Converting CSV to JSON using NodeJS in Javascript

Web scraping is also known as a method of gathering a large amount of raw data from various websites and storing them as structured data.Selenium certification is an automation web framework for testing web applications.

Next, we have to find the data for extraction such as name, price, rating, etc.

In the following step, we need to write the code.

Furthermore, we will gather all libraries.from selenium online training import webdriverfrom BeautifulSoup import BeautifulSoupimport pandas as pdHere we will configure the web driver to use the Chrome browser.

:-content = driver.page_sourcesoup = BeautifulSoup(content)for a in soup.findAll('a',href=True, attrs={'class':'_31qSD5'}):name=a.find('div', attrs={'class':'_3wU53n'})price=a.find('div', attrs={'class':'_1vC4OE _2rQ-NK'})rating=a.find('div', attrs={'class':'hGSR34 _2beYZw'})products.append(name.text)prices.append(price.text)ratings.append(rating.text)Later we have to run the code written earlier and extract the data from the website.

Next, we have to run the whole code to get the exact results.

With constant evolutions, the Node.js technology has become a silver bullet for the developers and businesses as it filled the need by leveraging single-threaded event loop model to support concurrent requests, stimulated code sharing, enable module reuse with inbuilt NPM, served as a proxy server, enabled real-time two-way communication, and pretty more.

A quick glance at the leading players that have banked on the Node.js technology to engineer the world-class application:

Netflix stands first in switching the architecture to Node.js as it brought superior performance to the company that has significantly diminished architecture cost and development cost.

Besides, the continuous updates for security patches, and performance optimizations, and support for the JavaScript features make the apps built using Node.js platform perform speedily and efficiently.

With increasing workloads, the Node.js applications can be scaled successfully by implementing three strategies- cloning, decomposing, and splitting.

The Node.js community is getting bigger day by day with a large number of code packages and modules that can be used by the developers without building them from scratch and avoiding the layers of complexities.

NodeJS is an open source, server-side script.

JavaScript has many engines and spider monkey is the first JavaScript engine.

It was developed by Netscape.

After some years chrome has developed a V8 engine which runs on the top of Google’s open-source scripting engine V8.

It's very fast, lightweight and efficient.NodeJS uses the asynchronous mode of operation, event-driven Input/output rather than using the threads for each process and it is a cross-platform JavaScript run-time environment that executes JavaScript code to run on the server.Why Node JS?Node.js uses JavaScript for creating server side applications or we can also use any other languages that can be compiled to JavaScript (like typescript).

The JavaScript is written in the same way as we are using in any client-side application.

As a client-side JavaScript framework, AngularJSAngular enables developers to build dynamic web applications based on Model-View-Controller (MVC) architectural patterns and using HTML as the dynamic language.

AngularJS was developed by Google as a web application development framework.

It even follows JavaScript syntax rules.

Unlike NodeJS, AngularJS is a web framework.

They can embed AngularJS files in a codebase like other JavaScript files.

Both NodeJS and AngularJS support MVC architectural patterns.

Choosing the right javascript framework for your next project is the foremost decision of every developer. So here in this guide we have compare all three most popular javascript frameworks- AngularJS vs NodeJS vs ReactJS to help you to choose the right framework for your next project. Have a look.
