R packages - May 2022 - [R] shadowr: Selenium plugin to manage multiple levels of shadow elements on web page

Dear R users,


I am happy to announce that my new package shadowr is now available on
CRAN.

The package enables to use the shadow selenium
plugin<https://github.com/sukgu/shadow-automation-selenium> to manage
multi level shadow DOM elements on web page.

Shadow DOM is a web standard that offers component style and markup
encapsulation.

It is a critically important piece of the Web Components story as it ensures
that a component will work in

any environment even if other CSS or JavaScript is at play on the page.

The problem is that Custom HTML tags can?t be directly identified with selenium
tools.

If you just need to click a cookie accept button and if there is only a one
level shadow dom structure,

you could just copy the js path and let the selenium driver execute this js
code.

For details and examples please check out the github page.

But when you have a multi level shadow dom structure and have to do different
things with the elements like get the text or click them,

sooner or later things get complicated.

You would have to handle a lot of long strings and depending on the action and
amount of elements also modify/extend the strings.

Shadowr enable R users a more comfortable and reliable way to work with shadow
dom elements.
