Support K6' modules

[toolforger]

Whenever I do foo = http.post(...), IntelliJ complains that http.post is not returning a value and that that's probably an error.
The tooltip refers to a Session.http function, which I suspect is from NodeJS; anyway, it has a completely different signature than K6' Session.

I have to apologize for not providing a path to a solution, as I don't know how to tell IntelliJ what library paths to use, and I don't know if K6 has even a published list of functions they provide on each object (in fact that might be different for each K6 installation, so you'd need to provide your plugin with a path to K6' executable, and somehow make that executable spit out all the relevant data that IntelliJ needs.)

Hi Joachim!
My apologizes for the late response.
Usually, IntelliJ does recognize the k6 module type definitions (as long as they are defined as dependenices in package.json):

However, if an IntelliJ project does not define a module for your source code, it will not resolve any dependencies and so does not recognize k6 type definitions.
If it's still an issue, could you check if your project defines a module for your k6 scripts?

You can find out if your project has a module by the presence of this sign:

Unfortunately, I'm not working on the affected project anymore, so I can't confirm.
Thanks for the feedback though. I don't know if this is worth documenting for the plugin, or at least linking to a page that explains these dependency declarations? This would be useful for people who don't know Node's module system (like myself, I'm from a Java background and just wanted to use K6).
Feel free to close if this does not explain the issue well enough that you can actually do a fix; I have lost all mental context of what I was trying to achieve at the time, so I can't help more, unfortunately.

there is an official doc page regarding this: https://k6.io/docs/misc/intellisense/

Ah nice.
Maybe just put the link into the "Installation" section?

Once "Installation" section is created, I will put the link in it
