Not compatible with eslint 9+. Invalid `languageOptions.globals` object key "AudioWorkletGlobalScope "

[k-paxian]

With latest eslint 9.17.0
They now validating the configs before applying them

this.language.validateLanguageOptions(this.languageOptions);

So it fails to apply this plugin 🤷

Also it needs to be aligned with this new way of defining globals
https://eslint.org/docs/latest/use/configure/language-options#predefined-global-variables

I have the same issue, same error.

workaround. We shouldn't need these globals anyway

import pluginVueA11y from 'eslint-plugin-vuejs-accessibility';

const a11yConfig = pluginVueA11y.configs['flat/recommended'];

a11yConfig.forEach((x) => {
  // there seems to be problem with the globals.
  // We shouldn't need these anyways because we use typescript
  // to define global variables.
  // @ts-expect-error -- deleting is intentional here.
  delete x.languageOptions.globals;
});

The actual fix for this is to update all versions of globals in your dependency tree, which you can typically do with npm update globals though you might need to "force" a higher major version to be used by explicitly adding globals as a dependency and then removing it again.

Specifically, you want to not be using v13.12.1.

An indirect issue with eslint-plugin-vuejs-accessibility that would help prevent this is that they're using globals as an implicit dependency, which is why package managers don't help you here - this can be fixed by #1280 and/or #1299
