Why use Node.js for web application development

This time I will bring you why Node.js is used in web application development. What are the precautions for using Node.js in web application development? Here are practical cases. Let’s take a look. .

When a disruptive technology enters the technology market, it always brings a shock, but is often followed by abandonment. However, Node.js Of course this is not the case, it is an open source, cross-platform JavaScript runtime based on Chrome. Node.js by Ryan Dahl on Developed in 2009, the platform has now become a unique choice for real-time web application development, improving ROI by delivering 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, like PayPal, Yahoo, Companies like eBay, Netflix, The Mail Online, and Walmart are already using Node.js realized their respective businesses. Continue reading below to know the top 10 reasons why most businesses choose Node.js for web app development.

Top 10 reasons behind the surge in popularity of using Node.js for Web App development:

1. Speed ​​up development progress

Node.js uses the V8 engine developed by Google, which compiles JavaScript into native machine code and executes it quickly. Thanks to Node.js Uses an event-driven, non-blocking I/O model, making it 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 a 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 case that benefits from Node.js. PayPal's response time improved after using Node.js 35%, handling twice as many requests per second as before. Runs on multiple servers including Microsoft Windows, Mac OS X, and Unix Node.js application.

2. Ideal for real-time application development

Almost every company currently looks for user information in real time. 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, using Node.js has become the best way to build real-time web apps.

With Node.js, all worries about underlying sockets and protocols disappear. Using Node.js, you can do things like in PHP Build a real-time web application as quickly as you create a simple blog. Node.js is great 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 web development from Excessive overhead of HTTP.

3. Data flow

Although HTTP requests and responses are thought of as two isolated events, they are actually streams of data. The nice thing about Node.js is that it does

file handling

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 everywhere

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. Allow 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 write JavaScript for both server and client code. Meteor is built on Node.js for the web The application framework provides support for the same code base for both client and server. 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 company Toptal. The real highlight of Node.js is building fast, scalable web applications. .

6. Provide services for proxy servers

One of the biggest advantages of using Node.js is when it acts as a proxy server to serve services with varying response times, or to collect data from multiple origin points.

To better understand 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 into 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 features a dynamic repository of 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 uploadmanagement, 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 outside your organization Code created by JavaScript developers can also take 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 very suitable for database queries

For database queries, Node.js has an advantage as JavaScript can be used for new NoSQL like MongoDB, CouchDB etc. Database writing database queries. This is a big relief for developers as they perform combined Node.js and NoSQL There are no syntax differences to remember when working with databases. Since the data format stored in JSON allows for smooth operation, there are no hitches in data conversion or mismatch. So Node.js for real-time This is indeed a boon for web applications.

9. Node.js hosting has reached a new level

Since Node.js is so popular among developers, its hosting has achieved a lot of success. PaaS (Platform as a Service) service providers such as Heroku and Modulus) provides support for node deployment with a single command. Reduce page load times by up to 50% and reduce the number of servers required to host the application.

10. Thriving open source community

Node.js also has a very good community. Because of its open source community, Node.js offers many great modules that power the web The application adds more excellent functions. For example, Socket.io Can be used to handle constant communication between the client and server, 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. Furthermore, it has become a real-time Web APP A giant in the development world. All the advantages mentioned above about Node.js is that many companies consider Node.js to be the best solution for running heavy load web A good technique to apply and allow the team to use it in a production environment.
