## Usage

### Install

Install `jest`, `prettier` and `jest-runner-prettier`

```bash

yarn add --dev jest prettier jest-runner-prettier

# or with NPM

npm install --save-dev jest prettier jest-runner-prettier

```

### Add it to your Jest config

#### Using Built-in Preset

This package includes a [Jest preset](https://jestjs.io/docs/en/configuration#preset-string) which configures Jest to run Prettier on all files supported by Prettier. To use it set the following in your `package.json`:

```json

{

  "jest": {

    "preset": "jest-runner-prettier"

  }

}

```

or `jest.config.js`:

```js

module.exports = {

  preset: "jest-runner-prettier",

};

```

#### Manually

In your `package.json`

```json

{

  "jest": {

    "runner": "prettier",

    "moduleFileExtensions": [

      "js",

      "mjs",

      "jsx",

      "vue",

      "ts",

      "tsx",

      "css",

      "less",

      "scss",

      "html",

      "json",

      "graphql",

      "md",

      "markdown",

      "mdx",

      "yaml",

      "yml"

    ],

    "testMatch": [

      "**/*.js",

      "**/*.mjs",

      "**/*.jsx",

      "**/*.vue",

      "**/*.ts",

      "**/*.tsx",

      "**/*.css",

      "**/*.less",

      "**/*.scss",

      "**/*.html",

      "**/*.json",

      "**/*.graphql",

      "**/*.md",

      "**/*.markdown",

      "**/*.mdx",

      "**/*.yaml",

      "**/*.yml"

    ]

  }

}

```

Or in `jest.config.js`

```js
