Prevent void DOM elements (e.g. <img />
, <br />
) from receiving children (react/void-dom-elements-no-children)
There are some HTML elements that are only self-closing (e.g. img
, br
, hr
). These are collectively known as void DOM elements. If you try to give these children, React will give you a warning like:
Invariant Violation: img is a void element tag and must neither have
children
nor usedangerouslySetInnerHTML
.
The following patterns are considered warnings:
<br>Children</br>
<br children='Children' />
<br dangerouslySetInnerHTML={{ __html: 'HTML' }} />
React.createElement('br', undefined, 'Children')
React.createElement('br', { children: 'Children' })
React.createElement('br', { dangerouslySetInnerHTML: { __html: 'HTML' } })
The following patterns are not considered warnings:
<div>Children</div>
<div children='Children' />
<div dangerouslySetInnerHTML={{ __html: 'HTML' }} />
React.createElement('div', undefined, 'Children')
React.createElement('div', { children: 'Children' })
React.createElement('div', { dangerouslySetInnerHTML: { __html: 'HTML' } })
