It is an unavoidable fact that web scraping gives life to many applications today. It is frequently used especially in the field of artificial intelligence. A large amount of data is needed to test the developed algorithms and to reduce the error rates.

The most popular and fastest way to obtain data from the Internet is to use web scraping tools. Web scraping tools work in an automated manner, regularly collecting and streaming data from target websites.

Web scraping tools basically use web scraping APIs. The number of web scraping APIs is increasing. Zenscrape provides the most popular web scraping API available today. With the flexible and free packages it provides, it serves more than 10,000 developers and businesses.

One of the reasons why the web scraping API provided by Zenscrape is frequently preferred today is that it works very fast. With the free and large proxy pool it provides, it ensures that the processes are automated and fast without any blocking.

Thanks to the powerful infrastructure and flexible structure of Zenscape web scraping API, it can be easily integrated into many programming languages. In this article, we will look at how to easily integrate Zenscape API into javascript programming language. So let’s get started.

Integration Zenscrape API to javascript

Get an API key

Before we integrate the web scraping API that Zenscrape provides, we need to obtain an API key. Here we sign up by choosing the flexible packages or the free package that Zenscrape offers. Then we will get the API key.

Create a javascript file

After getting the API key, everything is ready to integrate the Zenscrape API into the code side. We are creating a javascript file because we will integrate the Zenscrape API into the javascript programming language.

Check fetch() library

After creating a javascript file we need a library that allows us to make requests to the Zenscrape API. For this, we will use the ‘fetch’ library, which is one of the most popular libraries. More detailed information can be found here

Paste the code

Let’s paste the following codes into the javascript file we created. 

 

var requestOptions = {
  method: ‘GET’,
  redirect: ‘follow’
};

fetch(“https://app.zenscrape.com/api/v1/get?apikey=d58871c0-3da6-11ed-99ac-a9588c8b45db&url=https://www.arubanetworks.com/techdocs/ClearPass/CPGuest_UG_HTML_6.5/Content/Reference/BasicHTMLSyntax.htm”, requestOptions)
  .then(response => response.text())
  .then(result => console.log(result))
  .catch(error => console.log(‘error’, error));

 

This snippet will request the Zenscape API with fetch. The target url to scrape is https://www.arubanetworks.com/techdocs/ClearPass/CPGuest_UG_HTML_6.5/Content/Reference/BasicHTMLSyntax.htm .Before running the code, you can take a look at the source code of this page.

Run

Everything is ready. Let’s run the code in the javascript file we created. After this code runs, the following information will be printed on the console of the application.
