Node js has been witnessing exponential growth in popularity over the last few years, and it is known as one of the hottest languages to be used in web development. Popular majorly because of Node js uses, this is the language to watch out for in 2022.
1. Asynchronous and Event-Driven
One of the unique features of Node JS is that all APIs of the Node.js library are asynchronous, that is, non-blocking. It essentially means Node.js is based on a server not dependent on an API to serve back the data.
The server moves straight to the following API, and a notification mechanism of Events of Node.js allows the server to track responses from the previous API call.
2. Single-Threaded but Highly Scalable
Another feature is that Node js uses a single-threaded model with an event loop. This can serve a much larger number of requests than Apache HTTP Server, traditionally provided by traditional servers with limited threads.
A single-threaded program can handle multiple requests, while each request blocks the thread. The event mechanism of Node JS allows the server to respond in a non-blocking way, meaning that the server doesn’t stop any lines.
3. Fast and Efficient
Node.js is lightweight and efficient as Node js uses an event-driven and non-blocking model. This feature of Node JS allows applications to run faster and more efficiently.
Making it the ideal choice for developing data-intensive real-time applications that operate in distributed environments.
Node JS is a preferred choice for business because of the following reasons:
1. Node JS Supports Caching
Node JS has caching enabled by default which means that when you require something once it caches in memory, the next time you request for it, it will be retrieved from the cache, not from the disk or database, which saves lots of time in such cases hence making application execution faster.
2. Simplified Web Development
1. Streaming Data
One of the most important advantages of Node js is its ability to handle a large number of concurrent connections with high throughput, which makes it a perfect application of node js that rely on real-time, bi-directional communication between clients and servers, like chats and online games.
The operating system buffers the data in memory and then sends another request for additional data. In this way, streaming becomes possible because it eliminates unnecessary data copying.
2. Real-Time Chats
Application of node js is widely used for real-time chat applications, another significant advantage of node js. It can perform the job of a real-time chat application with Socket.io, which uses web sockets to facilitate instant data transfer.
For this purpose, Socket.io functions together with Node.js and Express.js frameworks to allow you to develop websites and apps that can run in real-time and process many requests at the same time without reducing speed or performance.
3. Single Page Apps
Single-page applications (SPA) are web apps that load a single HTML page and dynamically update the page as the user interacts with it. Think of Gmail, Facebook, Google Drive, etc.
These sites don’t reload each time you click on something. SPAs give high performance and excellent user experience, but there are other benefits and node js uses:
4. Collaborative Tools and IDEs
The key advantages of node js are the collaborative tools and IDEs that have gained popularity in the past few years, especially among web developers. Node.js is used to build these collaborative tools and IDEs because it can efficiently manage multiple client requests.
Node js uses can be seen in web application development because it offers efficient modules that enable faster development of applications, and therefore companies prefer the application of node js.
The popularity of node JS is also used because it’s easy to build microservices. This is a new approach to building web applications, and it’s becoming more and more popular.
Microservice architecture revolves around developing small programs and services that can communicate and do their own tasks.
These are written in different programming languages and can be developed by other teams at the same time – this makes them more flexible than monolithic apps (written in one language). Microservices are faster and easier to develop, maintain, update, scale or change the technology stack.
6. I/O Bound Applications
Now that we know what an I/O bound application is, let’s look at how the advantages of node js can help you build one.
Consider a server in which many users are trying to access a large database. Here the database engine would be CPU intensive, while the server itself will be I/O bound as it is waiting for responses from the database engine.
On this kind of platform, Node.js would be ideal because its non-blocking nature will ensure that other requests do not have to wait for the first request to finish being serviced before being processed themselves.
7. Node JS uses as a proxy server.
A proxy server is a software that acts as an intermediary between an endpoint device and another server from where a user or client is requesting a service.
When the client lacks direct access to the server, it has to go through a proxy server that may be able to make requests on behalf of the client.
There are several different types of proxies used today. Including the following:
8. Data-Intensive Real-time Applications (DIRT)
DIRT is a buzzword that means applications with high data throughput (lots of reading and writing) that must update all their users in real-time. In the past, specks of DIRT were built using technologies like Ruby on Rails or PHP, but Node.js servers can handle twice as many simultaneous connections as their rivals because it uses non-blocking I/O and an event loop instead of threads.
Some popular examples of specks of DIRT are chat rooms, online gaming, stock trading software, and back ends for mobile apps.
9. The Internet of Things (IoT)
Node.js also provides an opportunity to build small, connected, and embedded devices. It can be used to connect embedded systems and sensors, so you are able to get more insight from the physical world.
It is highly scalable with a high performance and lightweight framework that processes asynchronous and event-driven I/O applications.
This means it can provide a single programming language for both the front-end and backend, reducing development time and improving productivity.
10. Single Code Base for Multiple Platforms
You can save cost and time on cross-platform development by choosing Node.js for your backend. It’s no secret that mobile apps are far more popular than their desktop counterparts, and many businesses are seeing a massive demand for the same application on multiple platforms. However, they find it hard to build their app once and run it everywhere.
The solution to this problem is code reuse using cross-platform technologies like React Native and Cordova. These technologies allow you to write once and run anywhere (WORA). But what happens when you need a server?
You don’t have time or money to hire expensive developers who specialise in different languages/frameworks based on the platform of your choice. With Node js uses in place, you can create a single code base that works across multiple platforms with minimal changes and effort from the developer’s end.
These popular node js uses have given rise to node js development services across the world. A Leading Node JS development company can handle any project by following an agile approach, from simple CMS-based websites to complex management software.
