Extending a IntelliJ IDEA plugin for Webstorm Support (Javascript)

Hi, I have a working custom plugin for IntelliJ IDEA for code inspection. It is written in Java and targets Java development. I am now planning to create a similar plugin for web storm. What's the best way to do this/is there a way to modify the current plugin in such a way that it works for web storm ide for javascript? Any leads will be really appreciated. Thanks!
