocking I/O, resulting in the development of fast, efficient, and scalable applications while handling I/O-heavy workloads in web applications.

Below are the applications that NodeJS can develop:

1. Real-Time Chats

Real-time chat applications are online communication tools that enable the instant transmission of audio messages, text, and videos to the receiver from the sender.

Social media applications or commercial websites are renowned examples of it.

NodeJS comprises the essential features that are required to develop complex or large real-time chat applications as it has a powerful API that aids the creation of emitters.

The emitters emit named events, making it easier to implement and execute on the server-side events and send push notifications. It’s received by the event handlers.

These push notifications are also used in messaging and real-time chats.

2. Complex SPAs

Single-page applications are known in web development as the applications that fit on a single page to deliver a seamless user experience.

It helps to develop social networking applications, text tools, and online drawing tools. For instance, Gmail is the best example of a single-page application that has a great presentation and consistently updates incoming mail.

NodeJS is an ideal choice for developing SPAs due to its capability to handle data-heavy workloads and asynchronous calls that are a must in complex SPAs.

 In addition, the event loop in it can also delay various concurrent client requests while ensuring seamless data updates and easy transitions between the views.

Also, NodeJS is written in JavaScript, which is the same language in most in-demand JavaScript frameworks that are used for the development of various SPAs.

The browsers and NodeJS use JavaScript, which reduces the context switching. It also enables developers to use the same language structure and data on both the client and server sides, resulting in faster development and easier maintenance of applications.

It also makes it popular and a go-to tool for developing applications. In fact, the leading platforms, such as Medium and LinkedIn, have used it.

3. IoT

The Internet of Things is a network of devices that transmit and exchange data, such as actuators, and sensors. It also includes millions of devices, making it a tad tedious to manage tons of requests and data streams.

NodeJS has been used by most organizations and enterprises since its launch due to its ability to handle multiple requests and events efficiently, which are emitted by millions of devices while ensuring high performance.

The asynchronous processing and event-driven architecture in NodeJS enhance its ability to handle tons of data and requests from various IoT devices without compromising on its performance.

It also makes it a layer between the databases and devices in the application that can store the data.

4. Streaming applications

Streaming applications enable part of an application to be downloaded on demand without overloading the server.

Initially, the parts of the application needed for bootstrapping are downloaded, and later the rest can be downloaded in the background. Once the entire application is downloaded, it can be used with any network connection.

NodeJS has a native stream that is excellent for developing streaming applications. It’s got a writable and readable stream interface, which can effectively be monitored and processed.

The stream instances are also like Unix pipes in which half the part of an application enables executable code. It’s then further transmitted to the machine. Once it’s done, the connections are formed for new components which can be downloaded on demand.

5. Real-Time Collaboration tools

Real-time collaboration tools involve video conferencing, audio conferencing, project management, co-browsing, collaborative document editing, application sharing, and many more. Some of the prominent examples of it are Google Docs, Trello, and Slack.

Its event-based architecture and asynchronous nature make it a perfect choice for developing real-time collaborative tools.

Most requests and events occur instantly and simultaneously with these tools. For instance, various users can edit comments, posts, or paragraphs and can even attach media while operating it from different devices.

The changes can be done on any piece of content and can be implemented after a series of events that are indirectly dependent on the last event.

NodeJS instantly updates the collaborative environment with a push notification to the client. It ensures that the users have a coherent and single representation of the application.

The company preferably uses NodeJS for its ability to instantly propagate or handle multiple updates and have a huge number of open connections due to its outstanding non-blocking and event-driven architecture.

6. Developing micro-service architecture

Most applications that were once monolithic applications have transformed into micro-services.

Some of the best examples are Facebook, Netflix, Amazon, and eBay, making the micro-service architecture highly in demand.

NodeJS can create micro-services and APIs to better connect. The NodeJS repository involves Koa and the Express framework, making it simple and easier to initiate multiple server cases and designs while routing addresses.

One of the renowned examples is PayPal, which has used NodeJS for its micro-service architecture and has successfully utilized its benefits.
