What is Node.js?

Node.js is a large open-source server-side, Javascript-based runtime environment. The single-threaded method utilised for web loading and async programming is credited with the framework's success as a high-performance, scalable framework.

Furthermore, Node.js-based frameworks like Express, Socket.io, and Meteor.js can be used to improve a project's backend functionality. The technology is renowned for building single-page apps, websites, and backend API services using real-time and push-based architectures.

Node.js features

• Built on Chrome’s V8, an engine for chromium browsers
• Run-time platform
• Uses a non-blocking, event-driven I/O model
• Follows a single-threaded model
• Highly scalable and lightweight 
• Efficient for processing multiple requests with less CPU usage
• Thousands of libraries and tools for JavaScript are gathered on npm (a default Node.js package manager and marketplace)

What is Express? 

Express.js, sometimes known as Express, is a Node.js-based open-source server-side framework. It is part of the MEAN, MEVN, and MERN stacks and is written in Javascript.

For speedier and more efficient web development, Express includes plugins, template code, middleware packages, and routing features. In addition, the framework allows third-party libraries and functionality to be included, making customisation easy. Express js tutorials help you to get high knowledge on that.

Advantages of express js vs Node.js

For Node js

Simple to Learn

Because JavaScript is one of the most well-known programming languages, the majority of front-end developers have a good understanding of it.

The usage of Node.js in the backend becomes quite simple for developers. Node.js is easier to learn and takes less time to master.

Better Performance

Node.js uses Google's V8 JavaScript engine to parse JavaScript code. The major benefit of this method is that it compiles JavaScript code straight into machine code, making it easier to implement the code efficiently.

Non-blocking operations are supported by Node.js, which improves the speed of code execution.

Cache

The open-source community of Node.js offers the ability to cache specific modules. Any module request is cached in the application memory.

Because caching helps apps to load web pages faster and reply swiftly, developers don't have to re-execute the scripts.

Freedom

Node.js provides developers the freedom to create apps and software. This functionality is very useful because other platforms have limits and do not have it. When creating apps using Node.js, you may start from the ground up.

Extended Support for Tools

Another benefit of Node.js is that it provides support for a variety of widely used tools. On Node.js, you can easily use the standard tools.

If you wish to test the source code, for example, you can use any unit-testing tool like Jasmine.

Node js is required in angular Js. For that node js has to be installed.

Extensible

Node.js is recognised for being extremely expandable, which means that you may customise and expand it to meet your specific needs.

You may also use JSON to specify the level of data exchange between the web server and the client. It also comes with built-in APIs for constructing HTTP, TCP, DNS, and other types of servers.

Scalability

One of the main advantages of Node.js is that designers believe it is straightforward to grow apps both horizontally and vertically. By adding more hubs to the present architecture, the applications may be scaled evenly.

Furthermore, during the vertical scaling of the application, Node.js gives you the option of adding extra resources to the single hubs. As a result, it is extremely flexible and provides superior alternatives to other JavaScript servers.

Advantages of Express.js

• With Express, creating apps with Node.js becomes simple, quick, and improved.
• The Express.js framework is extremely easy to adapt and customise to meet a variety of needs.
• Express.js provides for compatibility with a variety of template engines, including Jade, Vash, and EJS.
• The development of a REST API server is the most intriguing feature of creating an app with Express.js.
• Express.js makes serving your app's static files and resources a breeze.
• Express.js has the largest Node.js community of all the frameworks available. It has the most advanced framework of the three Node.js frameworks available.
• Databases like Redis, MySQL, and MongoDB are simple to connect to.

Limitations of Node.js

API is Not Stable

The Application Programming Interface (API) in Node.js is changing at regular intervals and does not stay stable, which is one of the major issues that many designers confront.

Frequently, another API appears with different incongruent modifications in reverse. As a result, the developers are forced to make changes to the existing codebases in order to maintain compatibility with the most recent Node.js API adaptation.

No Strong Library Support System

JavaScript does not have a robust library system when compared to other languages. This forces users to utilise a common library to complete activities such as ORM, database operations, image processing, and XML parsing, among others.

This makes it difficult for developers to use Node.js for even basic programming tasks.

Asynchronous Programming Model

In comparison to linear blocking I/O programming, many developers find this programming style more difficult. The codes get clumsier in asynchronous programming, and developers must rely on nested calls.

Node.js offers both benefits and drawbacks. The key point to consider is that Node.js has broadened the scope of JavaScript applications and may be used for both backend and frontend servers.

Limitations

The majority of the system's restrictions are, to a large part, emotional in character. Some people dislike Express's simplicity, while others complain about the chance for action rather than a conventional structural design. Despite all of these flaws, the system's viability is difficult to achieve.

For big projects, Express.js is not a good solution. This framework works well for small and medium-sized applications.

In Express, there is no built-in error management. It's also extremely opinionated, which can be both a good and negative thing. For the most part, it may be detrimental to novices.

Popular apps using Node.js as backend technology

• NASA discovered that Node.js made data migration from traditional databases to cloud databases a breeze. It combined all queries into a single database, slashing access time by 300 percent.

• Twitter introduced Twitter Lite, which has a 30 percent quicker startup time and loads quickly on poor connections.
• Netflix's starting times have been cut in half, and its performance has improved dramatically. They switched from Java to Node.js for their backend, which reduced startup time from 40 minutes to 60 seconds.
