writeStream() does not create file if it doesn't exist?

Right now writeStream() starts by checking if a file exists and/or is a directory.

I'm not sure about the behavior on "file does not exist". Shouldn't the default for a write stream be to create the file if it doesn't exist?

Well .. basically I'll reference node.js's fs API.

Me too :-) I looked at that exact page before submitting the ticket...

This creates the file if it does not exist:

$ node
> const fs = require('fs')
undefined
> let s = fs.createWriteStream('FOO')
undefined
> s.write("#!/usr/bin/node\n");
true
> s.end()

In fact, opening a file for writing in node.js that does NOT silently create it actually requires quite a bit of effort - you have to use fs.open and some special flags (fs.constants.O_WRONLY | fs.constants.O_APPEND).

Okay, I think as long as it's acting consistently across different platform that would be fine 😄
