Extending require() further

[somebody1234]

I would like an option which is a function that takes vm2's require as an argument and returns a new function that should be used instead of vm2's require.

Somewhat relevant: I'm using a custom file system for user submitted code. Is there a way I can manually deal with local requires, like require('./otherUserSubmittedFile'), fetching the file from the custom file system and handing it over to vm2 to then sandbox?

Update:
Very rough, but have implemented something along the lines of custom/virtual files: https://github.com/bartjoyce/vm2-with-custom-fs

Usage, would be something like this:

NodeVM.file('/customfs/main.js', {
  require: {
    external: true,
    root: '/customfs/', // restrict local requires to within the custom fs
  },
  customfs: {
    getFileContents: (filename) => /* handle /customfs/ file read */,
    exists: (filename) => /* ... */,
    isDirectory: (filename) => /* ... */
  }
})

@bartjoyce I need the same thing! Your link is broken, did you move it somewhere?

[bmewj]

@callumlocke I've since moved on to other projects and have stopped maintaining the code. The code I wrote is here: https://github.com/bartjoyce/vm2/

It's 30 commits behind, but at least you can see the modifications I've made.

Important commit is this one: bmewj@302e910

I've made additional changes to vm2 that are not in my repo. If you want to see those too, let me know.
