Additional context

ESLint V9 support is adressed in https://github.com/TanStack/query/pull/7543

I did some inital work to export a flat/recommended config earlier which seemed to work, but a bit more testing was still needed. See https://github.com/TanStack/query/compare/main...davidjbng:query:eslint-v9-flat-config

Workaround, if people need it:

import { fixupPluginRules } from '@eslint/compat';
import * as eslintPluginTanstackQuery from '@tanstack/eslint-plugin-query';

export default [
  {
    plugins: {
      '@tanstack/query': fixupPluginRules(eslintPluginTanstackQuery),
    },
    rules: eslintPluginTanstackQuery.configs.recommended.rules,
  },
];
