jsx-a11y/heading-has-content

People who use a screen reader move through a page by its headings. An empty h1 to h6, or one with only hidden content, is a stop in that list with nothing to read.

Text, an expression and a visible element count as content. So do the children and dangerouslySetInnerHTML props. A heading that's hidden itself with aria-hidden isn't checked.

Configure#

Off by default. To turn it on:

[lint.rules]
"jsx-a11y/heading-has-content" = "error" # or "warn"

Every option, set to its default:

[lint.rules]
"jsx-a11y/heading-has-content" = ["error", {
  components = [], # list of strings
}]

Examples#

const title = <h1 className="hero" />;
const section = <h2><span aria-hidden>Pricing</span></h2>;

const title = <h1 className="hero">{page.title}</h1>;
const section = <h2><span>Pricing</span></h2>;

Options#

const title = <Heading level={1} />;
