heading-has-content

Enforce that heading elements (h1, h2, etc.) have content and that the content is accessible to screen readers. Accessible means that it is not hidden using the aria-hidden prop. Refer to the references to learn about why this is important.

Rule details

This rule takes one optional object argument of type object:

{
    "rules": {
        "jsx-a11y/heading-has-content": [ 2, {
            "components": [ "MyHeading" ],
          }],
    }
}

For the components option, these strings determine which JSX elements (always including <h1> thru <h6>) should be checked for having content. This is a good use case when you have a wrapper component that simply renders an h1 element (like in React):

// Header.js
const Header = props => {
  return (
    <h1 {...props}>{ props.children }</h1>
  );
}

...

// CreateAccount.js (for example)
...
return (
  <Header>Create Account</Header>
);

Bad

function Foo(props) {
  return <label {...props} />
}

Succeed

<h1>Heading Content!</h1>
<h1><TextWrapper /><h1>
<h1 dangerouslySetInnerHTML={{ __html: 'foo' }} />

Fail

<h1 />
<h1><TextWrapper aria-hidden />
