    Rules & Presets

    Presets provide ready-to-use groups of rules. Add them directly to the flat config array, then use a later rules entry for project-specific overrides.

    Import presets from @rslint/core:

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

    Choosing a TypeScript preset

    The ts.configs.* presets mirror typescript-eslint's own layering. Pick one baseline:

    BaselineWhat it covers
    recommendedRules that catch code likely to be buggy, using syntax alone
    recommendedTypeCheckedrecommended plus the rules that read type information
    strictrecommended plus opinionated rules that catch more bugs at the cost of more reports
    strictTypeCheckedstrict plus the rules that read type information

    stylistic and stylisticTypeChecked hold the consistency rules. Layer one after the baseline:

    export default defineConfig([
  js.configs.recommended,
  ts.configs.strictTypeChecked,
  ts.configs.stylisticTypeChecked,
]);

    Every ts.configs.* preset declares the @typescript-eslint plugin and enables parserOptions.projectService, so the type-checked variants run as-is.

    To configure a rule manually, see rules. To enable rules outside a preset, see plugins. The complete Rules reference documents rule-specific options.
