Like fs.createWriteStream(...), but atomic.
Writes to a tmp file and does an atomic fs.rename to move it into
place when it's done.
First rule of debugging: It's always a race condition.
var fsWriteStreamAtomic = require('fs-write-stream-atomic')
// options are optional.
var write = fsWriteStreamAtomic('output.txt', options)
var read = fs.createReadStream('input.txt')
read.pipe(write)
// When the write stream emits a 'finish' or 'close' event,
// you can be sure that it is moved into place, and contains
// all the bytes that were written to it, even if something else
// was writing to `output.txt` at the same time.filename{String} The file we want to write tooptions{Object}chown{Object} User and group to set ownership after writeuid{Number}gid{Number}
