    Import presets from @rslint/core:

    import {
  defineConfig,
  js,
  ts,
  reactPlugin,
  reactHooksPlugin,
  importPlugin,
  promisePlugin,
  jestPlugin,
  unicornPlugin,
  jsxA11yPlugin,
} from '@rslint/core';

    rules

    • Type: Record<string, RuleSeverity | [RuleSeverity, ...options]>

    Configure individual rules with a severity level and optional options.

    Severity levels:

    ValueDescription
    "error"Reports as error, causes non-zero exit code
    "warn"Reports as warning
    "off"Disables the rule

    String format (severity only):

    rules: {
  '@typescript-eslint/no-explicit-any': 'error',
  '@typescript-eslint/require-await': 'off',
}

    Array format (severity + options):

    rules: {
  '@typescript-eslint/array-type': ['warn', { default: 'array-simple' }],
  '@typescript-eslint/no-unused-vars': ['error', {
    argsIgnorePattern: '^_',
    varsIgnorePattern: '^_',
  }],
}

    plugins

    • Type: string[]

    Plugin names to enable. Available plugins:

    PluginRules Prefix
    @typescript-eslint@typescript-eslint/*
    reactreact/*
    react-hooksreact-hooks/*
    importimport/*
    promisepromise/*
    jestjest/*
    unicornunicorn/*
    jsx-a11yjsx-a11y/*

    ESLint core rules (e.g. no-unused-vars, prefer-const, no-var) have no prefix and do not belong to any plugin — they can be enabled directly in rules without listing anything in plugins.

    Tip

    When using JS/TS config with presets (e.g., ts.configs.recommended), plugins are declared within the preset — you don't need to specify them separately.

    For a full list of available rules and their options, see the Rules reference.
