Validate closing bracket location in JSX (react/jsx-closing-bracket-location)

Enforce the closing bracket location for JSX multiline elements.

Fixable: This rule is automatically fixable using the --fix flag on the command line.

Rule Details

This rule checks all JSX multiline elements and verifies the location of the closing bracket. By default this one must be aligned with the opening tag.

The following patterns are considered warnings:

<Hello
  lastName="Smith"
  firstName="John" />;

<Hello
  lastName="Smith"
  firstName="John"
  />;

The following patterns are not considered warnings:

<Hello firstName="John" lastName="Smith" />;

<Hello
  firstName="John"
  lastName="Smith"
/>;

Rule Options

There are two ways to configure this rule.

The first form is a string shortcut corresponding to the location values specified below. If omitted, it defaults to "tag-aligned".

"react/jsx-closing-bracket-location": <enabled> // -> [<enabled>, "tag-aligned"]
"react/jsx-closing-bracket-location": [<enabled>, "<location>"]

The second form allows you to distinguish between non-empty and self-closing tags. Both properties are optional, and both default to "tag-aligned". You can also disable the rule for one particular type of tag by setting the value to false.

"react/jsx-closing-bracket-location": [<enabled>, {
  "nonEmpty": "<location>" || false,
  "selfClosing": "<location>" || false
}]

location

Enforced location for the closing bracket.

• tag-aligned: must be aligned with the opening tag.
• line-aligned: must be aligned with the line containing the opening tag.
• after-props: must be placed right after the last prop.
• props-aligned: must be aligned with the last prop.

Defaults to tag-aligned.

For backward compatibility, you may pass an object { "location": <location> } that is equivalent to the first string shortcut form.
