Node.js VM: Developing an External Plugin System Within Your Web App
summary
Shows a working external plugin system that runs third‑party code inside the host using the Node.js vm module: plugin source is compiled to a vm.Script, executed in a context that supplies a custom require, mock process, logger and an export object. Plugins are delivered as a scaffolded app class that receives controlled dependencies; code and bundled npm deps are persisted so apps load on restart. Notes: promises can escape timing, vm is not a security boundary, reviews or separate processes are needed.
