@fei-xie Yes, NodeBB supports that out of the box. Try composing a reply to this topic, and then close the tab. ... but give it a second or two to actually save

For a large part this is an architectural issue. It would extremely useful if it were possible to test a plugin on the production database in a development or staging environment. That's not possible when NodeBB gets the list of activated modules from the database. We have a similar problem like this with Drupal7. It's close to impossible to test something on the production data without making a copy (which is extremely unpractical with a large DB) because of the tight coupling between configuration and content. Haven't used it yet but Drupal 8 has improved on that issue quite a bit: https://www.drupal.org/docs/8/configuration-management/managing-your-sites-configuration
