jsx-first-prop-new-line

Enforce proper position of the first property in JSX.

Rule Details

This rule checks whether the first property of all JSX elements is correctly placed. There are the possible configurations:

• always: The first property should always be placed on a new line.
• never : The first property should never be placed on a new line, e.g. should always be on the same line as the Component opening tag.
• multiline: The first property should always be placed on a new line when the JSX tag takes up multiple lines.
• multiprop: The first property should never be placed on a new line unless there are multiple properties.
• multiline-multiprop: The first property should always be placed on a new line if the JSX tag takes up multiple lines and there are multiple properties. This is the default value.
