Put this into a patches folder and add this configuration to your package.json:

"pnpm": {
    "patchedDependencies": {
      "jsdom": "patches/jsdom.patch"
    }
  }

Using patch-package to apply this. 👍

for jsdom 26.1.0 it shifted one line (i guess it will happen in between versions a lot)

@maapteh Thanks, I updated the gist.

Maybe its handy to keep every version isolated, not many people need to stay latest. Thank you for your work! Hopefully something better will arrive with Jest :)

FYI this no longer seems to work on jsdom 27.4.0 (of course line numbers have changed, but I mean the patch in general doesn't work anymore). Despite setting configurable to true, I get Error: Not implemented: navigation (except hash changes).

Edit: Never mind. My issue was that I had a direct dependency against jsdom. I removed it from my own package and just use jest-environment-jsdom which internally depends on jsdom.

Then you need to create this patch file patches/jest-environment-jsdom++jsdom+26.1.0.patch

(This will patch the jsdom that is inside jest-environment-jsdom)

diff --git a/node_modules/jest-environment-jsdom/node_modules/jsdom/lib/jsdom/browser/Window.js b/node_modules/jest-environment-jsdom/node_modules/jsdom/lib/jsdom/browser/Window.js

And run npx patch-package
