# vue/no-irregular-whitespace

> disallow irregular whitespace in `.vue` files

## :book: Rule Details

`vue/no-irregular-whitespace` rule is aimed at catching invalid whitespace that is not a normal tab and space. Some of these characters may cause issues in modern browsers and others will be a debugging issue to spot.
`vue/no-irregular-whitespace` rule is the similar rule as core [no-irregular-whitespace] rule but it applies to the source code in .vue.

<eslint-code-block :rules="{'vue/no-irregular-whitespace': ['error']}">

```vue
<template>
  <!-- ✓ GOOD -->
  <div class="foo bar" />
  <!-- ✗ BAD -->
  <div class="foobar" />
  <!--           ^ LINE TABULATION (U+000B) -->
</template>
<script>
/* ✓ GOOD */
var foo = bar;
/* ✗ BAD */
var foo =bar;
//       ^ LINE TABULATION (U+000B)
</script>
```

</eslint-code-block>
