What does your .oxlintrc.json config file look like?

{
  "$schema": "./node_modules/oxlint/configuration_schema.json",
  "plugins": [
    "eslint",
    "import",
    "typescript",
    "unicorn",
    "react",

  },
}

import { definePlugin, defineRule } from 'oxlint';

// oxlint-disable-next-line no-default-export
export default definePlugin({
  meta: { name: 'my-custom-plugin' },
  rules: {
    'no-switch': defineRule({
      create: context => ({
        SwitchStatement: node =>
          context.report({node: node, message: 'Do not use switch 🙏'}),
      }),
    }),
  },
});

What happened?

WARNING: JS plugins are experimental and not subject to semver.

Failed to parse configuration file.

I also tried to use absolute (just or testing not committable) with /Users/MyUser/Project/my-custom-plugin.js

  × Failed to load JS plugin: /Users/my-custom-plugin.js
  │   TypeError [ERR_INVALID_MODULE_SPECIFIER]: Invalid module "\Users\MyUser\Project\my-custom-plugin.js" is not a valid package name imported from C:\Users\MyUser\Project\node_modules\.pnpm\oxlint@1.19.0\node_modules\oxlint\dist\plugins.js

  │     at packageResolve (node:internal/modules/esm/resolve:768:81

Then I tried absolute pointing on a directory having a package.json with a main the plugin but gave the same error. Changing main in package.json made it not finding the js file. Also tried .cjs with no success either.

Is this an accurate repro of ths issue? https://github.com/camc314/oxlint-repros/tree/main/issue-14375

[overlookmotel]

Maybe we should run NAPI tests on Windows on CI? Presumably that'd have revealed this bug.

[camc314]

yeah your right. i assumed we ran them (but only on main branch), but it looks like we dont

[overlookmotel]

Thanks very much for catching this @Hideman42!

[Hideman42]

Hi, I tried again today with oxlint 1.23.0, it looks to load the plugin or at least I dont have the same error.
Now getting memory allocation issue as follows memory allocation of 4294967280 bytes failed

[overlookmotel]

Sorry this is proving so rubbish for you! 2 questions:

1. How much RAM does your machine have?
2. What version of Windows?
3. Can you please give the complete output? If there's any stack trace, that'd be really helpful.

Also, the 3 people who 👍 Hideman's comment: Does 👍 mean you have hit the same problem? If so, if you could also give the above details, that'd be a big help. This smells like the kind of thing that's going to be a battle to isolate and fix - so the more info we can gather, the better.

I just encountered this issue on my Windows machine running pnpm oxlint with sapphi-red/vite@46e59c8.

To answer for my case:

1. 32GB
2. Windows 11 Pro 24H2 26100.6899
3. The output does not have any additional information other than the memory allocation error.

   $ pnpm oxlint scripts
   WARNING: JS plugins are experimental and not subject to semver.
   Breaking changes are possible while JS plugins support is under development.
   memory allocation of 4294967280 bytes failed
   

It worked fine on WSL so it's a Windows specific problem.

I've taken a deeper look. It seems this while loop is running infinitely.
