To access the DOM from a Webpack loader, you can use the jsdom package.


Here is an example of how you can access the DOM from a Webpack loader:

  1. Install the jsdom package:
1
npm install jsdom


  1. Import the jsdom package in your Webpack loader file:
1
const { JSDOM } = require('jsdom');


  1. Access the DOM in your loader's pitch or loader function:
 1

11

15
module.exports = function(source) {
  // Create a new JSDOM instance
  const dom = new JSDOM(source);

  // Access the window object and the document
  const { window } = dom;
  const { document } = window;

  // Manipulate the DOM as needed
  const title = document.querySelector('h1');
  console.log(title.textContent);

  // Return the modified source code
  return source;
};


In this example, the source argument represents the source code that was passed to the loader. It is usually a string.
