Access to fs and path modules from JS

[lawik]

When using escape hatches like evaluating JS or working with template expressions it would be great to have access to some basic filesystem and path operations as well as the project directory. I ran into issues with this when I was trying to get uploads working (that led to another PR and #78) but realized I couldn't easily bring in imports and I didn't have access to the variable providing the project directory from what I could determine.

Hello,
do you mean we need some way to inject JavaScript into templates with access to fs/path?
Can you show me the exact cases where you need to operate with them?

[lawik]

If I'm creating a snippet that needs to deal with relative paths or read from a file I would probably do that with the existing functionality for evaluating JS in the test suite.

But I can't put imports there. So I can't access things like fs or path. And that severely limits what I can do to work with multiple files or work around limitations for special use-cases. fs and path are fairly basic needs, so if they were exposed via Puppetry somehow that would be quite helpful.

Or if there was a way of saying "always put these import statements in". That'd be even more flexible.

I can for example expose links to fs/path in https://docs.puppetry.app/test-step/commands#page-runjs
Will it serve?

Ah you likely mean for this one #93
