Frontity

Frontity is a free and open source framework to develop WordPress themes based on React JS. This is the first React framework focused on WordPress, which means that each part of it has been simplified and optimized to be used with this CMS (as headless WordPress). How does it work? Frontity apps live in a Node.js server tailored for WordPress. They use the REST API to retrieve content and generate the final HTML. Frontity is prepared to be hosted in a regular Node server or in serverless services, which makes it super cheap and infinitely scalable. Learn more at https://github.com/frontity/frontity.
