Support eslint flat config

[peachest]

Currently this project is not support eslint's new flat config feature. Is there any plan?

[KristjanTammekivi]

As a temporary solution the following seems to work:

import youDontNeedLodashUnderscorePlugin from 'eslint-plugin-you-dont-need-lodash-underscore';
import { fixupPluginRules } from '@eslint/compat';
        ...
        plugins: {
            'you-dont-need-lodash-underscore': fixupPluginRules(youDontNeedLodashUnderscorePlugin)
        },
        ...

@KristjanTammekivi does this work for you?

During testing months ago yes, but I haven't merged it yet because one specific rule in eslint-plugin-import still doesn't work

What I'm about to say seems obvious now that I have my config properly set up, but when I first came across this issue, I misunderstood that the recommended config only registers the plugin but doesn't enable any rules.

To take the provided example one step further, here's a snippet from my config referencing the rules configs (in my case all-warn):

import { fixupPluginRules } from "@eslint/compat";
import youDontNeedLodashUnderscorePlugin from "eslint-plugin-you-dont-need-lodash-underscore";

export default [
  // ...
  {
    plugins: {
      "you-dont-need-lodash-underscore": fixupPluginRules(
        youDontNeedLodashUnderscorePlugin,
      ),
    },
    rules: {
      ...youDontNeedLodashUnderscorePlugin.configs["all-warn"].rules,
    },
  },
  // ...
];

Alternative to all-warn, there is also all, compatible, and compatible-warn, as can be seen in index.js
