ignore	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.

JavaScript

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

For example:

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:

matrix(1, 0, 0, 0, 1, 0, 0, 0, 1);

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

JSX

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

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

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

}

Markdown

Do   not    format   this
