I am building Chrome extension which at some point should determine current page language. In order to do that, my plan is to extract text content of the page (or at least a part of it) and pass it to translation api. However I couldn't find any strait forward way to just get all textNodes of the document.
There is a backup plan which is to recursively analyze $('body').contents() until there is enough text content, but it feels a bit flaky. Perhaps there is a better way?
Note: Chrome extensions api allows your script to access user page dom as if it was the part of it.

Use the textContent property to get the text of an html element, e.g. const text = box. textContent . The textContent property returns the text content of the element and its descendants. If the element is empty, an empty string is returned.
textContents is all text contained by an element and all its children that are for formatting purposes only. innerText returns all text contained by an element and all its child elements.
HTML specifies that a <script> tag inserted with innerHTML should not execute. For that reason, it is recommended that instead of innerHTML you use: Element.SetHTML() to sanitize the text before it is inserted into the DOM.
Javascript:
document.body.textContent
