npm i contentful-html-to-richtext -s
This package exposes one simple method called generateRichText:
const parser = require("contentful-html-to-richtext");
let rt = parser.generateRichText(
`<a href='mailto:test'>We link!</a>
<p>This a test is <a href='mailto:test'>in text</a> test <b>Can we do it nested?</b> </p> <h1>BIG GUY</h1> but can we do more?`
);
console.log(JSON.stringify(rt, null, 2));
This should produce (if published to Contentful with contentful-management):
