[Chrome Extension] console debug mode will crash crash your app when using localStorage.setItem("debug", "nuqs")

[dejoma]

Context

    "nuqs": "^2.2.3",

What framework are you using?

• ✅ Next.js (app router)

Which version of your framework are you using?

14.2.20

Description & reproduction

On localhost; go to console and do:

localStorage.setItem("debug", "nuqs")

Then go to any page with parameters that have default value. For me it was a boolean parsen "open" with default false. Then if you go to any page it will give "cannot parse null to string";

I see the error comes from a Chrome Extension, any idea which one it might be?

[dejoma]

The thing that makes it clash/crash/not-work is localStorage.setItem("debug", "nuqs")

If I undo that; it immediately works again. Chrome extension probably is react-dev-tools

[franky47]

I can confirm that fmkadmapgofadopljbjfkapdkoienihi is react-developer-tools, but even with a fresh Chrome install and this extension, I cannot reproduce the error.

If you go into node_modules/nuqs/dist/chunk-3RCMAOX7.js and remove the following lines, does it work? (remember to delete your .next folder to avoid using a cached bundled dependency):

function debug(message, ...args) {
  if (!enabled) {
    return;
  }
-  const msg = sprintf(message, ...args);
-  performance.mark(msg);
  console.log(message, ...args);
}
