Pipe a readable stream into browserify

Is there a way to pipe an already existing stream into a browserify instance? Here is an example of my use case:

fs.createReadStream('./my-entry-script.js')
  .pipe(through2(function () {
    // Some transform that pulls some meta data about the file and possibly
    // preforms modifications on the content 
  }))
  .pipe(browserify())
  .pipe(someOutputStream);

I looked into the pipeline stuff here but did not see an easy way to hook into this. I would be willing to open up a PR to take a stab at this if there is not already something to handle this situation, just wanted to start a discussion before working on it 😃

Also, FWIW, I know there are ways to solve the exact use case above, but this is for integrating browserify into a larger ecosystem of stream based transforms for content management type app I am working on. So I know there are probably ways to solve the exact problem above with a concat stream and buffer, but I would really like to be able to do the duplex stream like above.

@substack I am glad to hear that it is possible. Is my linked solution what you mean? Or is there a less hacky way?

If you can tell me the recommended solution I will try to find a place for it in the docs so anyone else with this question can easily find the answer. Thanks!!

I did manage to get a working solution, but I think there are some issues, and it is certainly hacked on top of browserify, so any help would be appreciated. Here is my implementation for reference: https://github.com/wesleytodd/rufio-filter-browserify/blob/master/index.js
