I've written previously about my excitement that Tugboat now offers live previews for core and contrib merge requests on Drupal.org, so I was especially happy to see live previews added to the Generic Drupal Web Components (GDWC) project recently.
GDWC is a general project on Drupal.org and runs using NodeJS rather than PHP. Since Tugboat runs on Docker it seemed likely that we could also run Node, but the existing documentation is unsurprisingly focused on Drupal PHP projects.
