In the dynamic world of web development, hiring dedicated Node.js developers is becoming an increasingly popular choice for businesses. This article delves into the reasons why Node.js has become the go-to framework for modern enterprise-level web development and why you should consider hiring a Node.js development company for your business’s backend needs.
The Rising Popularity of Node.js
Node.js, a server-side platform built on the JavaScript engine of Google Chrome, has been growing in popularity since its inception by Ryan Dahl in 2009. This open-source runtime environment allows for the development of server-side and networking applications with JavaScript, and it is compatible with OS X, Microsoft Windows, and Linux.
As a cross-platform runtime environment, Node.js offers a vast library of JavaScript modules, simplifying the development of Node.js web applications. This has resulted in Node.js being used by many renowned companies, including Netflix, Uber, and PayPal. In fact, according to StackOverflow’s 2021 Developer Survey, Node.js ranks as the 6th most popular technology among programmers.
Node.js: An Asset for Both Frontend and Backend
Contrary to common misconceptions, Node.js is not solely a backend framework for constructing servers. Its event-driven, non-blocking nature makes it a preferred choice for developers seeking a flexible and scalable backend. However, Node.js can also be effectively used on the frontend. Here’s why:
Code Reusability
JavaScript is a common language for writing both backend and frontend code, especially with the support of frameworks like Express.js and Meteor.js. This makes Node.js versatile, as many components can be reused between the frontend and the backend, enhancing productivity and efficiency.
Developer Efficiency
Node.js allows developers to work with a single language for both backend and frontend, thus saving significant time by reducing context switching between multiple languages.
Vibrant Community
The presence of an active online community greatly influences the speed of a successful development cycle. The Node.js community is active and engaged, frequently providing solutions to common problems on platforms like Stack Overflow.
Node.js Frameworks
Despite its versatility, certain tasks may still be difficult to accomplish with Node.js. Therefore, several frameworks have been developed to aid developers:
- Nest.js – A robust Node.js backend framework suitable for enterprise-level projects, offering a large number of libraries that implement Typescript, Model-View-Presenter (MVP), and integrated Object-Oriented-Programming (OOP), Function-Point (FP), and Functional-Reactive-Programming (FRP) principles.
- Express.js – A lightweight, minimally designed framework with a large set of HTTP helpers, ideal for developers who require a fast and cost-effective development process. It’s perfect for creating APIs, mobile apps, and web applications.
- Socket.io – Known for its user-friendliness across various platforms, Socket.io primarily focuses on bi-directional real-time connectivity. It also supports reconnection, binary, and multiplexing.
- Meteor.js – Provides real-time functionality, dynamic imports, front-end-back-end connectivity, and API protection.
- Koa.js – Uses asynchronous methods to simplify error handling and enhance the application’s performance.
- Loopback.io – Enables quick API creation by offering a variety of features that simplify the process. It supports ad-hoc queries, storage services, a variety of REST services, and numerous popular databases.
The Purpose of Node.js
Node.js is known for its speed. It provides event-driven two-way connections between the client and the server, enabling both parties to initiate communication and data exchange. Its unique I/O approach makes it excel in scalable and real-time situations that are increasingly demanded from our web servers.
Additionally, Node.js is fast and lightweight, and its ability to use JavaScript code on both the frontend and backend opens up new development possibilities. This frontend and backend flexibility significantly enhances the efficiency of the developer community, reducing development costs.
Node.js Versus Web JavaScript
While JavaScript is a scripting language that can be used in web browsers, Node.js is a JavaScript interpreter or execution environment complete with numerous necessary libraries and components. While JavaScript is a single defining programming language that can operate in any browser, Node.js is an interpreter or environment that can represent JavaScript and run any JavaScript program.
The Advantages of Using Node.js for Backend Development
According to the Node.js 2018 User Survey, over 85% of respondents use Javascript runtime in their web apps. Node.js’ average usage consistency has spanned more than two years, giving it an edge over its competitors.
High Performance for Real-time Applications
Node.js-based web apps have a significant advantage in their ability to multitask. Its single-threaded, event-driven architecture effectively processes multiple concurrent requests without clogging RAM. In addition, its event-loop and non-blocking I/O operations allow for fast execution of code, significantly impacting the overall performance of the application.
Easy Scalability for Modern Applications
Node.js features a cluster module that enables load balancing across multiple CPU cores. It uses a non-blocking event-loop system that provides excellent scalability and allows the server to respond to requests quickly.
Community Support
The Node.js community, with millions of active developers, provides significant help to developers worldwide, even for the most unusual development challenges.
Cross-Functional Teams
Node.js supports full-stack development, allowing for the creation of a team focused on improving the development life cycle and quickly responding to issues. This environment promotes high productivity and efficient problem resolution.
Improved App Response Time and Performance
Node.js’ single-threaded event-loop paradigm provides a non-blocking asynchronous architecture. This improves the responsiveness of your application by allowing it to handle multiple concurrent users.
The Drawbacks of Node.js for Backend Development
Despite its numerous advantages, Node.js does have some drawbacks:
Unstable API
The Node.js API frequently changes, and these changes are often incompatible with previous versions. When this happens, developers are forced to modify the old code base to make it compatible with the new version.
Reduced Performance for Heavy Computing Tasks
When Node.js receives a large CPU-driven task, it utilizes all of its CPU power to complete the task, slowing down the event loop and obstructing the user interface of our application.
Asynchronous Programming Model
The asynchronous nature of Node.js makes it difficult to maintain code. This can lead to what is often referred to as “callback hell”, which can affect the performance and quality of the code.
High Demand With Few Experienced Node.js Developers
The demand for experienced Node.js developers is high, but the supply is low. This mismatch can make it challenging for businesses to hire dedicated Node.js developers.
System Crashing
If an exception reaches the core of the event loop, the entire application may crash, with no way of recovering the user session state before the crash.
Getting Started with Node.js
Starting with Node.js is relatively straightforward. The official guide on the Node.js official site is the best place to start, covering all the fundamental principles. Once your server is up and running, you can explore various key Node.js frameworks and relational databases.
Why Node.js is Gaining Popularity
Node.js is a rapidly evolving environment poised to solve and minimize many of the development challenges that app teams may face. Its utility is expected to become clearer to many developers in the coming years. Many businesses have placed their trust in Node.js to build their applications, and they have already seen excellent results.
Conclusion
Node.js is a fantastic tool for creating scalable and high-performing web applications. It provides a perfect blend of performance, size, and speed, enabling use cases crucial to web projects. Your applications can benefit immensely from using Node.js.
