Plugin for new Node.js project, how to ?

Hi,

I want to create a plugin to support another framework than Express.js, how can I do that ? I try to understand how IntelliJ plugin are working but it's quite hard to find informations for a new node plugin cause non are open source.

What I need to create a new project who is only launch an npm install ...., excecute a command and create an intelliJ project from generate project.

I look open  source plugin and I only see AbstractGithubTagDownloadedProjectGenerator class to generate project from github...

If someone can show me the way to start this it would be awesome.

Thanks
