Overview to Node Js
Pros Of Node Js
Asynchronous event-Driven I/O
It makes Node.JS very efficient at handling concurrent requests, as it does not have to wait for one finish before starting another.
It is lightweight, as only one thread has to be managed.
Its huge community provides endless support to Node.JS developers.
Wide Range Of Modules
Numerous modules are available for Node.JS, making it a versatile platform for building various applications
- Any CPU-intensive computation will block Node.js; therefore, using a threaded platform is preferable. Alternatively, you may scale the calculation out.
- Using Node.js with a relational database is still quite a pain (see below for more detail).
- Pick up any other environment, such as Rails, Django, Python., or Java MVC, if you want to try to perform relational operations.
Benefits of Node.js over other technology?
- The scalability provided.
- Node.js is light and fast.
- Many hosting providers are available.
- Highly extensible.
- Its caching ability.
- Node.js is simple to learn.
- The process of coding and development is easy to understand.
- It comes with caching capabilities.
- It is extensive.
Examples of Node.js Apps
Developers mainly prefer Node.JS for creating desktop and mobile apps that require seamless operations and large amounts of connections. In that context, many popular apps have switched to Node.JS after using other runtime environments.
It is the world’s leading streaming service, with over 150 million subscribers covering 190 countries. It offers ample films and series, including in-house production. Besides, when it comes to streaming enormous amounts of information to millions of users, Node.JS goes best! It has helped Netflix to go smoothly with massive traffic alone.
It is a popular social media platform that has 330 monthly active users. It is among one of the ten websites most visited in the world. Twitter switched to Node.JS, allowing it to make rapid changes and deploy faster. Moreover, it has helped the company to move quicker and scale easily.
It is a ride-hailing platform that is present internationally in 700 cities and 65 nations. Uber has served over 110 million users and has 3 million drivers. The reason for Uber to consider Node.JS is it makes the application more responsive and has real-time potential.
As a collaborative tool, it has dramatically facilitated seamless communication among individuals. Slack has more than 12 million active users that some leading companies like NASA, Airbnb, and eBay use. Slack uses Node.JS due to the event-based architecture function that makes it ideal for real-time applications.
How Does It Work?
Another thing that you may or may not have read about Node.js is that it is single-threaded.
Based on event-driven architecture, and non-blocking based on the I/O model.
Why is Node.js so popular?
1. The V8 libraries are built on an incredibly powerful virtual machine
Event-driven asynchronous callbacks.
To understand why Node.js applications have to be written this way, we need to understand how Node.js executes code. Node’s approach isn’t unique, but the underlying execution model is different from runtime environments like Python, Ruby, PHP, or Java.
3. NPM: The Node Package Manager
The idea of NPM modules is quite similar to that of Ruby Gems: a set of publicly available, reusable components, available through easy installation via an online repository, with version and dependency management.
A full list of packaged modules can be found on the NPM website or accessed using the NPM CLI tool that automatically gets installed with Node.js. The module ecosystem is open to all, and anyone can publish their module that will be listed in the NPM repository.
Some of the most popular NPM modules today are:
- express – Express.js, a Sinatra-inspired web development framework for Node.js, and the de-facto standard for the majority of Node.js benefits out there today.
- socket.io and sockjs – Server-side components of the two most common WebSockets components out there today.
- Jade – One of the popular templating engines, inspired by HAML, a default in Express.js.
- mongo and mongojs – MongoDB wrappers to provide the API for MongoDB object databases in Node.js.
- Redis – Redis client library.
- coffee-script – CoffeeScript compiler that allows developers to write their Node.js programs using Coffee.
Where Node.js Can Be Used?
- Server-side programming
- Mobile App Development
- Back-end API services
- Web application
Analyzing Node.js vs other programming languages
Of course, there are lots of different languages out there to choose from, and each one will bring something different to your project or application. To help you decide, we’ve put together a comparison of Node.js and some of the main alternatives available.
1. Node.js vs Python
Python is an object-oriented, high-level, interpreted programming language with a focus on readability and productivity. It was founded in 1991 and supports a number of programming paradigms, making it an excellent solution for a wide range of commercial operations. As a result, it is simple to use and create, with a large standard library and environment.
This makes Python perfect for CPU-intensive apps, which, as we’ve seen, aren’t a strong suit for Node.js. Python also has the upper hand when it comes to time-sensitive development and deployment options. You won’t need to look for numerous utility modules and packages for your application because it comes with a vast standard library and modules.
Instead, you can start working on the project right now.
In addition, Node’s power in handling heavy I/O operations and shuffling of data between the front end and the back end makes it the better choice for Single Page Applications and Real-Time Applications.
2. Node.js vs Java
Web apps, mobile apps, real-time applications (instant messaging, live chat), online gaming apps, e-commerce transaction software, and more can all benefit from Node.js.
It’s also a smart choice if you’re working with microservice architecture, which can serve as the foundation for more complex systems – remember, Node.js was used to create apps like Netflix and Uber.
Java, on the other hand, is ideal for CPU-intensive or CPU-bound applications. The same is true for programs with a large codebase: because Java uses tightly typed sources, refactoring and bug fixing will be easier during maintenance.
Java is a wonderful choice if your application employs an RDBMS (Relational Database Management System) since it offers capabilities that facilitate multi-database object-relational mapping.
Nodejs vs Other Technology Architecture?
Pros of Nodejs:
This eases development (including hiring) significantly.
Crawlers get a fully rendered HTML response, which is considerably more SEO-friendly than, say, a Single Page Application or a Node. js-based websockets app.
Cons of Nodejs:
Any CPU-intensive computation will block Node.js, therefore using a threaded platform is preferable. Alternatively, you may scale the computation out.
Using Node.js with a relational database is still quite a pain (see below for more detail).
Pick up any other environment, such as Rails, Django, Python., or Java MVC if you want to try to perform relational operations.
We already know that Node.js and other languages such as Python and Java have advantages and disadvantages and that they are utilized for various types of projects.
So, when deciding between Node.js and other languages like Python, Java, weigh.
All of the benefits and drawbacks to choosing which is ideal for your project application.
