     …
   ]
 }
 …

Or use it on the CLI directly

Or use this on the API:

 import {remark} from 'remark'
 import {reporter} from 'vfile-reporter'
 import remarkLint from 'remark-lint'
 import remarkLintMaximumHeadingLength from 'remark-lint-maximum-heading-length'

 remark()
   .use(remarkLint)
+  .use(remarkLintMaximumHeadingLength)
   .process('_Emphasis_ and **importance**')
   .then((file) => {
     console.error(reporter(file))
   })
