This article gives you a detailed analysis of the ten reasons why Node.js has become the best choice for web application development. Friends in need can refer to it.

When a disruptive technology enters the technology market, it always brings a shock, but is often followed by abandonment. However, this is certainly not the case with Node.js, which is an open source, cross-platform JavaScript runtime based on Chrome. Developed by Ryan Dahl in 2009, Node.js has now become a unique choice for real-time web application development, improving ROI by providing a highly interactive user experience.

The biggest advantage of using Node.js is that developers can write JavaScript on both the client and server sides. It is worth mentioning that companies like PayPal, Yahoo, eBay, Netflix, The Mail Online, and Walmart have implemented their respective businesses using Node.js. Continue reading below to know the top 10 reasons why most businesses choose Node.js for web app development.

The top ten reasons behind the surge in popularity of using Node.js for Web App development:

1. Speed ​​up development

Node.js uses the V8 engine developed by Google, which can compile JavaScript into native machine code and execute it quickly. Because Node.js uses an event-driven, non-blocking I/O model, it is efficient and lightweight for memory-intensive and data-intensive real-time web applications that can work on multiple devices.

Using Node.js, you can perform common web application tasks such as reading or writing to a database, reading or writing to a network connection, and reading or writing to the file system very quickly. Node.js is a boon for developers looking to build fast, powerful web applications that can efficiently handle parallel connections and increase throughput.

After LinkedIn selected Node.js, its mobile traffic increased significantly and the number of servers was reduced from 30 to 3. PayPal is another example that has benefited from Node.js. After using Node.js, PayPal's response time improved by 35%, processing double the requests per second compared to before. Node.js applications can run on multiple servers including Microsoft Windows, Mac OS X, and Unix.

2. Very suitable for real-time application development

Currently almost every company will use real-time Find user information. The simple reason for this is that reliable access to customer information provides a significant boost to business sales at the time it is generated, by giving users what they are actually looking for, rather than the randomness that interests them. And over the past few years, building real-time web apps using Node.js has become the best way to do it.

With Node.js, all worries about underlying sockets and protocols disappear. With Node.js, you can build a real-time web application as quickly as you can create a simple blog in PHP. Node.js is ideal for multi-user real-time web application scenarios, such as games and chat applications. Multi-user functionality is addressed by the event loop via the WebSocket protocol, which works over TCP. It also prevents excessive overhead of HTTP for web development.

3. Data flow

Although HTTP requests and responses are considered two isolated events, In fact they are data streams. The nice thing about Node.js is that it can do file processing while uploading. Therefore, a lot of time can be saved in the overall process where the data comes in the form of a stream. The same is the case with live video or audio.

4. Node.js is ubiquitous

JavaScript can be used in both browsers and servers. If a company needs to build logic for browser-side changes to move to the server-side, developers can easily do so by using Node.js code migration. Still, there's not much difference between writing code that runs in the browser or server-side.

5. Allows web applications to use a single code base

Using Node.js, developers can automatically send and synchronize data between the server and client as it allows developers to Server and client write JavaScript code. Meteor is a web application framework built on Node.js that provides support for the same code base for both client and server sides. Any data changes on the server are immediately displayed on the client.

"Node.js is not a new platform dominating the world of web development. Rather, it is a platform that meets specific needs," according to web engineering firm Toptal. Node.js really shines in building fast , scalable network applications.

6. Serving proxy servers

One of the biggest advantages of using Node.js is that it serves as a proxy server to serve services with different response times, or to serve services from multiple The origin collects data and provides services.

For better understanding consider the following example: An enterprise has a server-side application that communicates with third-party resources, collects data from different sources, or stores images and videos to third-party cloud services. Now, while enterprises can use dedicated servers, Node.js is a better choice when infrastructure is not present or when a solution is required for local development.

7. Powerful Node.js Package Manager (NPM)

Node.js has a dynamic repository of dynamic tools and modules that programmers can use to share application development. Node.js can be used with thousands of modules for various tasks such as file upload management, connecting to a MySQL database or Redis through frameworks, template systems, and real-time communication management with visitors.

For programmers who need to reuse code created by external JavaScript developers to solve a specific problem , the Node.js package manager or NPM is their savior. NPM also allows JavaScript developers to download updates to specific code previously used in their applications. Even if you don't want to reuse code created by JavaScript developers outside your organization, you can adopt a module-based approach to improve synergy between team members.

Using NPM, PayPal has significantly improved developer productivity. Additionally, the internet payments giant doesn’t need as many developers to build an app as it did before using Node.js.

8. Node.js is great for database queries

For database queries, Node.js has an advantage because JavaScript can be used to write database queries for new NoSQL databases like MongoDB, CouchDB, etc. This is a big relief for developers as they don’t need to remember syntax differences when performing the task of combining Node.js and NoSQL databases. Since the data format stored in JSON allows for smooth operation, there are no hitches in data conversion or mismatch. So Node.js is really a boon for real-time web applications.

9. Node.js hosting has reached a new level

Due to the popularity of Node.js among developers, its hosting has achieved a lot of success. PaaS (Platform as a Service) service providers such as Heroku and Modulus provide support for node deployment with a single command. With Node.js hosting, you can reduce page load times by up to 50% and reduce the number of servers required to host your application.

10. Thriving open source community

Node.js also has a very good community. Because of its open source community, Node.js provides many excellent modules that can add more excellent features to web applications. For example, Socket.io can be used to handle constant communication between clients and servers, allowing the server to send real-time updates to the client. Express.js, Koa.js, Hapi.js, Sails.js, Meteor, and Derby are some of the other top frameworks developed by the Node.js community to speed up the application development process.

The IoT community also welcomes the use of Node.js for embedded devices and robots such as Cylon and Nodebots. Moreover, it has become a giant in the world of real-time web APP development. All the advantages mentioned above about Node.js are the reasons why many companies consider Node.js to be a good technology for running heavy-load web applications and allow teams to use it in production environments.

The above is what I compiled for everyone. I hope it will be helpful to everyone in the future.
