TypeError: Cannot define property Symbol(graceful-fs.queue), object is not extensible

[niieani]

When used in an ESM context, node:fs module is not extensible.
graceful-fs tries to define a Symbol property on the fs namespace here:

node-graceful-fs/graceful-fs.js

Lines 24 to 30 in 2343799

	function publishQueue(context, queue) {
	Object.defineProperty(context, gracefulQueue, {
	get: function() {
	return queue
	}
	})
	}

This causes a TypeError:

Object.defineProperty(context, gracefulQueue, {
         ^

TypeError: Cannot define property Symbol(graceful-fs.queue), object is not extensible

Would be best if the check were to be implemented differently, rather than defining a property on node's fs module.

Maybe use WeakMap (and drop support for very old version of Node)?

Now ESM is even more prevalent, we stumbled on this issue while trying to migrate to an ESM-only build for Node.js v24 😕

Why does the docs say v4 doesn't patch node globals, when it clearly tries to? Anyway..

bun patch graceful-fs

Edit node_modules/graceful-fs/graceful-fs.js

const fs = require('fs')
module.exports = fs

bun patch --commit 'node_modules/graceful-fs'

Can't care less..
