Why Use DFK JS Rendering Service.

Base Fetcher

"Base Fetcher" is suitable for processing server-side rendered pages where the HTML in the HTTP response contains all content.

Crawling a URL with "Base fetcher" takes less resources and works faster than rendering HTML with "Chrome fetcher".

Requesting static HTML pages is always cheaper ...

But...

Chrome Fetcher

The most of modern web applications are built using JavaScript Frameworks like Angular, React, Vue.js. They consist of HTML + JS code. HTML initially does not contain all the actual content. It loads dynamically after rendering JavaScript code.

So scraping such pages 'as is' is useless for the most cases.

Headless Chrome browser is used by "Chrome fetcher" for rendering dynamic content and returning it as a static HTML. This renders websites in the exact same way as real browser would do it.

V/S

Automation of manual workflows.

Of course, we don’t intend to only render JavaScript driven web pages, but to perform tasks with them.

Doing actions helps you to be closer to desired data.

Actions are performed by scraper upon visiting a Web page, and it simulates real-world human interaction with the page.

Specifically, you can use DFK API for executing simple actions after rendering a web page:

Input action

Specify Input CSS Selector and Input Text to perform search queries, or fill forms.

Click action

Click on an element with specified CSS Selector.

Wait action

Wait for the specific DOM elements you want to manipulate next.

Scroll action

Automatically scroll a page down to load more content, simulating user interaction with infinite scrolled pages.

Let machines do the grunt work and let humans do what they do best.

Proxy and Geo-Targetting.

Dataflow kit Proxies pool is used to get around content download restrictions from certain websites.

Choose the one from 100+ supported global locations to send your web scraping API requests.

Or select "country-any" to simply use random geo-targets.
