There is a browser evaluator that you can use to evaluate Surgeon in a browser.

Surgeon itself does not deal with evaluation of scripts. Surgeon only works with the given DOM tree.

So, How do I run the browser evaluator on Puppeteer?
Sorry, for me, the documentation wasn't clear enough.

The linked example gives all the code to initialize Surgeon in a browser environment.

import {
  browserEvaluator
} from './evaluators';

surgeon({
  evaluator: browserEvaluator()
});

Sorry, I'm facing the same challenge and have no idea how to use this code snippet to interact with Puppeteer. To make it concrete, with pure Puppeteer I would write something like this:

const titles = await page.evaluate(() =>
    Array.from(document.querySelectorAll('h1.title')))
      .map(titles => titles.innerText.trim())
    )

How do I put this together with your code snippet above?
