Is it possible to use with the new/flat config file format?

[OJFord]

If I add it to plugins like:

import svelte from "eslint-plugin-svelte"

export default = [
  "eslint:recommended",

  {
    plugins: {
      svelte,
    },

    rules: {
      "comma-dangle": [
        "error",
        "always-multiline",
      ],
      // ...
  },
]

then there's no error, but it doesn't seem to apply rules to Svelte files.

If I add svelte.configs.recommended to the array then it errors on unexpected keyword 'extends'.

I have it working with just the parser, no svelte/* rules, as:

import svelteParser from "svelte-eslint-parser";

export default [
  "eslint:recommended",

  {
    languageOptions: {
      globals: {
        document: true,
        process: true,
      },
    },

  {
    rules: {
      // ...
    },
  },

  {
    files: [
      "**/*.svelte",
    ],

    languageOptions: {
      parser: svelteParser,
    },
  },
];

with the rules in a separate section it seems to work to apply these globally, and then the next section on only svelte files just overrides the parser. I can't find this clearly documented, but it seems to work well.

I'd still appreciate any pointers for how I can get the Svelte-specific rules from this plugin working though.

cf. also #340 (comment)

Got it, add:

import svelte from "eslint-plugin-svelte"

svelte to plugins, and ...svelte.configs.recommended.rules to rules in the config with svelteParser.
