next-drupal

Next.js for Drupal has everything you need to build a next-generation front-end for your Drupal site: SSG, SSR, and ISR, Multi-site, Authentication, Webforms, Search API, I18n and Preview mode (works with JSON:API and GraphQL). Maintained by chapter-three on GitHub, where it has earned 711 stars from the community.

It's actively developed around nextjs, drupal, drupal-modules, and is a solid reference for anyone building with these tools.
