Simple Express App to zip URLs on the fly and return a single zip archive. It's mostly used for mass-downloading.
Well, the code is currently 25 lines long in total so you can check it out, but nothing fancy, the app just pipes things around. It shouldn't use much memory (the size of the input doesn't matter much) and doesn't use any temporary storage.
GET /zip?urls=[comma],[separated],[list],[of],[urls]
And that's it, the download should start immediately. You can also use a POST request for longer url list.
