**Knip configuration for @kitschpatrol/shared-config.**

<!-- /description -->

## Overview

It's a shared [Knip](https://knip.dev) config, plus a command-line tool `kpi-knip` to perform Knip-related project initialization, linting, and fixing.

<!-- recommendation -->

> [!IMPORTANT]
>
> **You can use this package on its own, but it's recommended to use [`@kitschpatrol/shared-config`](https://www.npmjs.com/package/@kitschpatrol/shared-config) instead for a single-dependency and single-package approach to linting and fixing your project.**
>
> This package is included as a dependency in [`@kitschpatrol/shared-config`](https://www.npmjs.com/package/@kitschpatrol/shared-config), which also automatically invokes the command line functionality in this package via its `kpi` command

<!-- /recommendation -->

## Setup

To use just this Knip config in isolation:

1. Install the `.npmrc` in your project root. This is required for correct PNPM behavior:

   ```sh
   pnpm dlx @kitschpatrol/repo-config init
   ```

2. Add the package:

   ```sh
   pnpm add -D @kitschpatrol/knip-config
   ```

3. Add the starter `knip.config.ts` files to your project root, and add any customizations you'd like:

   ```sh
   pnpm exec kpi-knip init
   ```

## Usage

Integrate with your `package.json` scripts as you see fit, for example:

```json
{
  "scripts": {
    "lint": "kpi-knip lint"
  }
}
```

### Configuration

To create a `knip.config.ts` in your project root:

```sh
pnpm exec kpi-knip init
```

(Note that this will delete the `knip` property in your `package.json`!)

_Or_

To create a `knip` property in `package.json`:

```sh
pnpm exec kpi-knip init --location package
```

(Note that this will delete the `knip.config.ts` file in your project root!)
