jsx-indent

Enforce JSX indentation.

Note: The fixer will fix whitespace and tabs indentation.

Rule Details

This rule is aimed to enforce consistent indentation style. The default style is 4 spaces.

Examples of incorrect code for this rule:

// 2 spaces indentation
<App>
  <Hello />
</App>

// no indentation
<App>
<Hello />
</App>

// 1 tab indentation
<App>
  <Hello />
</App>

Rule Options

It takes an option as the second parameter which can be "tab" for tab-based indentation or a positive number for space indentations. To enable checking the indentation of attributes or add indentation to logical expressions, use the third parameter to turn on the checkAttributes (default is false) and indentLogicalExpressions (default is false) respectively.
