title: Ignoring Code
---

Prettier offers an escape hatch to ignore a block of code or prevent entire files from being formatted.

## Ignoring Files

To exclude files from formatting, add entries to a `.prettierignore` file in the project root or set the [`--ignore-path` CLI option](cli.md#ignore-path).

## JavaScript

A JavaScript comment of `// prettier-ignore` will exclude the next node in the abstract syntax tree from formatting.

For example:

<!-- prettier-ignore -->
```js
matrix(
  1, 0, 0,
  0, 1, 0,
  0, 0, 1
)

// prettier-ignore
matrix(
  1, 0, 0,
  0, 1, 0,
  0, 0, 1
)
```

will be transformed to:

```js
matrix(1, 0, 0, 0, 1, 0, 0, 0, 1);

// prettier-ignore
matrix(
  1, 0, 0,
  0, 1, 0,
  0, 0, 1
)
```

## JSX

```jsx
<div>
  {/* prettier-ignore */}
  <span     ugly  format=''   />
</div>
```

## HTML

```html
<!-- prettier-ignore -->
<div         class="x"       >hello world</div            >

<!-- prettier-ignore-attribute -->
<div
  (mousedown)="       onStart    (    )         "
  (mouseup)="         onEnd      (    )         "
></div>

<!-- prettier-ignore-attribute (mouseup) -->
<div
  (mousedown)="onStart()"
  (mouseup)="         onEnd      (    )         "
></div>
```

## CSS

```css
/* prettier-ignore */
.my    ugly rule
{

}
```

## Markdown

```markdown
<!-- prettier-ignore -->
Do   not    format   this
```

### Range Ignore

_available in v1.12.0+_

This type of ignore is only allowed to be used in top-level and aimed to disable formatting for auto-generated content, e.g. [`all-contributors`](https://github.com/kentcdodds/all-contributors), [`markdown-toc`](https://github.com/jonschlinkert/markdown-toc), etc.

```markdown
<!-- prettier-ignore-start -->
<!-- SOMETHING AUTO-GENERATED BY TOOLS - START -->

| MY | AWESOME | AUTO-GENERATED | TABLE |
|-|-|-|-|
| a | b | c | d |

<!-- SOMETHING AUTO-GENERATED BY TOOLS - END -->
<!-- prettier-ignore-end -->
```

## GraphQL

```graphql
{
  # prettier-ignore
  addReaction(input:{superLongInputFieldName:"MDU6SXNzdWUyMzEzOTE1NTE=",content:HOORAY}) {
    reaction {content}
  }
}
```
