# Prettier

> Explore Prettier, the powerful code formatter. Learn how to install, configure, and effectively use Prettier to enhance your coding workflow.

[**Prettier**](https://prettier.io/) is a formatter for CSS, SCSS, JavaScript, JSON, Markdown, TypeScript, GraphQL and YAML.

You can enable the Prettier formatter with:

```shell theme={null}
trunk check enable prettier
```

## Auto Enabling

Prettier will be auto-enabled if any *TypeScript, YAML, CSS, PostCSS, Sass, HTML, Markdown, JSON, JavaScript, GraphQL or Prettier\_supported\_configs* files are present.

## Settings

Prettier supports the following config files:

* `.prettierrc`
* `.prettierrc.json`
* `.prettierrc.yml`
* `.prettierrc.yaml`
* `.prettierrc.json5`
* `.prettierrc.js`
* `.prettierrc.cjs`
* `.prettierrc.mjs`
* `prettier.config.js`
* `prettier.config.cjs`
* `prettier.config.mjs`
* `.prettierrc.toml`
* `.prettierignore`

You can move these files to `.trunk/configs` and `trunk check` will still find them. See [Moving Linters](../configure-linters#moving-linters) for more info.

## Usage Notes

By default, Trunk uses Prettier to autoformat many languages/config formats, including markdown. To line wrap within markdown, you need to set the following in your [Prettier config](https://prettier.io/docs/en/configuration.html) `.prettierrc.yaml`, etc.

```yaml theme={null}
proseWrap: always
```

You may also want to configure `printWidth` to your liking.
