# Rules & Presets

Presets provide ready-to-use groups of rules. Add them directly to the flat config array, then use a later [`rules`](https://rslint.rs/config/rules.md) entry for project-specific overrides.

Import presets from `@rslint/core`:


```ts
import {
  defineConfig,
  js,
  ts,
  reactPlugin,
  reactHooksPlugin,
  importPlugin,
  nodePlugin,
  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:

| Baseline                 | What it covers                                                                        |
| ------------------------ | ------------------------------------------------------------------------------------- |
| `recommended`            | Rules that catch code likely to be buggy, using syntax alone                          |
| `recommendedTypeChecked` | `recommended` plus the rules that read type information                               |
| `strict`                 | `recommended` plus opinionated rules that catch more bugs at the cost of more reports |
| `strictTypeChecked`      | `strict` plus the rules that read type information                                    |

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

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

Every `ts.configs.*` preset declares the `@typescript-eslint` plugin. Like upstream, presets do not set project discovery options. Enable `parserOptions.projectService: true` explicitly for automatic discovery, or use `parserOptions.project` to select TypeScript projects. Type-aware rules run only for files with a selected project; [gap files](https://rslint.rs/guide/type-checking.md#gap-files) retain source-only linting.

To configure a rule manually, see [`rules`](https://rslint.rs/config/rules.md). To enable rules outside a preset, see [`plugins`](https://rslint.rs/config/plugins.md). The complete [Rules](https://rslint.rs/rules/index.md) reference documents rule-specific options.
