ESLint plugin for teams that want consistent TypeScript-first conventions based on:

- [`type-fest`](https://github.com/sindresorhus/type-fest)
- [`ts-extras`](https://github.com/sindresorhus/ts-extras)

The plugin ships focused rule sets for modern flat config usage, with parser setup
included in each preset config.

## Installation

```sh
npm install --save-dev eslint-plugin-typefest typescript
```

> `@typescript-eslint/parser` is loaded automatically by plugin presets.

### Compatibility

- **Supported ESLint versions:** `9.x` and `10.x`
- **Config system:** Flat Config only (`eslint.config.*`)
- **Node.js runtime:** `>=22.0.0`

## Quick start (flat config)

```js
import typefest from "eslint-plugin-typefest";

export default [typefest.configs.recommended];
```

That is enough for TypeScript files (`**/*.{ts,tsx,mts,cts}`).

## Presets

This plugin intentionally exports eight presets:

## Configuration examples by preset

```js
import typefest from "eslint-plugin-typefest";

export default [
 // Smallest baseline footprint.
 typefest.configs.minimal,

 // Balanced default for most teams.
 // typefest.configs.recommended,

 // Recommended plus type-aware ts-extras helper rules.
 // typefest.configs["recommended-type-checked"],

 // Recommended plus additional stable runtime utilities.
 // typefest.configs.strict,

 // Every stable rule.
 // typefest.configs.all,

 // Every stable rule plus experimental candidate rules.
 // typefest.configs.experimental,

 // Focused subsets:
 // typefest.configs["type-fest/types"],
 // typefest.configs["ts-extras/type-guards"],
];
```

### Parser setup behavior

Each preset already includes:

- `files: ["**/*.{ts,tsx,mts,cts}"]`
- `languageOptions.parser` (`@typescript-eslint/parser`)
- `languageOptions.parserOptions`:
  - `ecmaVersion: "latest"`
  - `projectService: true` (for presets that include typed rules, such as `recommended-type-checked`, `strict`, `all`, and `experimental`)
  - `sourceType: "module"`

End users usually do **not** need to wire parser config manually.

If you need custom parser options (for example `tsconfigRootDir`), extend a preset:

```js
import typefest from "eslint-plugin-typefest";

const recommended = typefest.configs.recommended;

export default [
 {
  ...recommended,
  languageOptions: {
   ...recommended.languageOptions,
   parserOptions: {
    ...recommended.languageOptions?.parserOptions,
    // Add projectService only when you opt into a type-aware preset.
   },
  },
 },
];
```

## Global settings

You can globally disable autofixes that add missing imports while still keeping
rule reports and non-import autofixes enabled.

```js
import typefest from "eslint-plugin-typefest";

export default [
 {
  ...typefest.configs.recommended,
  settings: {
   typefest: {
    // Disable all autofixes while keeping suggestions enabled.
    // disableAllAutofixes: true,

    // Disable only autofixes that add missing imports.
    disableImportInsertionFixes: true,
   },
  },
 },
];
```

When `settings.typefest.disableImportInsertionFixes` is `true`, rules that
would normally add a missing `type-fest` or `ts-extras` import will report
without applying that import-adding autofix. Autofixes that do not require
inserting a new import (for example, when the replacement symbol is already in
scope) still apply.

When `settings.typefest.disableAllAutofixes` is `true`, all rule autofixes are
suppressed, but reports and suggestions remain available.

If both settings are enabled, `disableAllAutofixes` takes precedence for
autofix behavior.

## Rules

- `Fix` legend:
  - `🔧` = autofixable
  - `💡` = suggestions available
  - `—` = report only
- `Preset key` legend:
