Provide a defineConfig function for .eslintrc.js, and a defineFlatConfig function for eslint.config.js files.

This project is written by a human and only partially automatically generated!
Some rules are even enhanced by hand!
Unfortunately, this has the disadvantage that not everything is immediately defined. For example, if a rule is not defined, it falls back to a basic definition.
However, the advantage is that you get documentation for pretty much everything in the code and usually get a direct link to the respective plugin or eslint rule. The types are also strictly typed.

So if you are missing something like a rule or a plugin that should also be supported or a rule definition is e.g. out of date, feel free to open an issue or PR for it.

# add eslint and eslint-define-config to project’s dev dependencies
npm add --save-dev eslint eslint-define-config
# or
yarn add --dev eslint eslint-define-config
# or
pnpm add --save-dev eslint eslint-define-config

.eslintrc.js

// @ts-check
const { defineConfig } = require('eslint-define-config');

module.exports = defineConfig({
  root: true,
  rules: {
    // rules...
  },
});

eslint.config.js

// @ts-check
const { defineFlatConfig } = require('eslint-define-config');

module.exports = defineFlatConfig([
  'eslint:recommended',
  {
    plugins: {
      // plugins...
    },
    rules: {
      // rules...
    },
  },
]);

Improve your eslint configuration experience with:

• auto-suggestions
• type checking (Use // @ts-check at the first line in your .eslintrc.js or eslint.config.js)
• documentation
• deprecation warnings
