What is Node.js?
Here are a few advantages of using Node.js:
- Js is an open-source framework with an MIT license.
- It is a compact framework with only enough modules. Other modules may be added based on the requirements of an application.
- Applications are written in js and never buffered any data. Node.js applications output data in chunks.
- There are no blocking or synchronous APIs in the Node.js library. It implies that Node.js servers never have to wait for data to return from an API. After gaining access to an API, a Node.js notification mechanism enables the server to wait for the response to one API request before going on to the next.
What are the attractive features offered by Node.js?
- Easy to learn: Starting up with Node.js is simple. It’s a popular option for those new to web development. Thanks to the large community and plethora of instructions, starting is quite simple.
- Multi-Platform: Developers can create SaaS websites, desktop applications, and mobile applications with Node.js.
- Packages: There are several open-source Node.js packages available that can simplify your work. The NPM ecosystem presently has more than a million packages.
- Scalable: It offers huge application scalability. Node.js is single-threaded, allowing it to manage multiple connections at once.
- Speed: Non-blocking thread execution makes Node.js even quicker and more efficient.
- Strong Backend: Node.js is speedy and has capabilities like networking support because it is written in C and C++.
What is Node js used for?
It is possible to construct single-player and multiplayer games that run entirely within the browser without downloading any third-party plugins by integrating Node.js with tools like HTML5 and Socket.IO. Game creators may be better able to control the complexity of online games with the aid of several tools provided by Node.js, such as EventEmitter, which can be used to raise and handle custom events.
Real-time applications, or RTAs, are widely created with Node.js. Node.js developers find it much simpler to reach the performance customers expect from contemporary real-time apps thanks to its asynchronous, event-driven architecture, enabling it to manage input-output activities. The Socket.IO package is frequently used to build chat apps with Node.js because it offers real-time, bidirectional, and event-based communication between the browser and the server. Socket.IO may be used to build a group chat application in about 30 lines of written code.
One of the biggest media service providers in the world, especially when your job requires you to stream content to more than 150 million people throughout the globe. Because of this, enormous companies recently switched most of their API to Node.js. For both server-side and browser-side apps, Node.js functions as a universal language. It benefits from Node.js’s asynchronous, non-blocking I/O characteristics, making real-time and streaming operations incredibly straightforward and efficient.
- It is an open-source, flexible, rapid, and small framework.
- It is possible to cross-compile.
- Support for classes, modules, and interfaces is provided.
- It is used for both frontend and backend development so that it can run on various devices.
- It allows us to create user interfaces that respond as soon as a user moves the mouse over them.
- Server Load: The workload on the website server is reduced through client-side processing.
