Great idea, didn't think of npm update, thanks

At coderdojo, we're using nodebb for forums, and a fork of cd-persona which is changing from time to time.
We'd like to know if anybody had any experience in automation of deployment of themes/plugins, our main issue being that we need an automatic reload of the forum. Being circleCi + aws based for our dev pipeline, and AWS codedeploy not supporting a custom bash post-deployment, we're slightly stuck for the automation.
Do you know of any plugin that would be a "theme/plugin-watcher"? Elsewhat I'd take any input/ideas/experience
